CHONDROMYXOID FIBROMA OF PARANASAL SINUSES - REPORT OF 2 CASES PRESENTING WITH NASAL OBSTRUCTION

Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor that often occurs in the metaphyses of long bones. Tumors of the craniofac ial bones are extremely rare and most often involve the mandible and t he maxilla. This report presents the clinicopathological and radiologi cal features of two unusual cases of CMF arising in the paranasal sinu ses that presented with nasal obstruction. The tumors arose in the sph enoid and ethmoid sinuses and were treated by curettage and resection, respectively. One of the two patients was 20 days old, suggesting a p ossible congenital origin.
