Angiocentric T cell lymphoma of the skin presenting as inflammatory nodules of the leg.
We describe two cases of malignant lymphoma presenting as inflammatory nodules of the leg and mimicking panniculitis clinically. In both cases the skin biopsies showed prominent involvement of the subcutaneous tissue by lymphoma cells. In addition, lymphoma cells invaded blood vessels in the dermis or the subcutaneous tissue. One case was characterized by predominantly extravascular and intravascular location of the lymphoma cells, and the other case by the predominantly extravascular and intramural location of lymphoma cells. These histological findings were compatible with those of angiocentric T-cell lymphoma but with some unusual features. Angiocentric T-cell lymphoma of the skin should be listed in the group of diseases which present as inflammatory nodules of the leg.
