Malignant Neoplasm of the Temporal Bone: Radical Temporal Bone Resection as Primary Approach
Introduction: Malignant neoplasms of the external ear and temporal bone are rare conditions, and the squamous cell carcinoma (SCC) is the most frequent.
Objective: The study aims to present a case of SCC of the external ear with temporal bone invasion, diagnosed at an advanced stage.
Resumed report: A 60-year-old man presented in the otorhinolaryngology and head and neck departments of a tertiary hospital, with a history of bilateral hearing loss, chronic otorrhea, and recent left otalgia. Otoscopic examination of the left ear showed stenosis of the external auditory canal; purulent discharge; and a hardened, vegetating, ulcerated lesion, affecting the left tragus and posterior auricular region. The biopsy of the lesion showed SCC. Imaging studies showed invasion of the temporal bone and tumor contact with the sigmoid sinus. Surgical approach was chosen as the primary treatment, associated with adjuvant radiotherapy and chemotherapy.
Conclusion: Because it is rare and its symptoms are confused with other benign diseases, the suspicion of malignancy is extremely important for the early diagnosis and treatment.
