An Unusual Trifecta: Dermatillomania, Psoriasis, & MRSA in a Rare Case of Primary Cutaneous Gamma/Delta T-Cell Lymphoma

Primary cutaneous gamma/delta T-cell lymphoma (PCγδTCL) is one of twelve known cutaneous T-cell lymphoma (CTCL) rare subtypes comprising of less than 1-2% of all cutaneous lymphomas. These subtypes may have either an indolent or aggressive clinical course, or may be co-existent with other dermatological, infectious, or psychiatric conditions. Based on our literature review, we were unable to find documented cases involving all three aspects of possible co-existing conditions in one patient. We present case of a 61-year-old Caucasian male diagnosed with biopsy-confirmed primary cutaneous gamma/delta T-cell lymphoma with dermatillomania, psoriasis, and MRSA.
