Primary Cutaneous Gamma/Delta T-cell Lymphoma and Hemophagocytic Lymphohistiocytosis Associated With AIDS

Primary cutaneous gamma delta T-cell lymphoma (PCGD-TCL) is a rare lymphoma that makes up less than 1% of all cutaneous T-cell lymphomas. Patients with PCGD-TCL typically present with rapidly progressing plaques and ulceronecrotic nodules most frequently located on extremities without lymph node or bone marrow involvement. The overall prognosis is poor with a median overall survival of approximately 15 months. This case highlights a patient with concomitant PCGD-TCL, hemophagocytic lymphohistiocytosis, and human immunodeficiency virus-1-acquired immunodeficiency syndrome. There is a paucity of case reports describing PCGD-TCL and there are no evidence-based treatment recommendations. Further studies are needed to optimize strategies to treat patients with these diseases.
