Nasal chondromesenchymal hamartoma in an adolescent

Summary 

Nasal chondromesenchymal hamartoma (NCMH) is an extremely rare benign tumour that was first described in 1998. It has been considered to be a disease of infancy. Here we report a case of NCMH in a 12-year-old boy who presented with a tumour in the left nasal cavity. Computed tomography and magnetic-resonance imaging revealed a heterogeneous and polypoid mass. The patient underwent endoscopic surgical excision. Histological analyses of the tumour were consistent with NCMH. This case report indicates that NCMH should be included in the differential diagnosis of paediatric nasal cavity lesions.
