Objective: Adenocarcinoma of the middle ear is a rare entity that must be distinguished from other adenomatous tumors of the temporal bone. We present the first patient of an intestinal-type adenocarcinoma originating from the middle ear. Patients: A 58-year-old woman presented with an 8-year history of left otorrhea. Her middle ear effusions were quite thick and gummy. She underwent eight sets of pressure-equalization tubes within 3 years. In 2011, her physical examination identified a middle ear mass, and she underwent mastoidectomy. A middle ear adenoma was resected. She underwent an additional three mastoidectomies for recurrence, with pathology from the 4th mastoidectomy revealing a diagnosis of adenocarcinoma. Imaging, at that time, showed an extensive temporal bone and Eustachian tube tumor. Interventions: She underwent a left subtotal temporal bone resection, parotidectomy, infratemporal fossa resection, dural resection, and microvascular free flap reconstruction followed by postoperative proton beam radiotherapy. Main Outcome Measures: The final pathology report revealed intestinal-type adenocarcinoma. Results: Treatment was successful and the patient remains disease free 4 years later. Conclusion: This is the first report of an intestinal-type adenocarcinoma of the middle ear and temporal bone. This patient also illustrates the difficulty of accurate histologic diagnosis of adenomatous tumors of the middle ear.
