Melanocitoma Epitelioide Pigmentado: Relato de Caso

Pigmented epithelioid melanocytoma is a rare, newly described melanocytic tumor that encompasses lesions previously classified as animal type melanomas and epithelioid blue nevus of the Carney complex. Pigmented epithelioid melanocytoma is a specific clinicopathological entity with particular clinical presentation and histological features. We present the case of a 5 year old female patient with a heavily pigmented papule on her right thigh that showed histological findings compatible with pigmented epithelioid melanocytoma and discuss the relevance /clinical significance of sentinel lymph node biopsy as a staging procedure in this particular neoplasm.Melanocitoma epitelioide pigmentado é um tumor raro, recentemente descrito que engloba lesões previamente classificadas como melanomas “tipo animal” e nevo azul epitelioide do complexo de Carney. Melanocitoma epitelioide pigmentado é uma entidade clinicohistopatológica específica com apresentação clínica e características histopatológicas particulares. Apresentaremos o caso de uma paciente do sexo feminino de 5 anos de idade com uma pápula densamente pigmentada em sua coxa direita que mostrou achados histológicos compatíveis com Melanocitoma epitelioide pigmentado e discutiremos a relevância/ significância clínica da biópsia de linfonodo sentinela como parte do processo de estadiamento dessa neoplasia em particular

Use of laser technologies and intense pulsed light in the treatment of exogenous ochronosis: a literature review

Exogenous ochronosis is a cutaneous hyperpigmentation condition caused by the accumulation of substances derived from phenol on the skin or mucous membranes without affecting other tissues. It occurs mainly due to the use of bleaching agents, most frequently hydroquinone. The lesions are difficult to treat, being resistant to several approaches. Sometimes it’s necessary to use laser technologies or intense pulsed light to achieve some degree of improvement. The present work consists of a literature review of publications on these technologies in exogenous ochronosis from January 1990 to July 2020

Epidermodysplasia Verruciformis acquired in an HIV-positive patient

The disease epidermodysplasia verruciformis is a rare genodermatosis, autosomal recessive in most cases, characterized by susceptibility to infection by types of HPV of the genus β (EV-HPV) that do not occur in immunocompetent clinics. With the increased survival of immunosuppressed patients, especially with AIDS, a form of the disease called epidermodysplasia verruciformis acquired from a clinician similar to the genetic disease has been reduced, but challenging to manage, since an antiretroviral therapy leads to a cutaneous one, making patients more resistant to any treatment modality
