These are benign bone tumours that form in the bone beneath the toenail. Osteochrondromas account for about half of all benign bone tumours, and occur mostly in children and young adults.

Unless they cause irritation to the surrounding tissue, they are generally not painful. While the exact cause of osteochondroma is not known, there is a genetic link, indicating that there is a form of the disorder that is inherited. However, there’s also a noninherited form of the disorder.

Although individuals may experience symptoms differently, typical symptoms of osteochondromas include:

  • A hard, immobile, detectable mass that is painless
  • Lower-than-normal-height for age
  • Soreness of adjacent muscles
  • Pressure or irritation with exercise

You should note that symptoms of osteochondroma may resemble other medical conditions or problems, so you should always consult your doctor for a diagnosis.

Treatment for osteochondromas varies significantly depending on the size of the overgrowth and the symptoms of the individual. Treatment may include:  

  • Surgery to remove the mass
  • Medications to control pain

If there is no sign of bone weakening or increased overgrowth, observation only may be suggested. Careful follow-up with a doctor to monitor bone growth may be recommended
