Background: Acquired perforating dermatosis (APD) comprises an uncommon group of skin disorders that develop in adulthood in association with systemic diseases. The aim of this study was to characterize clinicopathologic features and treatment outcomes in a series of patients diagnosed with APD., Methods: Retrospective study of all patients diagnosed with an APD over a 10-year period (2009-2018) at a tertiary teaching hospital in Lisbon, Portugal., Results: Fifty-seven patients with APD were identified. Thirty-five patients presented lesions in multiple anatomic areas (61.4%), and the lower limbs were the most common location. Forty-six patients reported pruritus (80.7%), which was classified as severe in 21 of them (36.8%). An underlying systemic disease was identified in 53 patients (93.0%). Diabetes mellitus (DM) and chronic kidney disease (CKD) were the most common associated systemic diseases, but psychiatric disorders, malignancies, and chronic infections were present in a significant number of patients. The combination of topical steroids with antihistamines was the most prescribed initial treatment, but only 37.8% of the patients had a complete response. Acitretin, systemic steroids, and phototherapy were the treatments associated with the best outcome., Conclusion: Acquired perforating dermatosis can be associated with many systemic disorders that have pruritus as a common factor. Chronic viral infections and an occult malignancy should be sought, particularly in the absence of DM and CKD. The management of APD is challenging and is best achieved with the control of the underlying systemic diseases., (© 2019 The International Society of Dermatology.)

Nowadays, due to the increasingly frequent migratory circuits in Europe and the increment of the migrant population in Portugal, mainly in the Lisbon metropolitan area, it is more and more common to find several dermatological conditions and disorders in Africans seen in our health care system. There are few studies on dermatoses in these populations. It is important to know the biologic and physiologic differences of black skin in order to understand both the pathophysiology and manifestations of dermatoses. The recognition of many of them represents a challenge to any clinician due to the specific characteristics of their skin. It is thus essential to know the different patterns and frequencies of skin diseases in Africans, in order to optimize the diagnosis, approach and treatment.

Background: With the increasing number of HIV-infected patients receiving highly active antiretroviral therapy (HAART), the shift in their dermatologic profile becomes less characteristic of AIDS-defining illnesses., Methods: Retrospective review of mucocutaneous pathology among patients seen at HIV-Dermatology Clinic from January 2009 to December 2013., Results: Among 534 patients, there were 68.4% males and 31.6% females, with 8.7-year average duration of infection; 82.8% were receiving HAART. Kaposi sarcoma was the only relatively frequent AIDS-defining disease. Fungal and viral infections were common, with human papilloma virus (HPV) as the most frequent overall. Benign and premalignant tumors were associated with HAART and CD4 >200/mm 3 ( P < .05). Psoriasis was prevalent among patients without HAART ( P < .05). Prurigo was associated with lower CD4 count ( P < .001)., Conclusion: Patients receiving HAART are faced with chronic skin problems such as benign and premalignant tumors, and HPV infection adds to their neoplastic predisposition. Further research is recommended to develop protocols for treating psoriasis and screening for HPV-associated neoplasia among patients.

Background: Immunosuppressive therapy, which is necessary to avoid graft rejection in renal transplant recipients, presents an increased risk of several pathologies, namely infectious and neoplastic., Objectives: To identify the most frequent skin diseases and their clinical and demographical risk factors within a population of renal transplant recipients., Methods: A retrospective study of renal transplant recipients referred to dermatology visit and observed for the first time from January 2008 to December 2014., Results: The study included 197 patients, 120 men (60,9%). Mean age was 50,7 years (±13,4). 12 patients (6,1%) had previous skin cancer. Infections were the most frequent reason of referral (93/197; 44%). From the total referred, 18,3% (36/197) presented pre-cancerous lesions. Malignancy was diagnosed in 36 patients (18,3%), with 29 non-melanoma skin cancers (14,7%) and 7 Kaposi sarcomas (3,6%). Ratio of basal cell carcinoma to squamous cell carcinoma was 1,1:1. Non-melanoma skin cancer was significantly associated with older age (p = 0,002), male gender (p = 0,028), history of previous skin cancer (p = 0,002) and higher duration of immunosuppressive therapy (p<0,001)., Study Limitations: Retrospective study, with data from the first visit in dermatology. We didn't made classification on skin-types., Conclusions: The great incidence of cutaneous infections and skin cancer is responsible for a significant morbidity. It is important to assure the regular dermatological follow-up of renal transplant recipients, which will promote the prevention, an early diagnosis and an efficient treatment.

