RESUMO
O nevo sebáceo de Jadassohn é hamartoma benigno congênito da pele, mais incidente no couro cabeludo, podendo apresentar-se na face. Devido ao potencial de malignização, sua excisão muitas vezes se faz necessária. Lesões situadas no couro cabeludo constituem desafio ao cirurgião devido às características anatômicas do local, com escassez e inelasticidade da pele adjacente. Neste relato, apresentamos um caso de excisão de nevo sebáceo de Jadassohn no couro cabeludo, com fechamento da ferida operatória por retalho de rotação bilateral, técnica muito simples e versátil, excelente para topografias de difícil reconstrução, como o couro cabeludo.
The nevus sebaceous of Jadassohn is a congenital benign hamartoma of the skin that occurs more frequently in the scalp, but can also arise in the face. Due to its potential for malignization, exeresis is often required. Lesions located in the scalp are challenging to surgeons because of the anatomical characteristics of this body site, namely scarcity and inelasticity of the adjacent skin. In the present report, the authors describe a case of excision of a nevus sebaceous of Jadassohn located in the scalp, using a bilateral rotation flap a very straightforward and versatile technique, excellent for reconstructing difficult topographies such as the scalp for the closure of the surgical wound.
RESUMO
Abstract Lupus tumidus is considered a rare subtype of chronic cutaneous lupus erythematosus, characterized by erythema and bright urticarial erythematous-violaceous lesions that leave no scars after regression. Histopathology reveals perivascular and periannexal lymphohistiocytic infiltrates in the papillary and reticular dermis and interstitial mucin deposition. Treatment is based on photoprotection, topical corticosteroids and antimalarials. We report two cases of lupus tumidus, which deserve attention for their low frequency in the literature, in addition to their relevance as a differential diagnosis among dermatologic disorders.
