Systemic anaplastic large cell lymphoma presenting with cutaneous manifestations in a young man: a case report.

ABSTRACT

Skin lesions can be a sign of internal disease. When they are associated with persisting systemic signs, the possibility of an internal malignancy should always be considered. We describe a 25-year-old man who presented with weight loss, fatigue, subpyrexia, xerostomia and skin rash of 6 months duration. Physical examination showed a dry red skin, most prominent in the face, the palms of the hands and the soles of the feet. Laboratory investigations revealed signs of inflammation and a high level of antinuclear antibodies. Retroperitoneal lymph nodes were visualized on a CT scan of the abdomen. CT-guided biopsy of an abdominal lymph node revealed the presence of an anaplastic large cell lymphoma (ALCL), ALK-positive. A biopsy of the skin showed non-specific signs of inflammation.The patient underwent 8 cycles of chemotherapy according to the CHOP protocol. A complete remission was obtained. Non-Hodgkin lymphoma can indeed be associated with skin lesions. They result from direct invasion by malignant cells or are of paraneoplastic origin, as was the case in this patient.
