Introduction: Psoriasis is a chronic inflammatory skin disease characterized by plaques covered with silvery scales. Psoriasis is highly prevalent in different countries in the world, including Iran. Several studies have reported a significant association between psoriasis and cardiovascular diseases. This study aimed to evaluate the relationship between psoriasis and cardiac disease using echocardiography.Materials and Methods: This cross-sectional study was conducted in Imam Reza Hospital of Mashhad, Iran during 2013-2014 on patients with clinical diagnosis of psoriasis confirmed via biopsy. In addition, healthy volunteers homogenous in terms of age and gender were selected as the control group. Echocardiography was performed on patients and control subjects. Size of the left and right ventricles, left ventricle ejection fraction, diastolic function, and pulmonary artery pressure were recorded. In addition, patients were assessed in terms of the presence of valve regurgitation and disease severity.Results: In total, 23 patients with psoriasis and 23 control subjects were enrolled in this study. Mean duration of psoriasis was 7.0±9.1 years (range: 1-25 years), and disease severity ranged between moderate and severe. Left ventricular end-diastolic and systolic diameters were significantly higher in patients with psoriasis (P=0.030 and P=0.016, respectively). Moreover, left ventricular diastolic dysfunction was observed in 14 psoriasis patients (60.8%) and 3 control subjects (13.4%) (P

Introduction. Cutaneous leishmaniasis is one of the prevalent endemic diseases of Khorasan including Mashhad city and children bear a substantial portion of the patients. Pentavalant antimony (sbv) drugs have been considered to be the first line treatment for all clinical forms of leishmaniasis. Because there is not concise information about side effects of this compound in children group we decided to evaluate this issue in this group in a prospective study. Method. This was an analytic case -series study in which evaluation of clinical and Para-clinical (Cell Blood Count, Liver function test, Bilirubin, Amylase, Lipase, BUN, Creatinin) side effects of systemic meglumine antimoniate(glucantime) that prescribed with 20 mg/kg/day for 20 days on 89 children with cutaneous leishmaniasis whom referred to cutaneous leishmaniasis clinics of Qaem and Imam Reza Hospitals in 2010-2011 was evaluated. Data was collected in a questionnaire and then analyzed with SPSS software. Results. Average age of patients was 5.39±3.11year that 39 of them were girl and 31 boy. Clinical side effects was noted in 14 cases and the most common was erythema in injection site (13 cases) and then pain, anorexia, edema and myalgia. In 31 patients there were not any side effects. Serum levels of SGOT, SGPT, Amylase, and lipase raised at the end of treatment course that this increase for SGOT and SGPT was in normal range but increasing in serum levels of lipase and Amylase was more than upper limit of normal range in 20% and 14.3% patients, respectively. In 10% of children Hb significantly decreased lower than of normal limit. There was not any significant association between gender, age and number of treatment course with clinical and Para-clinical side effects of systemic glucantime. Conclusion. It seems that clinical adverse reaction of systemic Glucantime in children is the same with adults and changes in functional screening tests of liver and cell blood count in children is lower than adults but changes in serum amylase and lipase is more significant. So we recommend that clinical signs and symptoms of pancreatitis should be considered in children taking this drug. [ABSTRACT FROM AUTHOR]

Objective: Body hair removal plays an important role in beauty standards, particularly for women. Finding a method that is easy to use, cheap, and can be done without supervision can significantly affect long-term hair reduction and reduce the side effects of hair removal. The present study investigated the impact of a containing 20% broad bean ( Vicia faba ) extract cream on axillary hair removal., Materials and Methods: Twenty-five female volunteers were randomly divided into A (right axillary intervention - left axillary placebo) and B (right axillary placebo - left axillary intervention). Depending on the group, each person used a cream containing 20% broad bean extract )"The extract made from the seeds and pods of broad beans.") on one side and a placebo on the other twice a day for three months. Volunteers shaved their axillary hairs three days before each visit and took pictures of both sides on the day of the visit with a trichoscope (to check the diameter and thickness of the hairs)., Results: We found a decrease in thickness on the intervention group (the axilla where a cream containing broad bean extract was applied); however, this difference was not significant between the intervention side and the placebo. In terms of the number of hairs, the difference between the two groups was significant only in the second month despite the decrease on the intervention side. Evaluation based on the personal judgment of the volunteers showed that there was a substantial difference in terms of the number of hairs (p=0.012) and thinning of hair (p=0.02)., Conclusion: Our findings showed that 20% broad bean extract cream could potentially reduce axillary hair growth., Competing Interests: The authors have declared that there is no conflict of interest.

