Abstract
The authors reported a rare case of papillary cystadenoma of the parotid gland. The patient, a girl of twelve years, had taken notice of the swelling on the right parotid region two years before, but she did not take medical treatment, by want of subjective symptom. She visited the authors' clinic, as the tumor had enlarged for ten days. The tumor was grape-sized, of consistency similar in cartilage, uneven, and partially adherent to the skin and not movable on its basis. The tumor was removed by operation, a part of it was cystic and kept the clear light yellow fluid, but other part was uneven and firmly fixed to the parotid gland. Histological examination revealed it was papillary cystadenoma which had malignant nature latently, because of the existence of cell infiltration and proliferation in the stroma. Postoperatively radiation therapy with 60Co was added. Four monthes after the operation the parotid gland and duct were sialographically certified as normal. The authors are keeping the patient under observation.
