Lennert's lymphoma presenting as prurigo nodularis

Lennert's lymphoma is a peripheral T-cell lymphoma that only rarely involves the skin. We present the case of a forty-two-year-old man who experienced severe pruritus for ten months. He was repeatedly diagnosed as having neurodermatitis and prurigo nodularis before subtle hematologic clues suggested, and subsequent examination of bone and lymph node biopsy specimens confirmed, the diagnosis of Lennert's lymphoma. This report describes the case and presents a brief review of Lennert's lymphoma.
