Sebaceous carcinoma of the oral mucosa: Case report and review of the literature

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.
