Keywords:

Objective: To report a case of parotid cholesteatoma and concurrent squamous cell carcinoma of the temporal bone in a 51-year-old woman.
Methods:
Design: Case Report
Setting: Tertiary Government Training Hospital
Patient: One
Results: A 51-year-old woman with a left parotid mass and ipsilateral external auditory canal mass and chronic bilateral otorrhea had parotid biopsy histological features of cholesteatoma and temporal bone imaging suggestive of middle ear cholesteatoma and possible parotid region abscess. She underwent subtotal petrosectomy, mastoid obliteration and excision of the parotid mass. Histopathological examination of the parotid mass was consistent with cholesteatoma but tissue from the middle ear cavity showed well differentiated squamous cell carcinoma.
Conclusion: While cholesteatomas typically arise within the temporal bone, they may occasionally present in atypical or distant sites. In cases where a cholesteatoma demonstrates an unusual location, aggressive behavior, or atypical clinical progression, a high index of suspicion should be maintained for the possibility of an underlying or coexisting temporal bone squamous cell carcinoma.