Introduction: Basal cell carcinoma (BCC) is the most common cutaneous cancer. We report the efficacy and aesthetic outcome of intralesional IFN-α 2b injection for the treatment of BCC and compare with the surgical method., Materials and Methods: Intralesional IFN-α 2b was injected in 58 BCC lesions from 20 patients three times a week for three weeks. Control group was retrospectively selected among patients who underwent surgical method (standard surgical excision) for BCC including 58 lesions from 24 patients. All patients were followed up for one year in terms of recurrence and cosmetic outcome., Results: Two patients (four lesions) failed to complete the treatment period. After three weeks, 40 (68.96%) lesions were completely cured. Nine (15.51%) lesions achieved complete healing in less than 9 sessions. Five (8.62%) lesions were completely cured by an extra week of injection. In aggregate, complete healing was observed in 54 (93.10%) lesions. In the surgery group, complete lesion elimination was detected in 52 (89.65%) lesions ( p  = 0.40). After one year, cosmetic outcome was significantly more favorable in the study group compared to the surgery group ( p  = 0.003). Recurrence was not detected in any of the groups after one year follow-up., Conclusion: Intralesional IFN-α 2b injection is an appropriate treatment choice for BCC., Clinical Trial Registry: We used Iranian registery of Clinical trials; The IRCT code is: 2017093017756N30.

Topical minoxidil solution is recommended treatment for female pattern hair loss. However, some complications, such as skin allergies, have prevented some patients from completely receiving this treatment. This study intends to evaluate the therapeutic and side effects of oral minoxidil 0.25 mg tablets treatment on FPHL and compare it with conventional treatment of 2% topical minoxidil. This study is a triple-blind randomized clinical trial in which 72 women with FPHL were treated as two separate groups. Group 1 was treated with oral minoxidil 0.25 mg tablets and topical placebo solution, while topical minoxidil solutions and oral placebo tablets were used to treat group 2 patients. In the oral minoxidil group, the average hair diameter and hair density after the 9-month treatment reached from 0.044 mm and 102 per cm 2 to 0.048 mm and 115 per cm 2 , respectively. In the topical minoxidil group, the average hair diameter and hair density from initial values of 0.044 mm and 107 per cm 2 increased to 0.047 mm and 113 per cm 2 . In both groups, the changes of hair diameter and hair density were significant compared to initial values (p < 0.001), while the trend of changes was not statically different between the two groups (p = 0.077, p = 0.674 for hair diameter and hair density, respectively) and side effects were trivial. In conclusion, oral minoxidil is an effective and new treatment for FPHL, even with a minimal dose, which can be used as an alternative treatment, especially for patients with poor compliance against topical minoxidil., (© 2021 Wiley Periodicals LLC.)

Objective: This aim of this study was to determine the effect of 1540-nm nonablative fractional erbium on macular amyloidosis., Methods: This phase-II clinical trial study has been performed with parallel group with blinding of the evaluator. The skin lesions of the patients (15 patients and 30 lesions) with cutaneous macular amyloidosis were randomly assigned into laser and no-treatment groups. In the laser group, treatment was performed by 1540-nm nonablative fractional erbium laser. Thereafter, the patients' lesions were compared in terms of pigmentation, rippling, thickness, and subjective response., Results: The lesions of the intervention group significantly improved in the three-month follow-up compared to the control group (in the control and intervention group, improved pigmentation was observed in 20 and 53.3% with p  = .02, improved rippling in 6.7 and 60% with p  = .007, diminished lichenification in 0 and 53.1% with p  = .007, and overall lesion improvement in 20 and 60% with p  = .03, respectively). In investigating the subjective response through patient global assessment, the patients in the intervention group had a greater satisfaction ( p  = .01). There was a considerable improvement of pruritus in the intervention group ( p  = .001)., Conclusions: Use of 1540-nm nonablative fractional erbium laser offered a suitable efficacy to treat macular amyloidosis without significant complications.

