A plantar fibroma is a pea-sized nodule that is found in the plantar fascia, a stretch of connective tissue from the toes to the heels. Generally a plantar fibroma is found in the arch of the foot. This nodule is not cancerous but may enlarge. It is sometimes found in both feet. Pain may or not occur with a plantar fibroma. If the location of the fibroma is not in an area where there is pressure on the foot from walking, there will be no pain. However, when the fibroma is located in the arch of the foot where there’s pressure from walking, there will be pain with every step. Cause No one knows why plantar fibromas occur. Treatment and Prevention Since the fibroma may increase in size – and the pain increases with it – it’s important to seek medical attention. The more mass that is disrupted by the fibroma, the more complicated the condition can become. Treatment begins with a thorough medical evaluation and imaging techniques to see how much tissue has been affected. Medical treatment may include corticosteroid injections; however, these have been associated with fat pad atrophy, which can cause further problems with the foot, as the foot’s natural cushioning ‘material’ is dissolved. Surgery may not be a solution because it can lead to the development of other foot conditions such as hammertoes, flat feet, bunions, and other issues. Also, plantar fibromas have a high reoccurrence rate when surgery is performed. Supporting the foot with orthotic devices customized to the foot is essential. For an over-the-counter insole consider a sensitive foot insole or cushioned insoles.
