We describe the case of a 57-year-old man with a 2-year history of intermittent left-sided ear fullness and recurrent cerumen impaction. Otoscopic examination revealed a soft, flesh-colored pedunculated mass on the posterior wall of the left external auditory canal (EAC). Temporal bone computed tomography demonstrated a 6 mm pseudonodular lesion with minimal underlying osteolysis. The patient underwent surgical excision under local anesthesia, and histopathological evaluation confirmed the diagnosis of hidradenoma papilliferum (HP) with no evidence of malignancy. This case highlights the importance of considering HP in the differential diagnosis of EAC tumors, as its presentation is often non-specific. Radiological assessment, complete surgical excision, and histopathological analysis remain essential for accurate diagnosis and effective management.
