Osteochondromatosis
A condition that is characterized by multiple benign tumors of cartilage, called osteochondromas, projecting from bone, most often from near the ends of long bones. In a small proportion of cases, an osteochondroma may become malignant. Also known as multiple exostoses. The condition can be hereditary, in which case it is called hereditary multiple exostoses (HMS).

- Osteoclast
A cell that nibbles at and breaks down bone and is responsible for bone resorption. Osteoclasts are large multinucleate cells (cells with more than one nucleus) that differentiate from another type of cell called a macrophage. In normal bone, bone formation and bone resorption are closely coupled processes involved in the normal remodeling of bone. […]
