C86.3

Approximate Synonyms

• Lymphoma, subcutaneous panniculitis-like t-cell

Clinical Information

• A cytotoxic primary cutaneous t-cell lymphoma. Recent studies suggest there are at least two groups of subcutaneous panniculitis-like t-cell lymphomas, each with distinct histologic features, immunophenotypic profile, and prognosis. One group has an alpha/beta, cd8 positive phenotype, involves only subcutaneous tissues, and usually has an indolent clinical course. The second group has a gamma/delta phenotype, is cd8 negative, often co-expresses cd56, is not confined to the subcutaneous tissues, and usually has a poor prognosis. In the recent who-eortc classification, the term subcutaneous panniculitis-like t-cell lymphoma is reserved for cases with an alpha/beta, cd8 positive phenotype. Cases with a gamma/delta phenotype are included in the group of cutaneous gamma/delta t-cell lymphomas.
