Abstract

Malignancy of the middle ear is rare and its estimated incidence is 0.18 cases per million people in the US, with its most common type being squamous cell carcinoma. Squamous cell carcinoma in situ is thought to be a precursor to squamous cell carcinoma, which is extremely rare in the middle ear. The pathology reports of squamous cell carcinoma have not been well-characterized as it has not been reported to date in Korea. Here, we report a case of squamous cell carcinoma in situ of the middle ear in a 66-year-old man, who presented with otorrhea and tympanic membrane perforation.
