Have you noticed a recent lump on the bottom of your foot? It could be a fibrous plaque called a plantar fibroma. These fibromas are thickenings of collagen that form on the plantar aponeurosis. The mass may enlarge over a period of months or even years. It can cause pain while walking or standing. The fibromas can form due to injury or an inherited predisposition. Treatment may consist of orthoses, stretching exercises, and topical medications. Keep inspecting your feet!
