Abstract Background Psoriasis is a skin disease that affects 1.3% of Brazilians. The use of teledermatology (TD) in the public health sector has democratized access to dermatological care. Objective To analyze TD exams with suspected and/or diagnosed psoriasis performed between 2016‒2020 in the state of Santa Catarina (SC). Methods Analytical cross-sectional observational study that used secondary data collected from the records of TD exams from the Telemedicine and Telehealth System (TTS) of SC. The associations were evaluated by the chi-square test and Student'st test. The significance level was set at 5% (p < 0.05). Results During the period, 6,146 TD exams were related to psoriasis, 58% due to the diagnosis provided by the reporting dermatologist and 42% exclusively due to the suspected disease on the request of the examination. The male sex predominated among the diagnoses of dermatosis (51%; p < 0.001). Regarding risk classification, psoriasis diagnoses were predominantly yellow (58.7%; p < 0.001) or blue (39.7%; p < 0.001) risk, respectively indicating moderate to severe psoriasis (referral to tertiary care) and mild psoriasis (treatment in the primary health care [PHC] level). True positive tests, suspected by PHC and diagnosed with psoriasis through TD, were 34.1% (p < 0.001). Study limitations The TD service is available only for the public health network and analysis for a limited period (five years). Conclusions Psoriasis diagnoses performed by TD, when compared to other dermatoses, tend to receive treatment at the primary (p < 0.001) or tertiary (p < 0.001) health care level, reducing the number of referrals to the secondary care level.

The polymorphism of cutaneous leishmaniasis (CL) complicates diagnosis in health care services because lesions may be confused with other dermatoses such as sporotrichosis, paracocidiocomycosis, and venous insufficiency. Automated identification of skin diseases based on deep learning (DL) has been applied to assist diagnosis. In this study, we evaluated the performance of AlexNet, a DL algorithm, to identify pictures of CL lesions in patients from Midwest Brazil. We used a set of 2458 pictures (up to 10 of each lesion) obtained from patients treated between 2015 and 2022 in the Leishmaniasis Clinic at the University Hospital of Brasilia. We divided the picture database into training (80%), internal validation (10%), and testing sets (10%), and trained and tested AlexNet to identify pictures of CL lesions. We performed three simulations and trained AlexNet to differentiate CL from 26 other dermatoses (e.g., chromomycosis, ecthyma, venous insufficiency). We obtained an average accuracy of 95.04% (Confidence Interval 95%: 93.81–96.04), indicating an excellent performance of AlexNet in identifying pictures of CL lesions. We conclude that automated CL identification using AlexNet has the potential to assist clinicians in diagnosing skin lesions. These results contribute to the development of a mobile application to assist in the diagnosis of CL in health care services.

Abstract Livedoid vasculopathy (LV) is a rare thrombotic occlusive vasculopathy presenting with chronic relapsing‐remitting bilateral painful skin ulcerations predominating on the ankles and dorsal surface of the feet. LV can be idiopathic or secondary to endothelial dysfunction, rheological disorder, haemostatic or fibrinolytic pathology. We describe the case of a 49‐year‐old patient with LV and summarise the current knowledge on epidemiology, risk factors, and treatment of this rare condition. It is important to differentiate LV from vasculitic disorders, the management of the latter being based on immunosuppression, whereas the treatment of LV is based on anticoagulant or antiplatelet therapy.

Abstract The number of skin infections caused by atypical mycobacteria has increased in recent decades. They usually appear after contact with wounds and interruptions in the integrity of the skin. The present report describes a case of cutaneous infection by Mycobacterium marinum, in a young, immunocompetent patient, with a prolonged evolution, diagnosed through a skin lesion culture (from a spindle biopsy of the skin). The patient was treated with multidrug therapy, including clarithromycin, doxycycline, and rifampicin, due to the lesion extent, with satisfactory results. A brief review of the literature is also provided.

