Nasal Chondromesenchymal Hamartoma: A Rare Benign Lesion in Adult Female

Abstract

Nasal chondromesenchymal hamartoma (NCMH) is a rare benign lesion of the sinonasal tract in children and adolescent with orbital involvement. NCMH is histologically composed of nodules of cartilage with cellular density variation and maturation of the chondrocytes, a myxoid to spindle cell stroma, focal osteoclast-like giant cells in the stroma, and erythrocyte-filled spaces. This lesion may present with a destructive pattern on imaging, highly suggestive of malignancy. Total endoscopic resection is the choice of treatment nowadays, however incomplete excision could result in tumor recurrence but rare.
