Abstract
Papillary cystadenocarcinoma is a rare malignant neoplasm of the salivary gland, characterized by noticeable cystic and solid areas with papillary endophytic projections. These tumours lack features that characterize cystic variants of several more common salivary gland carcinomas. It was first described in 1991 by World Health Organization as a separate entity and cystadenocarcinoma with or without papillary component in the AFIP classification. Most of these tumours occurred in the major salivary glands followed by minor salivary glands. Cystadenocarcinoma is the malignant counterpart of cystadenoma. We report a case of papillary cystadenocarcinoma of parotid. A 40-year-old lady presented with gradually progressive swelling below the right ear associated with occasional pain. Clinical and radiological features suggested benign neoplasm. Right lobe superficial parotidectomy was performed. The histopathologic diagnosis showed papillary cystadenocarinoma of the parotid gland. Histologic confirmation of stromal invasion is required to differentiate it from the benign lesion. Conservative wide local surgical excision is the treatment of choice.
