Fibrodysplasia Ossificans Progressive (FOP) (also known as Myositis ossificans progressiva/Stone man disease/Munchmeyer’s disease) is one of the unfamiliar congenital disorders affecting the musculoskeletal system. It is characterised by extraosseous progressive heterotrophic osteogenesis in muscle, tendon, and ligament and associated deformities in toes. It starts around the age of 3-5 years and aggressively involves the musculoskeletal system; the affected child becomes immobile in the early twenties. The early phase of the disease is often misdiagnosed by medical experts due to its rarity and unfamiliarity. This was a case of FOP in a 5-year-old female child from western Uttar Pradesh. The presenting complaints were swelling in the lower back region, which was gradually increasing in size, and bilateral foot deformity. The diagnosis of FOP was based on elaborated history, clinical examination, and radiological investigation of the skeletal malformations. The child was provided with symptomatic treatment and her parents were counselled regarding the disease course.
