Aural Polyp or Temporal Bone Carcinoma: Lesson to Learn

Temporal bone carcinoma is a rare malignant tumor of the head and neck region. Its clinical presentations can mimic benign ear diseases, leading to inaccurate diagnosis and substandard management. We present the case of a 53-year-old female with a three-month history of progressive right otalgia, otorrhea, and hearing loss. Otoscopic examination revealed a mass occupying the right external auditory canal. However, the lesion was presumed to be an aural polyp by several clinicians previously. Multiple courses of oral antibiotics had been prescribed before she was referred to our clinic for the non-resolving aural polyp. Imaging studies showed an external auditory canal soft tissue mass with extradural and parotid extension. The mass was biopsied, and the result was reported as squamous cell carcinoma of the temporal bone. The patient was advised for a total temporal bone resection and parotidectomy; however, she declined the surgical intervention. Within a month, the tumor had metastasized to her lung, liver, and vertebral bodies. She was referred to the Oncology team for palliative chemo-radiotherapy. Temporal bone malignancy must be considered as a differential diagnosis in a middle-aged or elderly patient with a non-resolving aural polyp without a chronic discharging ear. Imaging studies and histopathological evaluation should be prompted to ascertain the diagnosis. Repeated course of oral antibiotic will delay treatment and subsequently may lead to poor prognosis.
