It is seen in the elderly population and is more common in males. It is a benign tumor and has strong association with smoking. Malignant transformation is very rare in Warthin\u2019s tumor and can involve both the lymphoid, as well as epithelial components. Here we present a rare case of malignant transformation in Warthin\u2019s tumor in a female patient. She presented with an infra-auricular swelling on right side for 1 year with rapid increase in size of the swelling since last 3 months. Imaging studies showed possibility of a benign parotid tumor. Fine needle aspiration cytology showed features of Warthin\u2019s tumor. Histopathology and Immunohistochemistry confirmed the diagnosis of malignant transformation of Warthin\u2019s tumor to adenocarcinoma.<\/jats:p>","DOI":"10.4103\/jpbs.jpbs_1543_25","type":"journal-article","created":{"date-parts":[[2026,1,23]],"date-time":"2026-01-23T09:01:19Z","timestamp":1769158879000},"page":"S263-S265","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Adenocarcinoma
