# 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.

## Key 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.
