Metastasis of Colon Cancer in the External Auditory Meatus

A 68-year-old man came to our ENT emergency room for investigation of a painful swelling of his right ear. He had a history of metastatic adenocarcinoma of the right transverse colon. He was receiving palliative Folfirinox chemotherapy. Clinical examination of the ear revealed a fluctuated, reddened, painful neoplasm at the entrance of the right external auditory meatus, with no other unusual findings. Incision and drainage of the mass ensued. A small amount of putrid matter was secreted. In view of the patient’s history of cancer, we decided to perform a biopsy. Examination of the sample confirmed our suspicion that the mass was a metastasis of the known colon cancer. The superinfection healed within a week after local antibiotic treatment with ciprofloxacin and aureomycin (Figure a). Computed tomography of the petrosal bone (Figure b) showed an 8-mm mass with little uptake of contrast medium and no bony infiltration. The palliative systemic Folfirinox treatment was continued.Distant metastases of colon cancer of this nature (ear) are extremely rare (2%). Biopsy to exclude distant metastasis should always be considered in the event of unclear findings in the head and neck.
