Merkel cell carcinoma of the ear

All the consultants agree that, given this patient's history, a common skin tumor like squamous cell or basal cell carcinoma is unlikely. Melanoma or Merkel cell carcinoma belong in the differential. Interestingly, the consultants all suggest a biopsy of the lesion prior to other testing, and because this tumor is so accessible, a biopsy should not interfere with further testing or treatment. Drs. Weymuller and Marks would then proceed with a CT scan; Dr. Ridge favors an MRI scan. While a chest-ray is in order to rule out metastases, Dr. Weymuller also suggests immunocytochemistry. All the experts agree that the primary tumor should be excised. Dr. Weymuller would perform a total parotidectomy with facial nerve preservation, while Drs. Marks and Ridge suggest a superficial parotidectomy with facial nerve preservation. Drs. Weymuller and Ridge would also perform a modified radical neck dissection. In the absence of cervical disease, Dr. Marks would treat the neck primarily with radiotherapy. Only Dr. Weymuller favors immediate reconstruction and would use a lower trapezius island flap or a large rotational flap. Drs. Marks and Ridge prefer primary closure or skin graft. Drs. Weymuller and Ridge would treat this patient with combined therapy, giving radiotherapy to the primary area and the neck postoperatively at a dose of 55-60 Gy. However, Dr. Marks would treat the primary site postoperatively and the neck primarily with radiotherapy. He would treat the primary site with 59.40 Gy and the neck with 50.40 Gy.(ABSTRACT TRUNCATED AT 250 WORDS)
