This document describes an 88-year-old male patient who presented with a swelling on his right ear pinna for one year with discharge for the past 10 days. On examination, a 5 cm proliferative growth was seen on the right pinna. Differential diagnoses included cutaneous horn, verrucous hyperplasia, verrucous carcinoma, and invasive squamous cell carcinoma. The patient underwent wide local excision of the lesion under general anesthesia. Histopathology revealed squamous cell hyperplasia without evidence of invasive cancer.
