“…In various studies, BSLs were mostly seen in women (53.7%-63.2%) (Bertanha et al 2016;Sinikumpu et al 2014). In the present study, 56% (n = 310) of all BSLs were found in males, and 47.7% (n = 241) were found in females.…”

Skin lesions are commonly benign in nature. The present study aims to evaluate the prevalence and clinicopathological characteristics of a large series of benign skin lesions (BSLs) excised in our clinic. Patients with skin lesions who underwent total excisional biopsy at the general surgery clinic between 2012 and 2016 were reviewed. A total of 551 patients with BSLs were included in the study. Of these, 43.7% were females and 56.7% were males. The age range was between 2 and 98 years with a mean of 39.7 years. The most commonly occurring group of BSLs was of the appendageal tumors (33.3%), and this finding was statistically significant. The most common keratinocytic BSL (13.6%) was verruca vulgaris. In the present study, various types of BSLs and their occurrences were evaluated. Benign skin tumors can turn into malignant types. A biopsy should be performed to establish the exact diagnosis. We performed an excisional biopsy to confirm the diagnosis.

Background: Nail apparatus melanoma (NAM) is rare. The higher mortality reported in the literature is most likely due to advanced disease associated with delayed diagnosis and treatment. Objective: All patients diagnosed with NAM were followed at a single reference center during a period of 10 years, with emphasis on dermatological and histological findings. Clinical outcomes were included. Methods: A retrospective review of medical records, photographs, and histopathological examination. Results: 73.7% of the patients were female and their mean age was 47 years. Caucasian and African-American patients had a similar incidence (47.4%). There was only 1 Asian patient in this study (5.3%). All patients presented with nail plate pigmentation. The mean prediagnosis duration was 33 months. A total of 63.2% patients had in situ melanoma and an average Breslow index of 2.18 mm in invasive cases. Fifteen patients underwent conservative surgery and 3 underwent phalanx amputation. All patients survived, and 4 have had more than a 5-year follow-up. Conclusion: In situ lesions showed longitudinal bands or total melanonychia with no nail dystrophy. Invasive cases presented with dystrophic lesions (longitudinal splitting of the nail). Conservative surgery provides a good option without worsening the prognosis. All dermatologists should be aware of early signs of NAM, since prognosis depends on early treatment.

Background: The study of the epidemiological chain of dermatophytosis, particularly those related to zoophilic fungi, is extremely important because of its frequent occurrence, the high infectivity of the agent, and its anthropozoonotic character. In all latitudes, asymptomatic cats are considered the main reservoirs and sources of dermatophyte infection. The study aimed to characterize the frequency of dermatophyte infection and the potential risk of microsporic infection to the owners and to possible buyers of apparently healthy Persian cats from commercial catteries of São Paulo, Brazil.Materials, Methods & Results: Fur samples were obtained from 61 clinically healthy Persian cats, which were devoid of typical cutaneous lesions and had negative results in Wood’s lamp examination. The average age of the cats was 37.7 months; 18 (29.5%) of them were males and 43 (70.5%) were females. The cats were from commercial catteries located in the metropolitan region of São Paulo state capital. Samples were obtained using the technique of Mariat & Adam using a square (25 cm2) of sterile carpet rubbed across the surface of the hair-coat and skin. People who had close contact with the animals were asked whether they had had typical ringworm lesions in the recent past or at the time of sample collection. The material collected was pressed onto Petri dishes containing agar supplemented with chloramphenicol and cycloheximide. The Petri dishes were handled under sterile conditions and incubated at 25°C for up to 21 days. There was evident fungal growth in 83.6% of the samples, and the only dermatophyte isolated was Microsporum canis. The results were analyzed using the chi-square test in order to verify possible associations between variables (sex and age range) and the frequency of dermatophyte infection in dermatologically healthy animals. However, there was no statistical difference regarding sexual predisposition (P value = 0.139) and age (P value = 0.224) regarding the asymptomatic dermatophyte carriers. Of the 18 people who had close contact with infected cats, eight (44.4%) claimed to have presented with typical tinea corporis lesions in the past and three (16.7%) said that they had such skin lesions at the time of harvest of the cat fur. There were no people who claimed to have been in contact with other species.Discussion: In Brazil, fungal infections represent up to 8.7% of skin diseases in children, and tinea capitis caused by Microsporum canis is the most common superficial mycosis in this age group. Its interspecies transmission has been reported for decades. Approximately 50% of individuals exposed to symptomatic or asymptomatic cats acquire the disease. In up to 70% of families with infected cats, at least one family member may develop the disease. Among domestic cats, the Persian breed is most often cited as prone to spreading dermatophytes. In the study, there was fungal growth in 83.6% of the samples, and only M. canis was isolated. Among the people who had contact with the cats, 44.4% and 16.7% had typical tinea corporis lesions in the past and at the time of the interview, respectively. However, it is speculated that the rate of infection may have been higher in the humans in contact with these cats, since there may have been some hesitation and fear by the people interviewed in reporting the occurrence of characteristic skin lesions, either as a way of preserving the cattery reputation, or to spare the embarrassment in declaring oneself as infected, which is sometimes viewed negatively. The results demonstrate the potential infectivity, pathogenicity, and risk of microsporic infection in buyers of apparently healthy cats from commercial catteries located in the metropolitan region of São Paulo.
