A Rare Case Report of Mucinous Cystadenoma with Immunohistochemical Analysis and Review of Literature

Abstract

Cystadenomas are rare salivary gland tumours characterised by prominent epithelium-lined papillary projections into the cystic spaces. A 37 year-old female, presented with a swelling on the right side of the hard palate. Clinically, the swelling was soft, fluctuant, sessile and non-tender measuring 2.5 9 2 cm in diameter. Excisional biopsy was performed. The histopathological and immunohistochemical features were characteristic of mucinous cystadenoma. There has been no recurrence over a 2-year follow up period. The article highlights its clinical, histopathological, immunohistochemical features and differential diagnosis along with review of literature. Cystadenoma of the palate is rare, papillary variety being more common than mucinous with very few cases reported in literature.

Papillary cystadenoma of the parotid gland: A case report

“…Recurrence is seldom seen, with more tumors recurring in major salivary glands than in minor ones. Inadequate removal due to an incomplete capsule or tumor cell infiltration of the parotid gland is probably responsible for recurrence[13,18]. Although cystadenoma of the salivary gland is a benign tumor, postoperative malignant transformation has been reported[19].…”
