D10-D36: Benign neoplasms

D16: Benign neoplasm of bone and articular cartilage

Benign neoplasms of bone and articular cartilage are non-cancerous growths that occur within the bones or the connective tissue that cushions the joints. These growths can develop anywhere in the body but are more common in the long bones of the arms and legs and the vertebral column. Despite being benign, these neoplasms may cause pain, swelling, and limited movement if they press on nearby nerves or disrupt the function of the joint. The exact cause of these neoplasms is unclear, but they may occur due to abnormal tissue growth or as the result of injury or disease. Over time, these neoplasms may grow larger but they rarely spread to other parts of the body. Most people with benign neoplasms of bone and articular cartilage have a good prognosis although the condition may return or coexist with other bone conditions.
