Sebaceous carcinoma is a rare cutaneous malignancy of sebaceous glands, but it is up to 25-fold more common in immunosuppressed individuals. In this narrative review, we examine the current literature on the pathogenesis, incidence, risk factors, prognosis, treatment, and surveillance of sebaceous carcinoma in immunosuppression and highlight practical considerations for providers who care for these patients. Increased incidence may be related to decreased immune surveillance, susceptibility to an unknown viral trigger, microsatellite instability, immunosuppressive medications, and unmasking of occult Muir-Torre Syndrome.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections.
