Cutaneous lymphomas with a panniculitic presentation.

Abstract

Subcutaneous panniculitis-like T-cell lymphoma and primary cutaneous gamma/delta T-cell lymphoma are the two most common types of cutaneous T-cell lymphoma presenting with panniculitis-like lesions. In this article the characteristic clinical, histological and immunophenotypical features of these conditions are reviewed and criteria to differentiate these tumors from other benign and malignant lymphoproliferations presenting with panniculitis-like lesions are discussed.
