頭頸部領域に生じた石灰化上皮腫6症例の臨床病理学的検討 Clinicopathological study of calcifying epithelioma in the head and neck region
Calcifying epithelioma is a benign tumor derived from hair matrix cells. We evaluated the clinicopathological characteristics of 6 calcifying epitheliomas between January 1994 and March 2003.<BR>Four patients were male, and 2 were female. They ranged in age from 13 to 29 years (mean, 22.8 years). Symptoms comprised tumor formation in 4 patients, and tumor formation with redness of the overlying skin in 2 patients, including 1 with vesicle formation.<BR>Clinically, this tumor was easily diagnosed in typical cases. In cases with inflammation or vesicle formation, fineneedle-aspiration cytological examination was helpful for diagnosis.<BR>Histopathologically, the tumor consisted of basophilic cells and shadow cells. In addition, calcification, bone formation, and foreign body giant cells were also observed in the tumor.
