Papillary mucous cystadenoma of parotid gland

Cystadenomas are rare benign salivary gland tumours characterised by prominent epithelium-lined papillary projections into the cystic spaces. Cystadenoma accounts for 2% of all salivary gland tumors, occurring most commonly in major salivary glands. Histopathologically there are two variants, papillary and mucinous variant. However very few cases are being reported in literature. We report a case of papillary cystadenoma occuring in parotid gland in a 28 year old male patient. Clinically, it presents as a soft, fluctuant, sessile and non-tender swelling measuring about 4×3.5 cm in diameter. Excisional biopsy was performed. The histopathological features were characteristic of papillary cystadenoma. This article highlights its clinical and histopathological features along with review of literature.
