Intravascular papillary endothelial hyperplasia (IPEH), or Masson’s tumor, is a rare and benign proliferation of endothelial cells typically of vascular origin. Common locations of Masson’s tumor include the head, neck, orbit, lip, pharynx, and mandible. It is typically seen in middle-aged adult life and females. Possible differential diagnoses include hemangioma, benign vascular formation, angiosarcoma, and neurofibromatosis. The exact pathophysiology of Masson’s tumor is currently unknown. We present the case of a middle-aged 47-year-old male with a pure type of Masson’s tumor presenting with pedunculated, malleable lesions across the posterior scalp and circumferential neck, on the pinna of the right ear, and within the right external auditory meatus. The lesions within the right external auditory meatus caused conductive hearing loss. The plan is a complete surgical excision without wide margins. The patient was referred to an ear, nose, and throat (ENT) surgeon due to the complicated location of the lesion within the external auditory meatus. This case serves as a differential diagnosis of conductive hearing loss complicated by Masson's tumor.