Background: Recent circumstantial evidence suggests increasing number of Iranian patients with cutaneous leishmaniasis (CL) who are unresponsive to meglumine antimoniate (MA), the first line of treatment in Iran. Oral meltifosine was previously reported to be effective in visceral leishmaniasis as well CL. The current study is designed to determine efficacy and safety of oral miltefosine for the treatment of anthroponotic cutaneous leishmaniasis (ACL) cases who were refractory to MA in Iran., Methodology/principal Findings: Miltefosine was orally administered for 27 patients with MA resistant ACL with approved L.tropica infection, at a dosage of ∼2.5 mg/kg daily for 28 days. Patients were evaluated on day 14 and 28, as well as 3, 6 and 12 month post treatment follow up sessions. Laboratory data were performed and repeated at each visit. Data were analyzed using SPSS version 17. Twenty-seven patients including 16 men (59.25%) and 11 women (40.74%) with mean age of 28.56 ± 4.8 (range 3-54 years old) were enrolled. Total number of lesions were 42 (1-4 in each patient). Most of lesions were on face (76.19%). Mean lesions' induration size was 2.38 ± 0.73 cm at the base-line which significantly decreased to1.31 ± 0.58 cm and 0.61 ±0.49 cm after 14 and 28 days of therapy, respectively (p value <0.05). At 12-months follow-up post treatment, 22 patients had definite/partial cure (81.48%) including 17 definitely cured patients, corresponding to a cure rate of 68% on per protocol analysis, and 62.96% according to intention to treat analysis. Recurrence of lesion was only occurred in one patient (3.70%). Nausea was the most subjective complication during the therapy (33.33%)., Conclusion: Oral miltefosine could be an effective alternative for the treatment of MA-resistant ACL., Competing Interests: The authors have declared that no competing interests exist.

Previous studies have found an association between HLA-B*1502 allele and lamotrigine-induced Stevens-Johnson syndrome (SJS)/ toxic epidermal necrosis (TEN) spectrum in Han Chinese populations. This study aims to investigate the association between HLA-B*1502 and lamotrigine- or phenytoin- induced SJS/TEN in an Iranian population. The medical records of twenty-eight lamotrigine-induced SJS/TEN patients and twenty-five lamotrigine-tolerant controls as well as eight phenytoin-induced SJS/TEN and twelve phenytoin-tolerant controls were extracted between March 2013 and March 2019 from the university hospitals in Mashhad, Iran. The presence of HLA-B*1502 allele was determined using real-time polymerase chain reaction (PCR). Among lamotrigine-induced patients with SJS/TEN, 11 (39.3%) patients tested positive for the HLA-B*1502 while only 3 (12.0%) of the lamotrigine-tolerant controls tested positive for this allele. The risk of lamotrigine-induced SJS/TEN was significantly higher in patients with HLA-B*1502, with an odds ratio (OR) of 4.74 [95% confidence interval (CI) 1.14-19.73, p = 0.032]. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HLA-B*1502 for lamotrigine-induced SJS/TEN was 39.29%, 88.00%, 78.57% and 56.41%, respectively. The HLA-B*1502 allele was present in 2 (25.0%) of phenytoin-induced SJS/TEN cases and 5 (41.7%) of the phenytoin-tolerant controls tested positive for HLA-B*1502 allele. The risk of phenytoin-induced SJS/TEN was not higher in the patients with HLA-B*1502 (OR = 0.467 [95% confidence interval (CI) 0.065-3.34, p = 0.642]). Lamotrigine-induced SJS/TEN is associated with HLA-B*1502 allele in an Iranian population but this is not the case for phenytoin-induced SJS/TEN., (© 2020 John Wiley & Sons A/S.

Background: The exact etiology of premature hair graying (PHG) remains unknown; however, oxidative stress is shown to be involved. Selenium, as an antioxidant, is widely known for its antiaging potentials. Moreover, PGH is more prevalent among addicts and because Lead is a common impurity found in illegal drug., Aims: We evaluated the serum levels of lead and selenium in patients with PHG and compared it with a control group., Patients/methods: In this cross-sectional study, 60 patients referred to Dermatology Clinic of Imam-Reza Hospital of Mashhad, Iran in 2015 were evaluated in two groups with and without PHG. Demographic information and disease characteristics, skin phenotype, and family history of PHG were recorded. Furthermore, 5 mL of brachial blood was drawn for measuring selenium and lead levels., Results: The mean patients' age was 28.1 ± 4.8 years. Age, sex, occupation, and skin phenotype in individuals with and without PHG were not significantly different (P > .05) but family history of PHG was significantly higher in the patients with PHG (P = .001). Similarly, the number of white hairs was significantly higher (P < .001), and the age of onset of hair graying was significantly lower in patients with PHG (P < .001). Serum levels of selenium and lead were not significantly different between two groups (P < .05). However, the serum levels of lead in the patients with PHG were slightly higher., Conclusions: The results of this study showed that there was no significant difference in lead and selenium serum levels in patients with and without PHG., (© 2019 Wiley Periodicals, Inc.)

