Primary sinonasal mucosal melanoma (SNMM) is a rare malignancy. The mainstay treatment of primary SNMM is surgical excision with or without adjuvant radiotherapy. However, clear margin is sometimes difficult to achieve due to considerable destruction of surrounding structures. The utilization of computer-assisted navigation system (CANS) ensures safety during surgery. A 63-year-old female came to our hospital due to progressive right orbital fullness and diplopia for 2 weeks. Magnetic resonance imaging with gadolinium enhancement documented a right sinonasal tumor invading the right ethmoid sinus, right maxillary sinus, and right conal space. Transnasal endoscopic tumor excision was performed with the aid of CANS. Histopathological and immunophenotypic analysis showed primary SNMM. The patient received subsequent dacarbazine chemoradiotherapy. Follow-up sinoscopic examination six months after surgery showed good wound healing and disease status.
