Incipient Warthin tumor of intraparotid lymph node in a patient with squamous cell carcinoma of the external auditory canal: An incidental finding

Deepak Pandiar et al. Natl J Maxillofac Surg. 2020 Jan-Jun.

Abstract

The occurrence of intranodal salivary gland neoplasm is uncommon; squamous cell carcinoma (SCC) of the external auditory canal (EAC) is another rare occurrence. Clinically, SCC of EAC presents with symptoms similar to other benign otologic conditions. A case of Stage I SCC in EAC region is presented here in a 60-year-old male patient with incidental intranodal Warthin tumor along with the histological differential diagnosis. The patient is being followed up. There is no evidence of recurrence 1 year and 11 months after surgery.

Keywords: External auditory canal; Stage I; Warthin tumor; squamous cell carcinoma.