Introduction: Psoriasis is an autoimmune disease. The important role of oxidative stress in the pathogenesis of psoriasis had been investigated in different studies. Thioredoxin reductase (TrxR) is a selenocysteine-containing enzyme which is involved in the protection of cells against oxidative stress. Here, we investigated the TrxR activity in skin lesions of psoriatic patients and the possible correlation between this activity and the severity of the disease that was scored based on the Psoriasis Area and Severity Index (PASI)., Materials and Methods: TrxR activity was determined using TrxR colorimetric method based on the reduction of 5,5'-dithiobis-(2-nitrobenzoic acid) to 5-thio-2-nitrobenzoic acid by TrxR using nicotinamide adenine dinucleotide phosphate in 20 psoriatic patients (11 men and 9 women) aged 38.9 ± 12.6 years. For evaluating the disease severity, PASI score system (mild [PASI <10], moderate [PASI 10-20], or severe [PASI >20]) was utilized that was based on three factors including thickness, erythema, and scaling of lesions., Results: Our results revealed that the TrxR activity between different groups of psoriatic patients (according to the PASI score) was statistically significant and it was higher in psoriatic patients with mild disease (correlation coefficient = -0.85)., Conclusion: These results further strengthen the association between psoriasis and oxidative stress. The increased level of TrxR could be due to the protective effect of this enzyme against the inflammatory process and oxidative stress. Moreover, TrxR could be used as a novel marker for evaluating psoriasis severity., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Indian Journal of Dermatology.)

Background: Old world cutaneous leishmaniasis (CL) is known as a self-healing cutaneous parasitic infection. Host immunity has a fundamental role in the course of this infection. This study was designed to investigate the relationship between nutritional status and vitamin A intake with the clinical course of CL., Methods: Overall, 250 patients with CL attending a dermatology clinic in Imam Reza Hospital Mashhad, Iran, were enrolled from Apr 2011 to Aug 2012. For data gathering, a semi-quantitative 302-item food frequency questionnaire was utilized. They received routine treatment protocols for leishmaniasis and 1 year of follow-up., Results: As for the 149 patients who completed the study, a deficiency of macro and micronutrients, particularly vitamin A, was significantly related to a chronic clinical disease course., Conclusion: Imbalanced or insufficient nutritional intake including vitamin A deficiency, may influence the clinical course of CL., Competing Interests: Conflict of interest The authors declare that there is no conflict of interests., (Copyright© Iranian Public Health Association & Tehran University of Medical Sciences.)

The aim of this study was to prepare and characterize topical methotrexate (MTX) with different percentages (0.05%, 0.1%, 0.25% and 0.5%) entrapped in deformable liposomes using phosphatidylcholine and oleic acid. The effectiveness and sub-acute toxicity of these topical formulations were investigated in imiquimod (IMQ)-induced psoriasis in a mouse model (IMQP). The particle sizes of formulations were around 100 nm with a mean zeta potential of -72.87 mV. The entrapment efficiency (EE%) of MTX in liposomal formulations were more than 85%. Franz cell permeability studies indicated that permeation of MTX through the healthy BALB/c mice skin is very low; however, in the inflammatory skin, which was induced by IMQ it was significant (50%). Liposomal MTX (LM 0.05 and 0.1%) caused significant reduction of thickness score dose-dependently in IMQP compared to the injected MTX. Moreover, investigation of the inflammatory factor and pathological examinations of skin proved the superiority of the LM treating group. Pathological examinations also showed there are no toxicity in organs of the mice that received the LM. Blood cell count test didn't show any abnormality. MTX-entrapped deformable liposomes could be a topical option in future for the treatment of human psoriasis with a less toxicity and merit further investigations., (Copyright © 2019 Elsevier B.V.

Background: Treatment of cutaneous leishmaniasis remains a challenge; new physical treatment modalities including laser systems are of interest in the treatment of localized lesions., Method: Fourteen patients (10 females) with 20 lesions of Old World cutaneous leishmaniasis underwent weekly treatments of 1540 nm erbium glass fractional laser (Palomar) using 10 mm spot size hand piece in four passes of 50-70 mJ/cm 2 fluence and 10 ms pulse duration., Results: Twelve lesions were available for assessment: six (50%) improved at 6 weeks and eleven lesions (91.7%) at 12 weeks. There were no recurrences at 6- and 12-month follow-ups., Conclusion: Erbium glass fractional laser may be an alternative treatment for localized cases of Old World cutaneous leishmaniasis., (© 2018 The Australasian College of Dermatologists.)

