Fordyce granules are found in the oral mucosa of up to 80% of adults. However, primary malignant sebaceous tumors of the oral mucosa are exceedingly rare. To our knowledge, only 5 examples of intraoral sebaceous carcinoma have been reported in the literature. This report describes a primary sebaceous carcinoma of the labial mucosa that arose in an area containing numerous Fordyce granules. A brief review of the clinical and histopathologic features of sebaceous carcinoma is also presented.

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.

PRAME (PReferentially expressed Antigen in MElanoma) is a tumor-associated antigen first identified in tumor-reactive T-cell clones derived from a patient with metastatic melanoma. Immunohistochemistry (IHC) for PRAME is useful for diagnostic purposes to support a suspected diagnosis of melanoma. Anecdotally, PRAME has been observed to stain sebaceous units in glands in background skin.

Objectives: This study aimed to characterize the survival of patients with sebaceous carcinoma (SC) of the eyelids according to demographics and other variables.
Methods: Patients with SC of the eyelids from 2004 to 2017 were identified in the National Cancer Database. Demographic and clinical covariates were assessed.
