Abstract

Abstract:Primary cutaneous T-cell lymphoma is distinct from nodal T-cell lymphoma clinically and pathologically. Recently, primary cutaneous follicular helper T-cell lymphoma (PC-TFHL) has been described as a peripheral T-cell lymphoma with T-follicular helper (TFH) cell phenotype. PC-TFHL usually presents as multiple plaques and nodules of skin with an indolent clinical course, but without association with Epstein–Barr virus. In this article, we report 2 rare cases of PC-TFHL which are Epstein–Barr virus–positive and with an aggressive clinical course. We discuss the challenges in the differential diagnoses, particularly with primary cutaneous extranodal NK/T-cell lymphoma, and nodal T-cell lymphoma of TFH origin with secondary cutaneous involvement.