Background: Cardiogoniometry (CGM), a spatiotemporal electrocardiologic method may be useful as a cardiovascular diagnostic tool. Increased incidence of coronary artery or myocardial involvement and defects in automatic setting of heart activity have been reported in psoriasis which could be related to the presence of systemic inflammation. Cardiogoniometry and the related parameters have been used in this study as a diagnostic technique in psoriasis patients., Methods: Thirty patients with psoriasis and 30 healthy, age and sex-matched individuals with no history of cardiovascular diseases or traditional coronary risk factors were enrolled. Duration and severity of the disease, using psoriasis severity and area index (PASI) score were recorded. Electrocardiography and cardiogoniometry were performed. Heart rate, QT interval and QT dispersion (QTD) were measured. SDNN (standard deviation of normal R-R interval) and myocardial ischemia score were determined by cardiogoniometry., Results: There was significant difference between the psoriasis patients and the controls in terms of heart rate (76.37±14.41 vs 72.53±9.684, p=0.02), myocardial ischemia score (-1.53±2.63 vs -0.46±0.73, p=0.037), corrected QT interval (392.64±26.00 vs 377.26±22.34, p=0.017) and QTD (32.00±17.88 vs 6.67±15.16, p<0.001). No statistically significant difference was found in SDNN (36.37±21.01 vs 26.90±14.88, p=.29). There were moderate correlation between PASI and SDNN (r=0.427, p=0.009), heart rate (r=0.427, p=.009) and score (r=0.481, p=.004)., Conclusion: Abnormalities in resting ECG and CGM and their correlation with disease severity raises concerns about the need for cardiovascular follow-ups of psoriatic patients, especially those with severe disease., (Copyright © 2016.

Introduction: Hirsutism is defined as the excessive male-pattern growth of hair in women. Hirsutism is often idiopathic or the consequence of polycystic ovary syndrome (PCOS). Insulin resistance is common in PCOS (especially in obese patients) but the association between insulin resistance and idiopathic hirsutism (IH) is not clear. The aim of this study was to investigate the rate of insulin resistance in IH, compared with healthy individuals and patients with PCOS., Methods: The study included three groups, patients with idiopathic hirsutism, PCOS and healthy women. Each group included 30 non-obese women. Fasting blood sugar (FBS), insulin level and insulin resistance (estimated by the homeostasis model assessment [HOMA-IRIR]) were compared in the three groups., Results: There was a significant difference between the age of the women with IH compared with two other groups. There were no significant difference in levels of serum insulin (P = 0.49, HOMA-IR (P = 0.47) and prevalence of insulin resistance (P = 0.07) in the three groups. The age-adjusted prevalence of insulin resistance was similar in the three groups., Conclusion: Insulin resistance was no more frequent in IH patients than in healthy control groups., (© 2014 The Australasian College of Dermatologists.)

Leishmaniasis is a group of diseases with varied clinical manifestations. Ocular involvement is an unusual presentation of leishmaniasis, and the eyelid is not a common site of cutaneous lesions, likely due to the mobility of the lids. Some case reports of conjunctival involvement are either a contiguous dissemination from lid margin or in the setting of disseminated leishmaniasis in an immunocompromised host. To our knowledge, isolated involvement of the bulbar conjunctiva has not been reported. We present the first case in the literature of a patient with an erythematous fibrovascular lesion in the interpalpebral zone that was clinically diagnosed as pterygium, but recurred at the site of surgical excision. After histopathologic diagnosis, the lesion was treated with intralesional injection of amphotericin B and improved completely within a few weeks. An accurate diagnosis of leishmaniasis in the eye may be challenging in many clinical settings. To our knowledge, an isolated pterygium.like lesion has not been reported in literature. In addition, intralesional injection of amphotericin B is a novel treatment method in this setting.

