Sebaceous-gland carcinoma can occur alone or as one of the defining features of the Muir-Torre syndrome. Cases occurring below the head and neck are extremely rare. Here we describe the case of a 70-year-old male with Muir-Torre syndrome who had a recurrent sebaceous-gland carcinoma in the left lower extremity that demonstrated (18)F-FDG avidity. An (18)F-FDG-avid lower-extremity sebaceous-gland carcinoma has not been previously reported.

Purpose: To evaluate the prognosis of eyelid sebaceous carcinoma (SeC) in patients with disease stage worse than IIA.
Methods: This retrospective, single-center study included 78 SeC patients. For stage II patients, 1:3 propensity score matching (PSM) was applied between those undergoing orbital exenteration and those receiving eye-sparing treatments.

Purpose: The NAB2::STAT6 fusion is predominantly associated with solitary fibrous tumors (SFTs) and is utilized in diagnosing SFTs through nuclear STAT6 protein overexpression. Recent studies expanded the phenotypic spectrum of NAB2::STAT6 rearranged neoplasms, including adamantinoma-like and teratocarcinosarcoma-like phenotypes. We report a case of a NAB2::STAT6 rearranged epithelial tumor exhibiting sebaceous differentiation in the parotid gland.

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.

Reports of sebaceous carcinoma arising from a pre-existing benign precursor are extremely sparse in the literature. We describe a case in which there was clear transition between sebaceoma and sebaceous carcinoma, with a different pattern of p53 staining in each component.
