Subcutaneous panniculitic-like T-cell lymphoma and other primary cutaneous lymphomas with prominent subcutaneous tissue involvement.
The concept of subcutaneous T-cell lymphoma defines a reduced group of primary cutaneous lymphomas characterized morphologically by a prominent or exclusive subcutaneous tissue involvement. Subcutaneous panniculitic-like T-cell lymphoma is a rare subtype of primary cutaneous T-cell lymphoma clinically mimicking panniculitis. The clinical course is usually protracted with recurrent cutaneous lesions but rarely with early extracutaneous dissemination. The clinical, histopathologic, immunophenotypic, and evolutive features of this heterogeneous and rare group of primary cutaneous lymphomas are reviewed.
