Phleboliths were found in the cheek of one patient and in the submandibular region of another. Including these two cases, 50 cases of phleboliths in the region of the head and neck have been reported from 1930 to 1972.Our first patient was a 7-year-old child who had a few nodules in the right cheek. There were a few palpable nodules the size of a rice grain and some fluctuation. Phleboliths of the cheek were suspected. The postoperative histological diagnosis was phlebolithiasis in a buccal hemangioma.The second patient was a 70-year-old woman with a painless submandibular tumor on the left side, which she had first noted about two weeks earlier. Many calcifications seemed to be dispersed at random throughout an area corresponding to the tumor on roentgenography, so salivary calculi of the submandibular gland were suspected at first. However, the submandibular gland seemed to be compressed anteriorly by the tumor and no narrowing or obstruction of the duct was seen on sialographic examination. The tumor in the left submandibular region was removed surgically, and microscopic examination revealed a phlebolithiasis which originated at the base of a cavernous hemangioma.
