Panniculitis-like T-cell lymphoma clinically manifested as alopecia.

A 45-year-old women presented with multifocal scalp lesions with the clinical impression of alopecia areata. Histological findings first suggested cytophagic histiocytic panniculitis, although a 'burned-out' panniculitis-like T-cell lymphoma could not be excluded. After a 20-month follow-up period, assessment of the T-cell receptor gamma-chain gene rearrangement verified the diagnosis of subcutaneous panniculitis-like T-cell lymphoma. This case is interesting because of its isolated scalp manifestation as well as its indolent course.
