osteochondromatosis

Osteochondromatosis, also known as hereditary multiple exostosis, is a skeletal development disorder primarily affecting children. It is characterized by the development of bony protrusions on long bones, ribs, and vertebrae. This condition can arise spontaneously, after trauma, or have a hereditary basis.1

If severe, osteochondromatosis can impede bone growth, leading to dwarfing. It may also cause disabilities by pressing on surrounding tissues like tendons, blood vessels, or nerves. Typically, these growths stop developing at puberty. However, a rare reactivation of growth in adulthood can be an indicator of malignant changes, potentially developing into a chondrosarcoma. Treatment is generally not required unless the growths interfere with function, in which case surgical removal is an option.1
