This report describes a case of papillary cystadenocarcinoma of the tongue. Papillary cystadenocacinoma is a rare disease newly added to the WHO classification of salivary gland neoplasms in 1991. And it is a malignant tumor with a papillary growth pattern in a cystic structure.<BR>The patient was a 50-year-old woman. Clinically, a minor salivary gland tumor of the tongue was the diagnosis for a small mass on the right-side lingual edge, so a partial excision of the tongue was performed. The histopathological diagnosis was papillary cystadenocacinoma. Postoperative external irradiation (total 55.6Gy) was performed to the perif ocal tissue, because infiltrative growth and lymph vessel invasion were found in the circumference. Present in postoperative about 1 year, the opinion which suspects recurrence and metastasis is not found.<BR>We report on the therapy and prognosis with a literary consideration.
