Papillary cystadenoma lymphomatosum is a slow-growing, encapsulated tumor which is usually developed in the salivary glands. It consists of papillary masses of epithelia and an abundance of lymphoid tissue.
A case of papillary cystadenoma lymphomatosum is presented. A seventy-year-old woman had had a slow-growing tumor inthe right parotid region for three years. Sialography showed no evidence of neoplasm within the parotid gland. The tumor was surgically removed together with the lower portion of the parotid gland to which the tumor had been tightly attached. Histological examination revealed that the tumor was papillary cystadenome lymphomatosum and that there was a capsule between the tumor and the gland, which separated the two structures clearly.
