ABSTRACT
Abstract Merkel cell carcinoma is an uncommon neuroendocrine carcinoma with a rising incidence and an aggressive behavior. It predominantly occurs in older patients, with onset occurring at a mean age of 75-80 years. Recognized risk factors are ultraviolet sunlight exposure, immunosuppression, and, more recently, Merkel cell polyomavirus. We report a case of Merkel cell carcinoma in a young HIV positive patient with Merkel Cell polyomavirus detected in the tumor.

Parafinoma decorre da implantação de óleo mineral na pele, sendo caracterizado por reação inflamatória do tipo corpo estranho com período de latência variável. As lesões iniciais são nódulos endurecidos, que podem ulcerar, fistulizar ou necrosar. Esta técnica foi muito utilizada para fins estéticos no século XX, não sendo mais realizada por médicos. Contudo, ainda é empregada por profissionais não médicos ou pelos próprios pacientes, principalmente na região genital, para melhoria da prática sexual. Relata-se caso de implante de óleo mineral no pênis, realizado por profissional não médico para fins estéticos, que evoluiu com necrose após três anos.
Paraffinoma results from the implantation of mineral oil in the skin, being characterized by inflammatory reaction of foreign body type, with variable latency period. Initial lesions consist of hardened nodules, which can ulcerate, fistulate or necrose. This technique was widely used for aesthetic purposes in the 20th century, and is no longer performed by physicians. However, it is still used by non-medical professionals or by the patients themselves, mainly in the genital region, aimed at improving sexual activity. This paper reports a case of implantation of mineral oil in the penis, performed by a non-medical professional, for aesthetic purposes that evolved with necrosis after three years.
