A 42-year-old male patient, alcoholic, presented showing signs of tumors in the neck and around the shoulders, scaly, erythematous-violaceous lesions and some bullous lesions in sun-exposed areas of upper and lower limbs. Based on clinical features, laboratory tests and imaging studies we have established the diagnosis of pellagra associated with benign symmetrical lipomatosis, both justified by chronic alcoholism. Treated with intravenous B-complex and oriented about the importance of alcohol withdrawal, the patient showed complete remission of skin lesions, but with no change in the lipomatosis.

A neurofibroma is a hamartomatous proliferation of neuromesenchymal origin. It may be found in combination with neurofibromatosis or in the form of a solitary tumor. Clinical presentation as a solitary subungual tumor is very rare. Neurofibroma is more common in females and surgery is the treatment of choice. The present paper reports the case of a male patient with a subungual tumor on his toe. Biopsy and immunohistochemistry findings were compatible with a neurofibroma. To date, fewer than ten cases of subungual neurofibromas unassociated with von Recklinghausen's disease have been documented, this being the first case to be reported in Brazil and the only report worldwide to have described this condition in a male patient.
