Sebaceous adenoma of the salivary gland is a rare tumor comprising 0.1% of all salivary gland neoplasms and less than 0.5% of salivary adenomas. Histologically, sebaceous adenomas are benign neoplasms consisting of sebaceous cells arranged in nests forming acinar and duct-like structures. Oncocytic metaplasia may also occur in some areas. We describe a case of sebaceous adenoma in the submandibular gland. Under a presumptive diagnosis of sialadenitis/sialolithiasis, the patient was administered multiple courses of antibiotics; however, these were not effective. Excisional biopsy resulted in a diagnosis of sebaceous adenoma. A 1-year follow-up showed no recurrence. (J Oral Sci 51, 641-644, 2009)
