Abstract

Fibrodysplasia Ossificans Progressiva(FOP) is a rare autosomal dominant disease, characterized by multiple bony swellings mostly in the axial musculature at shoulder. Diagnosis is based on findings of extra-skeletal ossification in the connective tissues and congenitally malformed big toe. Although the congenitally malformed big toe is present since birth, still its diagnosis is often missed. We report three cases of Fibrodysplasia Ossificans Progressiva. The patients were diagnosed one at 6 years of age, other at 10 years and other at 25 years of age. They had classical features of the disease, congenital hallux valgus deformity of foot and extra skeletal ossification. The objective of reporting these cases is to attract the researcher to do something for its prevention and treatment.