Abstract Background: Malignant skin melanoma is a serious public health problem, especially among the elderly population. Knowing the dynamics of the mortality rates of this disease in Brazil is essential to support the creation of public health policies. Objective: To analyze the temporal trend of mortality from malignant skin melanoma in elderly people in Brazil, from 2001 to 2016. Methods: This was a descriptive analytical study of mortality rates from malignant skin melanoma in the elderly. The data were obtained from the Mortality Information System, and information related to the population was obtained from the 2010 population census and population estimates from the Brazilian Institute of Geography and Statistics. Mortality coefficients were calculated and simple linear regression analysis of the coefficients was performed by sex and macro-region. Results: A total 12,712 deaths due to malignant skin melanoma in the elderly were registered. The majority (56.8%) occurred in the male population. In females, a tendency of increase in mortality rates due to malignant skin melanoma was observed in the Northeast (p ≤ 0.001), Midwest (p = 0.002), and Brazil as a whole (p = 0.003). In males, an upward trend was observed in all regions, except for the Southeast region. For both sexes, there was also an upward trend in all regions, with the exception of the Southeast region. Study limitations: Secondary databases are directly influenced by the quality of death certificate completion and their heterogeneous scope in Brazilian regions. Conclusion: The increase in mortality indicates a potential public health challenge for the coming decades. The prevention of skin cancer among the elderly should become a priority, mainly through the implementation of preventive measures.

Abstract Background The Dermatology Life Quality Index (DLQI) is the most commonly used instrument for clinical evaluation of the impact on health-related quality of life (HRQOL) in dermatological research protocols. The DLQI’s classical psychometric properties have been considered adequate in validation studies from several countries. However, the structure of the DLQI is a matter of discussion, especially concerning the dimensionality and informative properties of its questions according to the item response theory (IRT). Methods Pooled data from studies in Brazil that utilized the DLQI to assess HRQOL in 14 dermatoses were reanalyzed. Classical psychometrical analysis, dimensionality assessment through parallel analysis and IRT (Samejima’s ordinal model) analysis were performed. Results The sample consisted of 1286 patients with a mean age of 47 years (SD = 16), and the proportion of women was 59% (765). The DLQI scores ranged from 0 to 29, with a median (p25–p75) of 5 (2–11). All items indicated significant correlations with the total DLQI score (rho > 0.54). The Cronbach’s alpha result was 0.90 (CI 95% 0.89–0.91). Parallel analysis indicated a unidimensional factor structure. According to IRT analysis, items q6 (sports) and q7 (work/study) exhibited insufficient fit to the model (p

Abstract Confluent and reticulated papillomatosis of Gougerot and Carteaud is a rare dermatosis with onset during puberty, more prevalent in females than in males. The pathogenesis is unknown, but some theories suggest either a keratinization or endocrine disorder. The lesions are verrucous, brownish, hyperkeratotic papules or spots that coalesce in a confluent and/or reticulated pattern. This report presents a case with extensive cutaneous involvement associated with acanthosis nigricans and good response to treatment with methotrexate.

Abstract: Hidradenitis suppurativa is a chronic immune mediated disease of universal distribution that causes great damage to the quality of life of the affected individual, whose prevalence is estimated at 0.41% in the Brazilian population. The objective of this work was update on physiopathogenesis, diagnosis and classification of hidradenitis suppurativa and to establish therapeutic recommendations in the Brazilian reality. It was organized as a work group composed of eight dermatologists from several institutions of the country with experience in the treatment of hidradenitis suppurativa and carried out review on the topic. Recommendations were elaborated and voted by modified Delphi system and statistical analysis of the results was performed. The Brazilian consensus on the clinical approach of hidradenitis suppurativa had the support of the Brazilian Society of Dermatology.

We report the case of a woman in her 60s with confirmed multiple self-healing squamous epitheliomas (MSSE) Ferguson-Smith. After recurrences following surgery and radiotherapy, the patient was successfully treated with minimal surgical intervention combined with intralesional injections of triamcinolone acetate. The histological comparison between mature and regressed keratoacanthomas (KA) revealed an increased inflammatory infiltrate with numerous plasmacytoid dendritic cells in the regressed KA in comparison to the mature one, speaking in favor of an inflammation-mediated regression process. Corticosteroids injection in MSSE may have paradoxical effects with action on the proliferation phase rather than the inflammatory regression phase of the KA. Our case confirms previous reports showing that radiotherapy may exacerbate MSSE and should be avoided. Intralesional triamcinolone acetate injection is a safe and easy to use method also effective for multiple lesions. Our case underlines the difference between squamous cell carcinoma and KA, responding differently to therapies like imiquimod or radiotherapy.

