Most salivary gland hemangiomas have involved the parotid gland, and cavernous hemangioma of the submandibular gland is rare. We have treated a cavernous hemangioma, which had several phleboliths in the right submandibular gland.
A 46-year-old female was referred to our clinic with a swelling in the right submandibular triangle. The clinical features appear to be hemangioma of the submandibular gland. Computed tomography, ultrasonography and magnetic resonance imaging were useful in the diagnosis. Under general anesthesia, the tumor was removed surgically, and the histopathological diagnosis was cavernous hemangioma with several phleboliths. Since surgery, the patient has shown a favorable prognosis and there has not been any sign of recurrence.
Including our case, 25 cases of hemangioma of the submandibular gland have been reported between 1960 and 2005 in Japan. Patient ages range from 6 to 70 years with an average age of 31.4 years. There were 12 males and 13 females and 80％ (20/25) of the cases had cavernous hemangioma. Phleboliths were found in about 70％ (17/25). Most of the cases (96％, 24/25) were treated surgically.
Key words : cavernous hemangioma, submandibular gland, phleboliths
