Abstract

Pleomorphic adenoma (PA) of external auditory canal is an extremely rare benign neoplasm of uncertain origin with only few reported cases in the literature. It’s always challenging to diagnose pleomorphic adenoma of external auditory canal due to its rarity, unusual location as well as nonspecific symptoms mimicking more prevalent benign and malignant lesion of this site. Due to its premalignant nature and chances of recurrence, this case highlights the importance of Pleomorphic Adenoma as differential diagnosis in patient presenting with external auditory canal masses and necessity of complete surgical excision. This case report of 52 years male describes the clinical presentation, histopathological features and immunohistochemical findings of pleomorphic Adenoma of external auditory canal with review of literature emphasizing the diagnostic and therapeutic challenges associated with neoplasm.
