Masseteric intramuscular cavernous hemangioma

Abstract

Hemangiomas are the most common vascular tumors. Lymphatic, capillary, venous, and arteriovenous malformations make up the majority of vascular malformations. Intramuscular hemangioma (IMH) is a relatively rare benign tumor of vascular origin accounting for less than 1% of all hemangiomas. The possible sites of occurrence in oral cavity are lips, tongue, buccal mucosa, and palate. IMH arises most frequently in the masseter and trapezius muscle. Due to its location, it is often mistaken for a parotid swelling and rarely is an accurate preoperative diagnosis achieved clinically. The intra-masseteric site also creates special problem in terms of proximity to the facial nerve. Despite its benign origin and behavior, it is always of clinical importance to the dental profession and requires appropriate management. This article reports an unusual case of a 19-year-old female patient with IMH involving the buccal mucosa, treated with complete surgical excision.
