It primarily affects children < 14 years old. DPM is characterized by rapid sclerosis with circumferential involvement that frequently extends to the fascia, muscle and bone. Disease progression often involves the development of sclerotic plaques, chronic skin ulcers and painful joint contractures, leading to patient immobility and a high mortality rate.
