Musculoskeletal system and connective tissue (M00-M99).
- Callus formation (radiographically visualizable scar tissue of bone) after fracture (broken bone).
- Paget’s disease – disease of the skeletal system with bone remodeling.
- Osteomyelitis (bone marrow inflammation)
Neoplasms – tumor diseases (C00-D48)
- Atheromas (popularly known as gruel pouches, bellows tumors, or semolina nodules) – benign neoplasm arising as a result of obstruction of the excretory duct for the sebaceous gland secretion; atheromas present as a pinhead- to chicken-head-sized, rarely apple-sized, benign (benign) cyst in the subcutaneous cell tissue.
- Fibromblastoma – benign neoplasm consisting of fibroblasts (cells of mesenchymal origin occurring in connective tissue).
- Fibrosarcoma – malignant neoplasm arising from connective tissue cells.
- Granulomas – inflammation-related, nodular tissue neoplasm arising from epithelioid cells.
- Hemangiomas (vascular tumors).
- Lipomas (fat tumor)
- Giant cell tumors
- Tendon sheath hygromas – benign growths in the area of a superficial tendon sheath.
- Synovialomas – neoplasm originating from the synovium (synovial fluid) of joints or tendon sheaths.
- Xanthomas – benign neoplasm consisting of fibroblasts, reticulin fibers (lattice fibers) and histiocytes (localized form of a macrophage/fress cell).
