Popis: | BACKGROUND: Mucinous cystadenocarcinoma of the salivary gland is a rare entity. Review of the literature from 1991 to 1999 revealed no previous reports on its cytologic features. CASE: A 25-year-old man had a slowly growing, painless mass in the left parotid gland. Fine needle aspiration biopsy, performed prior to surgical excision, showed clusters of minimally atypical epithelial cells in which occasional vacuolated cells containing mucin could be seen. Pathologic evaluation of the resected parotid mass showed it to be a mucinous cystadenocarcinoma. CONCLUSION: The cytologic differential diagnosis of mucinous cystadenocarcinoma is with low grade mucoepidermoid carcinoma and with mucinous adenocarcinoma. Mucinous cystadenocarcinoma must be cystic; cysts may be present in low grade mucoepidermoid carcinoma, but their size and prominence varies. Mucinous adenocarcinoma is not cystic but gelatinous. Nuclei are bland in both mucinous cystadenocarcinoma and low grade mucoepidermoid carcinoma but are atypical in mucinous adenocarcinoma. There is no squamous differentiation in either mucinous cystadenocarcinoma or mucinous adenocarcinoma, but it is subtle in low grade mucoepidermoid carcinomas. Mucinous cystadenocarcinoma should be considered a potential candidate in the differential diagnosis of mucinous lesions that can occur in the salivary gland. |