BACKGROUND: Melasma is a chronic, acquired hyperpigmentation disease on sun-exposed areas of the skin, which affects patients' quality of life. OBJECTIVE: To assess the impact on the quality of life of women living in Florianópolis, Brazil, through questionnaire (MelasQol), and investigate the clinical aspects and risk factors for melasma, correlating them with the MelasQol scores. METHODS: This study was performed on 51 melasma patients cared for at the University Hospital of the Universidade Federal de Santa Catarina. The variables included were: age, gender, age of onset of melasma, Fitzpatrick phototype (I-VI), duration and family history of melasma, onset of melasma during pregnancy, use of hormonal contraceptive, thyroid disorder and distribution of melasma. The MelasQoL questionnaire, validated for Brazilian Portuguese (MelasQoL-BP), was applied. RESULTS: The mean age was 38.43±6.75 years. All patients were women. The most common Fitzpatrick skin phototypes were III (49.02%) and IV (33.33%). Melasma had a mean age of onset of 29.18±7.05 years and a mean duration of 9.25±6.18 years. The majority of patients did not have familial history of melasma (50.98%). Melasma onset was associated with pregnancy (45.10%). The MelasQoL-BP analysis revealed significant emotional impact on patients, such as feeling bothered (94.11%), frustrated and embarrassed (64.71%), and depressed (52.94%) about their skin appearance, as well as unattractive (78.43%). No social impact was observed (P>0.05). CONCLUSION: Melasma has a strong emotional impact on quality of life, resulting especially from feelings about skin appearance.

BACKGROUND: Telemedicine refers to the use of technology as improvement of healthcare delivery to places where distance becomes an obstacle. Its use represents a great potential for dermatology, a specialty whose visual analysis phase is essential in diagnosis. OBJECTIVES: To analyze the compatibility index of skin cancer diagnoses between primary care and teledermatology, and to validate a protocol for standardization of digital imaging to obtain the reports in teledermatology. METHODS: An observational cross-sectional study developed through the census of 333 examination requests, received between January/2012 and July/2012, in the Center for Telemedicine and Telehealth of SES-SC. We used a protocol for photographic lesion standardization, consisting of three steps (panoramic photo, close-up with ruler and dermoscopy). After collection, the data were sent to a virtual site on the Internet, and recorded with the use of an electronic health record containing the images, the skin phototype and demographic characteristics. RESULTS: The level of compatibility between the diagnosis of skin cancer in Santa Catarina's primary care and the diagnosis proposed by teledermatology was 19.02%. Proportionally, it was 21.21% for BCC, 44.44% for SCC and 6.98% for MM. The protocol was statistically significant (p

Abstract: Dermatofibroma is a frequent benign tumor of easy clinical diagnosis in most cases, but that can mimic other dermatoses. Dermoscopy may help to define the diagnosis and its classical pattern is a central white area, similar to a scar, surrounded by a discrete pigment network. However, dermoscopic findings are not always typical. We describe here a case of dermatofibroma exhibiting ridges, furrows and pseudocomedos, a pattern which is typical of seborrheic keratosis, in dermoscopy.

AbstractIn Brazil, visceral Leishmaniasis is caused by Leishmania chagasi. The development of cutaneous lesions in visceral leishmaniasis patients has been described in two different clinical contexts. Patients with compromised immunity can develop skin lesions as a direct consequence of a current visceral disease. Equally, patients with a history of kala-azar and progressive, immune improvement occasionally develop skin lesions as a consequence of immune reconstitution infl ammatory syndrome. These cases manifest in similar fashion to the classic form of post-kala-azar dermal Leishmaniasis. We describe different cases that exemplify these two clinical presentations.

BACKGROUND: Dermoscopy allows the early detection of melanomas. The preoperative determination of Breslow index by dermoscopy could be useful in planning the surgical approach and in selecting patients for sentinel lymph node biopsy. OBJECTIVES: This study aims at describing the dermoscopic features of thin melanomas and comparing melanomas in situ with invasive melanomas less than or equal to 1 mm thick. METHODS: This was an observational retrospective study in which the dermoscopy photographs of 41 thin melanomas were evaluated. Three observers evaluated together 14 dermoscopic criteria. RESULTS: Among thin melanomas, the most frequent criteria were presence of asymmetry in two axes in 95% of cases (39 cases), 3 or more colors in 80.4% of cases (33 cases), atypical dots or globules in 58.5% of cases (24 cases) and atypical network or streaks in 53.6% of cases (22 cases). The group of invasive melanomas presented with a higher frequency and statistical significance (p

