Cartilage Analogue of Fibromatosis in the Maxillary Alveolar Bone

Cartilage analogue of fibromatosis is a relatively common tumor in the palms and soles of young children and adolescence. The characteristic histological finding of the tumor is the differentiation toward cartilage formation within a background of fibromatosis-like growth. Therefore, the tumor may cause potential diagnostic problems in the maxillofacial bones where it has not been described. The purpose of the present report is to describe the imaging characteristics, histological and immunohistochemical features of an extremely rare case of cartilage analogue of fibromatosis in the maxillary alveolar bone of a 25-year-old female.
