Posttransplantation primary cutaneous T‐cell lymphomas (PT‐CTCL) are a rare complication of sustained immunosuppression in the posttransplant setting. When present, PT‐CTCLs are typically EBV− and exhibit features of mycosis fungoides/Sézary syndrome or CD30+ lymphoproliferative disorders. We present a case of a 75‐year‐old individual who developed skin lesions 30 years after liver transplantation. Pathologic evaluation of the skin biopsy revealed involvement by a clonal, EBV+ T‐cell population of gamma/delta lineage with no evidence of systemic disease. Comprehensive genomic profiling was performed, confirming focal one‐copy loss of 6q23.3, altogether consistent with the extremely rare and unusual diagnosis of primary cutaneous EBV+ extranodal NK/T‐cell lymphoma of gamma/delta T‐cell lineage in the posttransplantation setting.
