Abstract: | A rare case of epithelial myoepithelial carcinoma of the parotid gland, which occurred in a child, is reported. An 8 year old boy presented with swelling of the right parotid gland. He underwent total parotidectomy followed by irradiation for a parotid gland tumor. Three years after the operation, a recurrent tumor invading the base of the skull and the brain and metastases in the lung were noted. The patient expired in spite of extirpation of the intracranial recurrent tumor. The resected tumor showed a character istic histologic feature:double -layered tubular structures composed of inner dark cells (epithelial cells) and outer clear cells (myoepithelial cells). This patient may be the youngest one with the epithelial-myoepithelial carcinoma reported in the literature. Acta Pathol Jpn 42: 358–363, 1992. |
