Soft Tissue Masses



A soft tissue mass in the foot is usually a benign thickening of the plantar fascia called a fibroma, or a fluid filled pocket from a joint or a tendon called a ganglion.

Fibromas are found on the bottom of the foot, usually in the arch. They are firm to the touch and can enlarge rapidly.

A ganglion can appear in the foot over any joint or tendon and is caused by irritation of the joint or tendon. They are soft or firm to the touch and can increase and decrease in size on a daily basis.

Signs and Symptoms

  • Painful or non-painful “bump” on the top or bottom of the foot.
  • Redness and swelling on or around the “bump”
  • Pain with walking or with shoes


  • Fibromas can be treated with cortisone injections, Non-steroidal anti-inflammatories, padding, custom molded orthotics, high power laser therapy and surgical removal.
  • Ganglion cysts can treated by draining the fluid, cortisone injections, padding, custom molded orthotics, and surgical removal.
