title: Sebaceous adenoma in the retromolar region: report of a case with a review of the English literature.
abstract: This paper reports a rare case of sebaceous adenoma on the right mandibular retromolar mucosa in a 73-year-old Japanese man, with a review of the English literature of sebaceous adenomas of salivary gland origin. A painless and yellowish polypoid lesion in the retromolar mucosa was histologically a relatively well-circumscribed neoplastic mass composed of well-differentiated sebaceous cells with cystic and duct-like structures, and was considered to be a true sebaceous gland neoplasm arising from the minor salivary gland tissue.
