CONGENITAL SIALOLIPOMA ON THE TONGUE DORSUM: A CASE REPORT

Sialolipoma is a rare benign neoplasm of the salivary glands that was recently described in the literature, and, until now, fewer than 60 cases have been reported. A 9-year-old child presented complaining of tongue injury. Intra-oral examination revealed a pediculus nodulus lesion with fibrous consistence with 15 mm in maximum diameter, located in the posterior dorsum of the tongue. The child’s parents reported that they had noticed the lesion since her birth. An excisional biopsy was performed based on the initial clinical diagnosis of a fibroepithelial polyp. Histologic examination of the lesion showed a benign neoplastic proliferation of adipocytes and also serous and mucous acini, involved with dense connective tissue. The definitive diagnosis was sialolipoma of the tongue dorsum. The patient has had no evidence of recurrence at 1 year of follow-up.
