Abstract

Diagnostic pathology in parotid gland (PG) is extremely versatile, due to the diversity, aetiology and histogenesis of PG tumors. Synchronous tumors (either hybrid or collision) are described as two or more distinct neoplasms arising in the same anatomical location, either malignant or benign. We present a case of parotid swelling diagnosed to be Warthin’s tumor (WT) preoperatively which turned out to be a Pleomorphic adenoma – Warthin’s collision tumor. This rare type of collision tumor, was managed successfully by surgery with close follow-up. We aim to enlighten surgeons and pathologists about this rare condition to make them familiar about the difficulties in diagnosis and management of the tumor.
