ICD-10-AM Code: M72.3

Brief description

Plantar fibromatosis is a rare hyperproliferative disease affecting the plantar fascia.  It is similar to dupuytren disease in the hand.  Fibrous nodule and cord formation in the fascia leads to puckering and thickening of the skin on the underside of the foot.  Contractures may form.  It is a separate disease from plantar fasciitis.

Confirming the diagnosis

Diagnosis is usually made on the clinical presentation.  Radiological imaging (ultrasound, X-ray, MRI) can be useful to rule out other causes of symptoms.

The relevant medical specialist is an orthopaedic surgeon or rheumatologist.

Clinical onset

The condition most commonly affects males over 60.  Once the diagnosis has been confirmed, the clinical onset can be back-dated to the time of onset of first symptoms.  

Clinical worsening

The usual course of plantar fibromatosis is for it to progress over time.  Treatment options are mostly symptomatic (orthotics, antiinflammatory drugs).  Surgery is generally ineffective.  Worsening beyond the normal course of the condition will be difficult to establish.
