Unusual cutaneous manifestation of angiocentric T-cell lymphoma: a case report.

Angiocentric T-cell lymphoma may clinically present with a broad variety of cutaneous manifestations, including papules, nodules, and ulcerated tumors, and may mimic cutaneous vasculitis and Wegener granulomatosis. Histologic diagnosis of angiocentric T-cell lymphoma also may present a challenge because of variations in the degree of cellular infiltrate and cellular atypia. The correct diagnosis is critical because of the importance of choosing the correct therapeutic modality-chemotherapy or x-ray radiation. We report a case of angiocentric T-cell lymphoma with extensive necrotic facial ulcers that responded to treatment with fludarabine, cyclophosphamide, and prednisone.
