ABSTRACT
Abstract Histoid leprosy is considered a rare form of lepromatous leprosy. Its peculiar clinical picture makes its diagnosis a challenging one, which can delay starting treatment and perpetuate the disease as endemic. In addition to representing a reservoir of bacilli, and being an important means of contamination, these patients have greater resistance to standard treatment. This is a report of a typical case of this rare presentation, aiming to share the knowledge and favor earlier diagnosis of the disease.

Abstract Dermatofibrosarcoma protuberans is a rare mesenchymal tumor; it is locally aggressive and presents high rates of local recurrence. It may present as a nodular or plaque vegetating lesion. It mainly affects the trunk and proximal limbs, being rare in the distal extremities. Biopsy and immunohistochemistry help confirm the diagnosis. The authors report a case of dermatofibrosarcoma protuberans with plantar region involvement, a rare presentation. To the best of the authors' knowledge, only 11 cases of involvement of the feet were described in the international literature.

Abstract: Pyoderma gangrenosum (PG) is an uncommon neutrophilic dermatosis, with variable clinical features, nonspecific histopathology and multifactorial pathogenesis, posing a challenging diagnosis for the dermatologist. Pyoderma gangrenosum is a diagnosis of exclusion and should be included in the differential diagnoses of the verrucous syndrome. We report a granulomatous variant affecting the face.

A onicomicose é uma doença muito prevalente em nosso meio, cujos tratamentos atuais apresentam baixas taxas de cura, potenciais efeitos adversos e interações medicamentosas que limitam seu uso. Estudos recentes apresentam a laserterapia como uma nova opção terapêutica segura e eficaz. Foi realizado este tratamento em 12 pacientes, num total de 20 unhas acometidas, com 3 sessões de aplicação do laser Nd:YAG 1064nm pulso longo, com intervalo de duas semanas entre elas. Os resultados corroboram os dados atuais de boa resposta clínica e segurança deste novo método.
Onychomycosis is a very common condition in Brazil and one whose current treatments yield low cure rates, potential adverse effects, and drug interactions that limit their use. Recent studies have demonstrated laser therapy as a new, safe, and effective treatment option. This treatment was performed in 12 patients (with a total of 20 affected nails), with 3 application sessions of 1,064nm long pulse Nd:YAG laser, in two-week intervals. The results corroborate the current data of good clinical response and safety.
