耳下腺腫瘍を思わせた耳下部石灰化上皮腫の1例

抄録

We experienced a case in a 15-year-old girl of calcifying epithelioma which developed subcutaneously in the right parotid region. About 4 months before she visited us, she noted the presence of a tumor in the right parotid region. It grew gradually. Results of examinations (echography, RI-scintigraphy, target CT-sialography and smear by FNA) indicated that she had a parotid tumor arising from the superficial layer of the right parotid gland. However, from the operative and histopathological findings she was diagnosed as having a calcifying epithelioma. The epithelioma has not recurred for 1 1/2 years.