FUNDAMENTO: O vitiligo é considerado a hipomelanose adquirida mais frequente. Apesar de sua etiopatogenia ser incerta, acredita-se que a etiologia autoimune seja a mais plausível, teoria que se fundamenta na concomitância de vitiligo com doenças autoimunes. OBJETIVOS: Traçar o perfil epidemiológico dos pacientes com vitiligo e estimar a prevalência da associação de vitiligo com doenças autoimunes da tireoide. MÉTODOS: Efetuou-se um estudo transversal, analisando-se prontuários dos pacientes com diagnóstico de vitiligo atendidos no Ambulatório de Dermatologia AME-Unisul e do HU-UFSC. Avaliaram-se as características clínicas e laboratoriais desses pacientes. RESULTADOS: Foram avaliados 85 prontuários, sendo 56 do sexo feminino, com idade média de 37,14 anos e idade média de início de 25,25 anos. O vitiligo vulgar ocorreu em 70,6% dos casos. As doenças autoimunes da tireoide foram encontradas em 22,4% dos casos. Outras doenças autoimunes foram identificadas em 5,9% dos casos. Os pacientes com anticorpos antitireoidianos positivos revelaram uma probabilidade elevada de extensão do vitiligo maior que 25%. Não houve diferença estatística quanto às características clínicas do vitiligo em portadores ou não de tireoidite autoimune com alteração hormonal. CONCLUSÃO: Os resultados deste estudo são similares aos de outros autores, mostrando que as doenças autoimunes da tireoide são mais frequentes nos pacientes com vitiligo.BACKGROUND: Vitiligo is considered the most frequent acquired hypomelanosis. Although its pathogenesis is uncertain, it is believed that autoimmune etiology is the most plausible. This theory is based on the coexistence of vitiligo with autoimmune diseases. OBJECTIVES: To describe the epidemiological profile of vitiligo patients and to estimate the prevalence of the association of vitiligo with autoimmune thyroid diseases. METHODS: A cross-sectional study was conducted through analysis of the medical records of patients diagnosed with vitiligo in the AME-UNISUL Outpatient Clinic of Dermatology and at HU-UFSC. The clinical and laboratorial characteristics of these patients were assessed. RESULTS: 85 medical records were evaluated; 56 patients were female, with a mean age of 37.14 years and mean onset age of 25.25 years. Vitiligo vulgaris occurred in 70.6%. Autoimmune thyroid diseases were found in 22.4%. Other autoimmune diseases were identified in 5.9%. Patients with positive thyroid autoantibodies showed a probability of extension of vitiligo greater than 25%. There was no statistical difference with regard to the clinical characteristics of vitiligo in patients with or without autoimmune thyroiditis with hormonal change. CONCLUSION: The findings of this study are similar to those obtained by other authors, showing that autoimmune thyroid diseases are more common in patients with vitiligo.

OBJETIVOS: Estabelecer dados epidemiológicos do carcinoma de células escamosas da pele em Tubarão (Santa Catarina). MÉTODOS: Laudos anatomopatológicos positivos para o carcinoma de células escamosas da pele dos laboratórios de Tubarão foram revisados quanto às variáveis: ano, idade, gênero, localização, subtipo histológico, maior diâmetro da lesão e comprometimento das margens. A incidência anual foi calculada utilizando o número de neoplasias encontradas e a população anual estimada para os anos de 2000, 2003 e 2006. RESULTADOS: Foi encontrada uma incidência de carcinoma de células escamosas da pele por 100.000 habitantes de 50,86 para o ano de 2000, de 71,16 para 2003 e de 94,39 para 2006. Não houve predomínio de gênero, a face foi o local de acometimento mais frequente em ambos os gêneros e o subtipo histológico mais comum foi o bem diferenciado. CONCLUSÃO: A incidência do carcinoma de células escamosas da pele encontrada superou a estimativa da literatura consultada. Houve aumento na sua incidência; as variáveis idade, localização e tipo histológico foram concordantes com a literatura, porém a distribuição quanto ao gênero se mostrou diferente.BACKGROUND: A worldwide increasing trend in the incidence of squamous cell carcinoma of the skin has been observed but there are no studies regarding the incidence of this cancer in the Southern region of the State of Santa Catarina. OBJECTIVES: To establish epidemiological data regarding squamous cell carcinoma of the skin in Tubarao (state of Santa Catarina). METHODS: Anatomopathological reports, positive for squamous cell carcinoma of the skin, found in laboratories of the city of Tubarao, were analyzed regarding year, age, gender, site, histological subtype, largest diameter, and biopsy margins. The annual incidence was calculated using the number of neoplasias found and the estimated population for the years 2000, 2003, and 2006. RESULTS: The incidence of squamous cell carcinoma of the skin per 100,000 habitants was 50.86 for the year 2000, 71.16 for 2003 and 94.39 for 2006. There was no gender dominance, the face was the most frequent location affected in both genders, and the most common histological subtype was well differentiated tumor. CONCLUSION: The detected incidence of squamous cell carcinoma of the skin surpassed the incidence estimated in the literature. There was a considerable increase in its incidence; the variables age and location agreed with information found in the literature but gender distribution differed.

