title: Nasal chondromesenchymal hamartoma in a child.
abstract: Nasal chondromesenchymal hamartoma (NCMH) is a benign tumor that was described in 1998. The occurrence of this lesion in the nasal cavity of infants and children is especially rare, with only 21 cases reported in the international literature. We report a 12-month-old boy with respiratory distress due to nasal obstruction. Computed tomographic scan and magnetic resonance imaging examination demonstrated a soft-tissue mass obstructing the left nasal cavity. Digital subtraction angiography and preoperative superselective embolization with microparticles were also performed. The tumor was completely resected surgically. Histopathology and immunohistochemical analyses of the tumor disclosed a NCMH. The imaging characteristics of the tumor are described and the radiology literature is reviewed.
