Plantar fibromatosis is a generalized term for a group of conditions that cause benign tumors to grow on the soles of the feet, according to FootVitals. Doctors consider Ledderhose’s disease, juvenile aponeurotic fibroma and aggressive infantile fibromatosis types of plantar fibromatosis.
People with plantar fibromatosis may feel pain and notice lumps on the arches of their feet, explains FootVitals. The location and size of these tumors, called plantar fibroma, influence how much discomfort each patient feels.
Risk factors for developing plantar fibromatosis include a family history of the condition, diabetes mellitus, alcoholism, thyroid problems and liver problems, notes FootVitals. White men over the age of 70 are also more likely to develop this condition. Certain medications and supplements, such as Phenytoin, beta-blocker supplements and high dosages of vitamin C, increase the chance of developing plantar fibromatosis.
Treatment options depend on the discomfort caused by the fibromas, states FootVitals. When the tumors are small, patients may use foot orthotics, padding, arch supports and other methods to reduce pressure on the firbromas. Patients can also apply Verapamil 15-percent gel to their feet, which may shrink the fibromas.
Doctors sometimes treat painful fibromas with cortisone injections, but there is a risk that the injection could cause the tumor to grow or spread, according to FootVitals. Surgical removal is also an option, but fibromas can reoccur after removal.
