A doença de Bowen consiste em um carcinoma de células escamosas in situ sendo a forma pigmentada da doença uma apresentação incomum. Os autores descrevem um caso de doença de Bowen Pigmentada em um paciente do sexo masculino, 56 anos, com lesão em placa hipercrômica e assintomática na superfície anterior da coxa direita há 10 anos. O exame histopatológico evidenciou queratinócitos atípicos em toda extensão da epiderme com perda de polaridade, pigmentação melânica na camada basal e infiltrado linfocitário liquenóide. Foi realizada excisão completa da lesão com margem ampla não havendo recidiva. Apesar de relativamente rara, a doença de Bowen variante pigmentada deve ser sempre lembrada e incluída no diagnóstico diferencial do melanoma, assim como outras lesões pigmentadas.PALAVRAS-CHAVE – Doença de Bowen; Pigmentação; Exposição solar.
Hypopigmented mycosis fungoides (HMF) is an uncommon variant of cutaneous T-cell lymphoma. It is more frequent in dark-skinned people, particularly children. The HMF diagnose is difficult, especially in early stages because this condition resembles benign skin diseases. Thus is histopathological analysis very important for the diagnosis. We report a case of a 7-year-old child with widespread HMF confirmed by histopathology that showed cells tagging along the dermal/epidermal junction and extending into the epidermis in a pattern of epidermotropism and focal cell aggregates in the epidermis (Pautrier's microabscess). We demonstrate the importance of clinical suspicion for this cutaneous neoplasia in patients with hypopigmentated lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
