[Progressive myositis ossificans. Stone man]

Area of Science:

• Connective tissue disorders
• Genetic diseases
• Musculoskeletal conditions

Background:

• Myositis ossificans progressiva (MOP) is a rare autosomal dominant hereditary connective tissue disease.
• Characterized by progressive ossification of muscles and connective tissues, leading to immobilization.
• Typically presents in childhood with variable clinical expression.

Observation:

• A case of a 29-year-old woman with classic MOP features is presented.
• The patient exhibited typical signs and symptoms of the disease.
• This presentation underscores the diagnostic criteria for MOP.

Findings:

• MOP involves progressive ossification impacting the spinal cord and proximal extremities.
• Leads to significant functional limitations, including immobilization and articular dysfunction.
• Variable expression is a key characteristic, despite complete genetic penetrance.

Implications:

• Understanding MOP pathogenesis is crucial for developing targeted therapies.
• Early diagnosis and management can potentially mitigate disease progression.
• Further research into treatment options is warranted for this rare condition.
