Hard Corn (Intractable Plantar Keratosis(IPK), Benign Nucleated Neoplasm of Skin)

Updated: Sep 29, 2019

Cause: Pressure, friction, hereditary

Appearance: Hard corn or “seed like” collection of cells on the bottom of the foot with a center nucleus or “core”. Typically appear in the forefoot or toes

Treatment: Debridement and removal of core, offloading with pads or silicone, orthotics, daily use of urea cream. Surgery can be attempted if there are structural abnormalities in the foot/leg.

Long-term prognosis: IPK’s are notoriously stubborn despite routine excision, surgery and offloading treatments. Often athletes will opt for periodic debridement by their podiatrist instead of attempting surgery with no guarantee of success. Typically, periodic debridement alleviates pain and allows for full activity.

Who to call: Podiatrist