The differential diagnosis of long-lasting erythematous skin nodules in patients living in Africa is broad. We report a clinical case of a 65-year-old Caucasian male, living in a Southern African Country, presenting to our department with an eight- -month history of erythematous skin nodules on the trunk and limbs. The diagnosis was B-pseudolymphoma and we discuss its aetiology and differential diagnosis. [ABSTRACT FROM AUTHOR]

Context: A variety of nonvenereal diseases can affect the penis and diminish quality of life. Many present similar clinical features and a cutaneous biopsy may be necessary to clarify the diagnosis. Aims: To characterize nonvenereal penile dermatoses with histological confirmation in a southwestern Europe hospital during a 9-year period. Materials and Methods: A retrospective study was conducted. We reviewed all penile biopsies performed between January 1, 2007 and December 31, 2015 and studied the causes of the nonvenereal penile dermatoses. Results: The sample included a total of 108 patients, aged 62.9 (±17.8) years, between 16 years and 96 years of age. Eighteen dermatoses were identified. Inflammatory diseases were present in 65. 7% of patients (71/108) and neoplastic dermatoses in 34. 3% (37/108). Concerning inflammatory dermatoses, the most frequent were Zoon balanitis (27.8%, 30/108), followed by lichen sclerosus (15.7%, 17/108), psoriasis (11.1%, 12/108), and lichen planus (4.6%, 5/108). In patients with psoriasis, 10 had lesions only in the penis, similarly to all patients with lichen planus. The most frequent malignant tumor was squamous cell carcinoma (SCC) (15.7%, 17/108). The most common in-situ tumor was erythroplasia of Queyrat (8.3%, 9/108). A case of basal cell carcinoma (BCC) was found. Kaposi sarcoma and mycosis fungoides on penis were also diagnosed, as an additional form of presentation to their generalized disease. Conclusions: In this study, inflammatory diseases were the most frequently diagnosed dermatoses, while SCC was the most common malignant tumor found. In the majority of psoriasis and lichen planus cases, clinical lesions were only present in the genital area. [ABSTRACT FROM AUTHOR]

Anogenital infection by human papillomavirus (HPV) is the most common sexually transmitted infection (STI). It bears oncogenic potential, causing most cases of cervical, vulvar, vaginal and anal cancer. There is no specific antiviral therapy and the treatment of HPV-associated neoplasms does not prevent transmission. Thus, prevention of infection is particularly important, and the Venereology consultation is a privileged opportunity to identify people who benefit from preventive measures. The most recent nona-valent HPV vaccine provides coverage for types 6, 11, 16, 18, 31, 33, 45, 52 and 58, which together account for 90% of cancers of the cervix and genital warts. The vaccine is recommended by the WHO for women and men up to 26 years old. In most countries, the vaccine is provided freely to ensure universal immunization of female adolescents prior to the commencement of sexual activity. In addition to the target population, the vaccine may benefit other individuals often treated by dermatologists: men who have sex with men, immunocompromised hosts such as organ-transplant and HIV-seropositive patients, and candidates for immunosuppressive treatments. The decision to vaccinate should consider the individual risk of prior exposure to HPV and the potential benefit of vaccination, which is prophylactic and not therapeutic. We review published data on the immunogenicity, safety and efficacy of the HPV vaccine in different clinical contexts, and international recommendations that may guide individual counseling by the dermatologist.
