We report the case of a four-year-old female child with a one-year history 14 of nasal obstruction and facial swelling. A large enhanced lesion with amorphous 15 densities spreading into the right cribriform plate and floor of sphenoid sinus, 16 laterally into the right lamina papyracea, inferolaterally into the medial wall of 17 maxillary sinus, posteriorly into the nasopharynx and superior aspect of oropharynx 18 was observed on CT scan. The mass was excised by Caldwell Luc’s endoscopic 19 medial maxillectomy via sublabial approach. CMF was confirmed 20 histopathologically. 21 Keywords: Chondromyxoid fibroma, benign neoplasm, lamina paprycea. 22 23 Introduction 24 Chondromyxoid fibroma (CMF) is a rare benign tumour, estimated to represent less 25 than 1% of all primary bone neoplasm and characterised by incomplete 26 differentiation with chondroid, myxoid and fibrous areas in varying proportions.[1] 27 CMF usually involves metaphysis of long tubular bones mainly proximal tibia and 28 Provisionally Accepted for Publication
