Due to its rarity, lack of specific imaging features, and significant histological overlap with other tumors, the diagnosis poses a challenge for clinicians, radiologists, and pathologists. We present a case of a 68-year-old male with progressively worsening nasal obstruction over 6 months, ultimately diagnosed with nasal myoepithelioma. Approximately 3 months after endoscopic transnasal tumor resection, the patient showed no signs of recurrence. Low cytological atypia, a low Ki-67 proliferation index, and characteristic immunohistochemical findings support the diagnosis of benign myoepithelioma. This case suggests that myoepithelioma should be considered in the differential diagnosis when benign-appearing tumors are observed in the nasal cavity or paranasal sinuses. A multidisciplinary approach integrating imaging, histopathology, and immunohistochemistry is essential for establishing an accurate diagnosis.<\/jats:p>","DOI":"10.25259\/cytojournal_134_2025","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T05:15:22Z","timestamp":1786511722000},"page":"51","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Myoepithelioma