RESULTS: The patients' profile was: female, white, 51.3 years of age, with invasive melanoma on the trunk and limbs, extensive spreading type, Breslow 2.63 mm. The mortality rate was 7.0%, greater among men (11.1%), Breslow above 4.0 mm (66.0%), with ulceration (33.3%) and stage IV (80.0%). The average survival period was 56.7 months. Conclusions: The mortality rate of primary cutaneous melanoma was 7.0%; ulceration and the final staging were the factors with statistic significance on the result.

FUNDAMENTOS: As onicomicoses são infecções fúngicas responsáveis por 15 a 40% das doenças ungueais. Apesar do pleno conhecimento de seus agentes etiológicos e do surgimento de inúmeros medicamentos antifúngicos, mantêm-se as dificuldades para se estabelecer diagnóstico correto. OBJETIVOS: Comparar o exame micológico direto, o histopatológico e a cultura dos pacientes com suspeita de onicomicose e verificar a sensibilidade e especificidade de cada método. MÉTODO: Foram selecionados 40 pacientes com suspeita clínica de onicomicose e avaliados os três métodos diagnósticos. Calculou-se para cada exame: sensibilidade, especificidade e valores preditivos, positivo e negativo. RESULTADOS: O exame micológico direto foi positivo em 29 pacientes (72,5%), o histopatológico em 14 (35%), a cultura em 22 (55%). As especificidades foram: exame micológico direto 78,6%, histopatológico 92,9% e cultura 100%. As especificidades não apresentaram diferença significativa (p > 0,05). Na análise dos valores preditivos positivo e negativo, a cultura e o exame micológico direto obtiveram maior eficácia, respectivamente. CONCLUSÕES: O exame micológico direto foi o mais confiável para seu resultado negativo. A cultura mostrou-se específica quando positiva. Quanto à biópsia, não se mostrou sensível e apresentou especificidade equivalente à dos outros exames.BACKGROUND: Onychomycoses are frequent fungal infections, responsible for 15% to 40% of nail plate diseases. In spite of great existing knowledge on the etiological agents and of the emergence of numerous antifungal drugs, difficulties still remain in making a correct diagnosis. OBJECTIVE: To compare direct mycological examination, histopathology and culture of patients with suspicion of onychomycosis and to verify the sensitivity and specificity of the methods. METHODS: Forty patients with clinical suspicion of onychomycosis were chosen and evaluated with the three diagnostic methods. For each of the methods, sensitivity, specificity, predictive positive value and predictive negative value were calculate. RESULTS: Direct mycological examination was positive in 29 patients (72.5%), histopathology in 14 (35%), and culture in 22 (55%). Found specificities were: direct mycological examination: 78.6%, histopathology: 92.9% and culture: 100%. There were no significant differences in the specificity of the methods (p > 0,05). In the analysis of the predictive positive value and the predictive negative value, culture and direct mycological examination had the largest efficacies, respectively. CONCLUSION: Direct mycological examination was the most reliable exam when its result was negative. Culture showed specificity when positive. As to the biopsy, it was found not to be sensitive and presented equivalent specificity to the other evaluated exams.

FUNDAMENTOS: A importância do diagnóstico e intervenção precoces nos casos de melanoma cutâneo é vital para o prognóstico do paciente.

