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.

Nevus lipomatosus cutaneous superficialis is an uncommon dermatosis in which the adipose tissue is present ectopically in the dermis.This condition is clinically divided into two variants: classical and solitary.The first is characterized by soft, pedunculated, cerebriform, skin-colored or yellowish papules or nodules, mainly involving the pelvic region.The latter is observed as a solitary or sessile papule. Treatment with surgical excision is usually enough. Nevus lipomatosus cutaneous superficialis may be associated with other conditions such as multiple lipomas, as in our case.
