Abstract: The Whartin Tumor is the second most frequent tumor of the parotid gland following pleomorphic adenoma. Among the Whartin tumors, Metaplastic Whartin Tumor (MWT) is rare. In case of a MWT, histo-pathological replacement of oncosytic cells by squamous cells, ruptured epidermoid and lymphoe-pithelial cystic areas, a large necrosis area, fibrosis and granuloma formation may be seen. MWT may display similar clinical characteristics as the malign parotid tumor that causes sialadenitis, abscess formation, skin ulceration, and facial paralysis. Although the histopathogenesis of Metaplastic Whartin Tumors is not exactly known, it is postulated that the histo-pathological processes caused by trauma, infection, or radiotherapy have a role in the formation of these tumors. This case study presents a 48-year-old female patient with a complaint of panicula before her left ear persisting for 5 months. Following a superfacial parotidectomy carried out 3 weeks after the fineneedle aspiration biopsy (FNAB), her pathological assessment was found to be in line with Metaplastic Whartin Tumor. Our case study presents the case of a Metaplastic Whartin Tumor case with a review of literature on the subject, accompanied by radiological and histological analyses.
