Abstract:
Although myopathy or myositis may occur in systemic sclerosis (SSc) as well as soft tissue calcification, ossification is not a feature of the disease. Here we present an unusual case of extended calcification and, to a lesser degree, ossification of the right gluteal region, lateral thigh, and knee, with associated myopathy and functional impairment. Heterotopic ossification (HO), or myositis ossificans, has not been reported so far in scleroderma patients, making this case, in our opinion, unique and interesting. However, differential diagnosis from other causes of extraskeletal ossification, such as tumours or tumour-like conditions, is required.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
