fibrodysplasia ossificans progressiva (FOP)

A rare genetic disease characterized by acute soft-tissue swelling after minor trauma, such as dental work or intramuscular injections, that leads to heterotopic bone formation.

fi·bro·dys·pla·si·a os·sif·'i·cans pro·gres·si·'va

[MIM*135100]

a generalized disorder of connective tissue in which there is ectopic ossification with bone replacing tendons, fasciae, and ligaments; a lethal genetic disorder of autosomal dominant inheritance.

Farlex Partner Medical Dictionary © Farlex 2012

A rare idiopathic or autosomal dominant MIM 135100 condition of irregular penetration and pre-pubertal onset, in which connective/interstitial tissues undergo extensive fibrosis and heterotopic ossification of ligaments, tendons, muscle, fascia, aponeuroses and skin, first seen in late childhood as firm masses. The abnormal development of bone may lead to stiffness in affected areas and may also limit movement in affected joints, e.g., knees, wrists, shoulders, spine, and/or neck
