Minimal invasive treatment of liver and kidney metastasis in mucosal melanoma of the right inferior turbinate.

This case report describes an 80-year-old female patient who initially presented with nasal epistaxis. The patient had a history of atrial fibrillation and arterial hypertension. Computed tomography of the facial sinuses revealed a large mass in the inferior right turbinate with slight expansion into the maxillary sinus. Endoscopic excision of the right nasal cavity was performed, and the histologic workup revealed mucosal melanoma of the nasal cavity (cT3, cN0, cM0). A medial maxillectomy of the right side, including 2 biopsies within 1 month, showed no signs of recurrence. After 1 year, the patient was diagnosed with liver and renal metastases in a follow-up CT, which were treated with stereotactic radiofrequency ablation. After spending 2 weeks in the intensive care unit due to postoperative complications, the patient recovered and was discharged from the hospital in good condition. A promising alternative minimally invasive therapeutic strategy, highlighted by our case, should be considered as a primary goal of tumor reduction.