MÉTODO: Analisados 396 laudos de 332 pacientes com diagnóstico histopatológico de melanoma, de dois centros de serviços de Anatomia Patológica, em Florianópolis, entre 1º de janeiro de 1999 e 31 de dezembro de 2004. O protocolo, com base no questionário do Grupo Brasileiro de Melanoma, incluiu sexo, idade, localização, especialidade requisitante e espessura do tumor (índice de Breslow). RESULTADOS: Foram observados 186 melanomas in situ e 210 invasivos, predominantemente em mulheres (56%). O pico etário ocorreu entre a quinta e a sexta décadas. O índice de Breslow foi semelhante nos grupos masculino e feminino (p = 0,424), mas apontou diferença entre a dermatologia (1,852mm) e demais especialidades médicas (4,383mm), com p = 0,037. Número maior de ulcerações foi encontrado no grupo diagnosticado pelos cirurgiões gerais (p = 0,05). Os dermatologistas diagnosticaram 217 melanomas cutâneos (54%), e a maioria dos tipos clínicopatológicos, exceto o acral. CONCLUSÃO: O papel do dermatologista é fundamental para o diagnóstico precoce do melanoma cutâneo, que permite modificar o curso natural da doença.BACKGROUND: Early diagnosis and intervention in melanoma cases are crucial for prognosis. OBJECTIVE: To compare the results of cutaneous melanoma cases diagnosed by different medical specialists, in the city of Florianopolis, Brazil. METHOD: A total of 396 reports of 332 patients with histopathological diagnosis of melanoma were analyzed. The reports were collected from two laboratories in Florianopolis from January 1st, 1999 to December 31st, 2004. The protocol was based on the questionnaire of the Brazilian Group of Melanoma, including sex, age, lesion site, medical specialty that ordered the exam and tumor thickness (Breslow index). RESULTS: Our findings showed 186 melanomas in situ and 210 invasive melanomas, predominantly in females (56%). The incidence peak was between the 5th and 6th decades of life. Breslow index was similar in both male and female groups (p = 0.424). The mean Breslow index was 1.852mm for dermatology and 4.383mm for other medical specialties (p = 0.037). A higher number of ulceration was found in the group diagnosed by general surgeons (p = 0.05). Dermatologists diagnosed 217 (54%) cutaneous melanomas from the sample and most clinical histological types, except for the acral type. CONCLUSION: The role played by dermatologists is essential for early diagnosis of cutaneous melanoma, therefore changing its outcome.

A variety of cutaneous lesions can mimic melanoma, such as melanocytic nevi, lentigines, seborrheic keratosis, blue nevi, pigmented basal cell carcinomas and dermatofibromas. This report describes a rare clinical case of a female patient who presented a lesion on the left thigh, which was clinically and dermoscopically compatible with melanoma. The patient underwent excision of the lesion, and histopathology confirmed a diagnosis of pigmented Bowen’s disease. The purpose of this report is to draw attention to the fact that pigmented Bowen’s disease, a rare form of squamous cell carcinoma in situ, should also be considered as a differential diagnosis of malignant melanoma.

Desta forma, o dermatologista é frequentemente o primeiro profissional a ter contato com o paciente. A condição tem sido pouco descrita em revistas dermatológicas. Apresentamos um caso clássico da tríade completa.

Uma variedade de lesões cutâneas pode simular melanoma, tais como nevos melanocíticos, lentigos, ceratose seborreica, nevo azul, carcinoma basocelular pigmentado e dermatofibromas. Relata-se um caso clínico raro de uma paciente do sexo feminino que apresentou lesão em coxa esquerda clínica e dermatoscopicamente compatível com melanoma. A paciente foi submetida à exérese da lesão e o histopatológico diagnosticou doença de Bowen pigmentada. O objetivo é alertar que a doença de Bowen pigmentada, uma forma rara de carcinoma espinocelular in situ, também deve ser lembrada como diagnóstico diferencial de melanoma maligno.

Abstract: Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Abstract: Background: Non-melanoma skin cancer accounts for a third of all malignancies registered in Brazil, with squamous cell carcinoma (SCC) being one of its subtypes. It develops in photo-exposed areas, affecting social habits and causing negative influence on quality of life (QoL). Objectives: To evaluate QoL in patients with primary cutaneous SCC. Methods: A cross-sectional study was performed in patients with clinical diagnosis of SCC, corroborated by dermoscopy and confirmed by histopathology; prior to resection of the tumor using the double-blade scalpel technique, a questionnaire on the Dermatology Life Quality Index (DLQI) was applied. Results: Among the 46 evaluated patients, mean age was 67.1 ± 16.0 years, with a predominance of males, low educational level and socioeconomic status, Fitzpatrick II phototype, history of outdoor work, and tumor location in exposed photo areas. Mean DLQI was 4.02 ± 0.63, and in the categorization, 11 (23.9%) had a moderate to severe negative effect on QoL. The skin tumor had a negative impact on daily activities (33% of cases), treatment effects (30%), and symptoms and feelings (29%). Study limitations: There is no gold standard instrument for assessing QoL in dermatological patients. Conclusion: In the study sample, one-fourth of patients with SCC had a moderate to severe negative effect on quality of life.
