Abstract
|
|
|
|
Malignancy of the middle ear is rare and its incidence is 0.18 cases per million people, with its most common type being squamous cell carcinoma. The radiologic, surgical findings, and pathology reports has not been well characterized due to its low incidence. Squamous cell carcinoma in situ of the middle ear is even more so. Here, we report a case of a 69-year-old man who developed squamous cell carcinoma of middle ear 19 months after wide excision for squamous cell carcinoma in situ. The patient received concurrent chemoradiation therapy after revision operation and being evaluated as a stable disease for 30-months follow-up. This case represents the first reported occurrence of squamous cell carcinoma of the middle ear after wide excision for squamous cell carcinoma in situ. A diagnosis of squamous cell carcinoma should be considered in a patient with squamous cell carcinoma in situ of middle ear even after surgery.
