ABSTRACT

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.


Paciente masculino, 42 anos, etilista crônico, apresentando quadro de tumorações em região cervical e ao redor dos ombros, lesões eritemato-violáceas, descamativas e algumas lesões bolhosas, nas áreas fotoexpostas dos membros superiores e inferiores. Baseado no quadro clínico e nos exames complementares, foi estabelecido o diagnóstico de pelagra associada à lipomatose simétrica benigna, sendo ambos os quadros justificados pelo etilismo crônico. Tratado com reposição de complexo B intravenoso e orientado quanto à importância da abstinência alcoólica, apresentou remissão completa do quadro cutâneo, porém sem alteração da lipomatose.

ABSTRACT

Neurofibroma é uma proliferação hamartomatosa de origem neuromesenquimal. Pode ser encontrado associado à neurofibromatose ou como tumor solitário, sendo sua apresentação subungueal solitária bastante rara. É mais frequente em pacientes do sexo feminino e a cirurgia é o tratamento de escolha. Relatase um caso de um paciente masculino, com lesão tumoral subungueal no pododáctilo, cuja biópsia e imuno-histoquímica foram compatíveis com neurofibroma. Até a presente data, menos de dez casos sobre neurofibromas subungueais sem associação com doença de Von Recklinhausen foram documentados, sendo este o primeiro caso relatado no Brasil e o único no sexo masculino no mundo.


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.
