Hemangioma is a dysontogenic malformation which appears as a tumor-like lesion predisposing head and neck areas.<BR>This report represents the detailed description of a case of cavernous hemangioma with phleboliths adjacent to the right submandibular gland.<BR>A 16 year-old Japanese girl was referred to the clinic with a chief complaint of a submandibular swelling which enlarged during and after meals.The salivary flow from the right submandibular gland was rather lower than that of the opposite side. Roentogenograms showed several radiopaque masses at the right submandibular area suggestive of sialoliths. However, sialograms indicated that these masses were not construed as submandibular gland. Moreover the swelling was fluctuant and blood could be aspirated by puncturing.<BR>Under the diagnosis of hemangioma, the tumor was extirpated, which was about 4 cm in diameter and histologically diagnosed as a cavernous hemangioma with several phleboliths. Phleboliths mostly consisted of hydroxyapatite by X-ray diffraction analysis.<BR>The clinical symptoms disappeared and there is no recurrent.
