Sclerosing Polycystic Adenosis of the Parotid Gland: A Case Report and Literature Review

TL;DR

A rare benign salivary gland condition called sclerosing polycystic adenosis was diagnosed and successfully treated through surgery in a 44-year-old woman.

Contribution

This case report adds to the limited literature on sclerosing polycystic adenosis and highlights its diagnostic challenges and successful treatment.

Findings

SPA was confirmed through histopathological analysis after initial suspicion of a pleomorphic adenoma.

Complete surgical excision resulted in a cure, with no malignant features observed.

The case emphasizes the importance of considering SPA in the differential diagnosis of parotid gland masses.

Abstract

Sclerosing polycystic adenosis (SPA) is a rare benign salivary gland lesion that resembles both benign and malignant tumors, complicating diagnosis. We present the case of a 44-year-old woman with progressive right lateral facial swelling. MRI suggested a pleomorphic adenoma and initial parotidectomy was followed by total excision based on frozen section results. Final histopathological analysis confirmed SPA, with characteristic abnormal glandular architecture in a sclerotic stroma and absence of malignant features. Complete surgical excision was curative. This case underscores the importance of considering SPA in the differential diagnosis of parotid masses.
