Plantar fibromatosis is a noncancerous (benign) growth of connective tissue in the sole (the plantar fascia).

In plantar fibromatosis, bumps develop on the sole and are most obvious when the foot is bent upward against the leg. Most people also have bumps in the palms, usually located at the fourth knuckle.

Treatment is usually not worthwhile unless the bumps become large enough to cause pain when bearing weight. If so, devices that change the position or range of movement of the foot and relieve pressure on affected joints (orthoses) can help redistribute pressure away from the bumps.