Objective: Leishmaniasis has long been known as a poverty-associated disease, which is particularly prevalent in developing and less developed countries. The role of socioeconomic status in the clinical course of the disease is less clearly defined. In this study, we investigated the potential relationship between the clinical course of cutaneous leishmaniasis in terms of its evolution into chronic forms and the socioeconomic status of the patients., Methods: A total of 140 patients attending the dermatology clinic in Imam Reza Hospital, Mashhad, Iran, were enrolled. The patients were grouped into high, medium, and low socioeconomic classes according to a comprehensive questionnaire. They received routine treatment protocols for leishmaniasis and were followed up for 1 year., Results: We found a statistically significant relationship between the clinical course of the disease and socioeconomic status., Conclusion: Poverty might prolong the course of cutaneous leishmaniasis for many different reasons., (© 2014 Canadian Dermatology Association.)

Background: Antimoniate compounds have been used as gold standard treatment for cutaneous leishmaniasis since many years ago, but with increase in incidence of drug as well as individual contraindications, more attention has been given to alternative treatments., Aim: The aim of this study was to evaluate the efficacy of intralesional amphotericin B as an alternative treatment for cutaneous leishmaniasis in Mashhad, Iran, during 2007-2009., Materials and Methods: Non-random sampling from both sexes and without any age limitation of cases eligible for this alternative treatment was done. Size and induration of lesions were measured before beginning and weakly during the treatment. Amphotericin B (2 mg/ml) was injected into lesions weekly for up to 12 weeks and the cases were followed up for the treatment responses, possible side effects and recurrence of the disease., Results: A total of 93 patients with a mean age of 20.81 ± 15.26 years were included in this study. At the end of 12(th) week, 61.4% of the patients were recovered completely (more than 90% reduction in size and induration), 21.6% had partial remission (60-90% reduction in size and induration), and 17% had less than 60% reduction in size and induration of skin lesions. Injection side effects were insignificant and did not lead to premature discontinuation of treatment in any patients., Conclusion: Weekly intralesional injection of amphotericin B looks promising, considering the fact that most of the patients in this study were resistant to antimoniates.

Background: Previous studies have demonstrated that dermoscopy improves accuracy in diagnosing pigmented and non-pigmented tumors. Recently, there has been increasing evidence that dermoscopy can also be useful in the diagnosis of some skin infections., Objective: We sought to describe the dermoscopic features of cutaneous leishmaniasis., Method: Dermoscopic examination (using the Derm Lite FOTO, 3Gen) of 144 CL lesions in 82 patients was performed. This study was conducted in the Imam Reza and Ghaem hospitals (Mashhad, Iran) from October 2010 to September 2011., Results: We observed the following dermoscopic features: generalized erythema (81.9%), white starbursts (60.4%), yellow hue (43.8%), yellow teardrop-like structures (41.7%), central ulcers (59%), hyperkeratosis (33.3%), and milia-like cysts (4.9%). We also observed vascular structures, including dotted vessels (61.1%), hairpin vessels (37.5%), linear irregular vessels (30.6%), comma-shaped vessels (29.9%), glomerular vessels (22.9%), arborizing telangiectasia (10.4%), and corkscrew vessels (4.2%)., Limitations: Biopsy and pathologic evaluation were not performed due to ethical considerations., Conclusion: Important vascular patterns seen in melanocytic and non-melanocytic tumors were frequently observed in this infection. Dermoscopy may be a promising tool to predict the clinical course in cases of cutaneous leishmaniasis., (© 2013 The International Society of Dermatology.)

Objective(s): Lichen Planus is a common disease with unknown etiology which affects the skin and mucosa. Recent studies have focused on the possible role of the virus in the pathogenesis of Lichen Planus. The purpose of this study was to determine the association between the human T-cell lymphotropic virus type 1 and Lichen Planus., Materials and Methods: This case control study was conducted on a total of 200 patients. The case group consisted of 100 patients with a confirmed histopathological diagnosis of lichen planus disease, and the control group consisted of 100 healthy blood donors without any signs or symptoms of skin diseases, and who were similar in age and sex to the case group. Blood samples of both participants in the case and control groups were examined for the presence of anti -HTLV-I antibodies using the ELISA method. The polymerase chain reaction for human T-cell lymphotropic virus type 1 was conducted in cases in which the findings for antihuman T-cell lymphotropic virus type 1 antibody test was positive, and statistical analysis was conducted on the obtain results., Results: One case in the case group was infected with human T-cell lymphotropic virus type 1; however, no infection was observed in the control group. The difference was not statistically significant (P = 1)., Conclusion: Based on the obtained results, no association was observed between the human T-cell lymphotropic virus type 1 infection and Lichen Planus.
