Primary Squamous Cell Carcinoma of Parotid Gland: Common Tumor at an Uncommon Site - A Case Report

Primary squamous cell carcinoma of the parotid gland is a rare aggressive malignancy with a reported incidence of 0.3-1.5 %. We report the case of a 60-year-old man who presented with a swelling in the parotid region. On FNAC, a diagnosis of mucoepidermoid carcinoma was given. However, clinical correlation was advised to rule out squamous cell carcinoma infiltration from oral cavity. Subsequent histopathological examination confirmed that the tumour was squamous cell carcinoma (SCC). As no other primary source could be demonstrated in the patient, a final diagnosis of primary squamous cell carcinoma of parotid was offered. This case is being reported to highlight the occurrence of a rare tumour of the salivary glands about which both the treating physicians and pathologists need to be aware of.
