Subcutaneous Panniculitis-Like T-Cell Lymphoma

Subcutaneous panniculitis-like T-cell lymphoma is a rare cutaneous T-cell lymphoma (SPTCL) that is characterized by subcutaneous nodules and plaques. The similarity of presentation to that of panniculitis is the reason for the long name. The disease most commonly involves the legs, but can also affect the trunk. It can be differentiated from the cutaneous T-cell lymphomas (e.g., mycosis fungoides and Sézary syndrome) by the fact that the former are cutaneous, and SPTCL is subcutaneous.
