Cutaneous involvement by this virus is rare and occurs in significantly immunocompromised hosts, with a poor prognosis. Skin ulcers may represent the first sign of systemic infection by cytomegalovirus in these patients. Herein, a case of a systemic infection by Cytomegalovirus presenting as genital and oral ulce...

Melanoma associated with congenital intermediate common blue nevus of the scalp...
Ribeiro,Camila Sampaio; Serpa,Sergio S.; Sousa,Maria Auxiliadora Jeunon; Jeunon,ThiagoAbstract: Melanomas can arise either de novo (70%) or from pre-existing melanocytic lesions (30%). Of the latter, most cases arise at the dermoepidermal junction from small congenital or acquired non-blue nevi while only a few arise from blue nevi, notably the cellular subtype and less commonly the common (dendritic) type. Melanomas that arise from blue nevi usually occur on the scalp with greater frequency, as...

Hidradenite supurativa tratada com infliximabe
Obadia,Daniel Lago; Daxbacher,Egon Luiz Rodrigues; Jeunon,Thiago; Gripp,Alexandre CarlosA hidradenite supurativa é doença inflamatória de difícil tratamento. Recentemente, a terapia anti-TNF alfa, com anticorpos monoclonais ("terapia biológica"), tem sido apontada como uma alternativa. No entanto, ensaios clínicos avaliando a eficácia destas drogas na hidradenite supurativa, ainda não foram publicados. Apresentamos um caso no qual o uso do infliximabe não resultou em melhora clínica expressiva.
