RESUMEN
Abstract: Periungual basal cell carcinoma is rare and needs to be differentiated from other common diseases that affect this region. Several factors are associated with the development of this tumor, and sun damage seems to play an important role in its pathogenesis. Dermoscopy of clinically indolent lesions on the nail unit can shorten the diagnostic process and avoid destructive treatment and functional damage.

Lucio's phenomenon represents a serious cutaneous necrotizing reaction, which can occur with Lucio's leprosy and also in other forms of lepromatous leprosy. The authors discuss the case of a 63-year-old male patient presenting with ulcers and necrotic cutaneous lesions on the limbs, torso and face, associated with recurring sinusitis, hoarseness and a weight loss of 25 kilos over the last year. Bacilloscopy of intradermal scrapings showed a bacilloscopic index of 5 and the histopathological findings were compatible with the diagnosis of Lucio's phenomenon. The chosen treatment was exclusively multibacillary multidrug therapy, resulting in important dermatological improvement after one month of therapy. The authors present an impressive case of Lucio's phenomenon with an exceptional response to treatment exclusively with multibacillary multidrug therapy.
O fenômeno de Lúcio representa uma reação cutânea necrosante grave que pode ocorrer na hanseníase de Lúcio e em outras formas de hanseníase virchowiana. Os autores relatam o caso de um paciente masculino de 63 anos de idade apresentando há um ano lesões ulceronecróticas nos membros, lóbulos auriculares e tronco, associadas a sinusite de repetição, rouquidão e perda ponderal de 25 kg. A baciloscopia de raspado intradérmico mostrou índice baciloscópico de 5 e o exame histopatologico foi compatível com fenômeno de Lúcio. O tratamento instituído foi exclusivamente com poliquimioterapia multibacilar (PQT-MB), havendo melhora importante do quadro cutâneo após um mês de tratamento. Os autores apresentam um caso exuberante de fenômeno de Lúcio que obteve excelente resposta ao tratamento somente com PQT-MB.
