Remarkable Triple Pleomorphic Adenoma Affecting both Parotid and Submandibular Glands

Synchronous pleomorphic adenoma in the infratemporal fossa and contralateral submandibular gland and endoscopic removal

The objective of this article is to elucidate on our experience with the first case reported in the literature of a synchronous presentation of pleomorphic adenoma (PA) in infratemporal fossa as well as the contralateral submandibular gland. PA most commonly arises from the major salivary glands but has also been reported to arise from minor salivary glands in unusual sites such as the nasal septum, main stem bronchus, trachea, lacrimal gland, external auditory canal, etc. However, it seldom involves the infratemporal fossa and extremely few cases are reported in the literature and coexistent contralateral synchronous PA is nowhere reported in literature. The infratemporal fossa tumour posed a diagnostic dilemma and therapeutic challenge because of its concealed location which we dealt successfully with endoscopic sublabial trans maxillary approach.

Synchronous Ipsilateral Pleomorphic Adenomas of Parotid and Submandibular Glands: An Unusual Finding

A rare case of synchronous ipsilateral pleomorphic adenomas (PA) of the left parotid and submandibular glands is reported. Simultaneous multiple PA in major salivary glands are a very rare entity, and merely few cases of ipsilateral synchronous PA involving parotid and submandibular glands are reported in the literature. The case of a 40-year-old female with a six-year history of asymptomatic growing lesion in both left parotid and left submandibular regions is presented. Left superficial parotidectomy and left submandibular gland excision at the same surgery have been performed. The aim of this article is to highlight the importance of an accurate head and neck presurgery examination both clinically and radiologically, keeping in mind the possibility of multiple tumor location.

Synchronous Parotid and Homolateral Submandibular Gland Pleomorphic Adenoma

INTRODUCTION

Pleomorphic adenomas are benign neoplasms of salivary glands. The simultaneous homolateral occurrence of these tumors in salivary glands is exceedingly rare.

CASE REPORT

An adult female presenting to our OPD with the swelling of right-sided preauricular and submandibular regions was diagnosed with the pleomorphic adenoma based on fine needle aspiration cytology. The patient was subjected to the excision of both swellings under general anesthesia. Postoperative facial nerve functions were within normal limits and final histopathology confirmed pleomorphic adenoma involving both the sites. A pertinent detailed literature review of English and non-English studies was indicative of only nine such cases.

CONCLUSION

Simultaneously occurring pleomorphic adenoma involving homolateral parotid and submandibular glands is a rare phenomenon that should be kept in mind when examining the swelling of the unifocal salivary gland.
