抄録

Hemangioma is common in the region of the head and neck, especially in the tongue, lip and buccal mucosa. But the hemangioma which includes the phlebolith is relatively rare. The authors reported two such cases.<BR>Case 1 was a 17-year-old man who visited our clinic complaining of a swelling of the left cheek. The swelling had been there since his birth, and it had gradually increased in size with general bodily growth. He was diagnosed as a buccal hemangioma with phleboliths.<BR>The tumor occupied the entire left cheek. Subtotal extirpation was performed and a multiple ligature suture was done to the residual tumor. The postoperative histological diagnosis was cavernous hemangioma with phleboliths. Scanning electron microscopic findings of the phlebolith revealed a concentrical lamellar structure. Analyses of the phleboliths by means of infrared spectrometry and X-ray diffraction identified calcium phosphate as the component of the phleboliths, and suggested the existence of calcium carbonate.<BR>Case 2 was a 37-year-old woman who had noticed the tumor on her left cheek 16 years before and it was excised at that time. But it recurred one month later and grew slowly.<BR>Total resection of the tumor was performed in our clinic. The resected tumor was walnutsized and well-capusulated one. The postoperative histological diagnosis was cavernous hemangioma. Thrombi and phleboliths were also observed within the tumor.
