The FP diagnosed a hard corn secondary to the hammer-toe deformity. Corns can be seen on a non-weight-bearing surface, such as the dorsal proximal interphalangeal joints in patients with hammer-toe deformity. It is often referred to as a hard corn in that location. Corns in the interdigital spaces (commonly in the fourth space) are referred to as a soft corns. Corns are often slightly hyperpigmented (or normal in color) and are usually well demarcated. The lesion may have a hard or soft nucleus upon debridement.
Common associated signs include: prominent underlying bony structure, gross deformity of the foot (eg, cavus [high-arch] foot deformity, flatfoot deformity, bunion deformity, or lesser digital deformity), decreased ankle dorsiflexion, and an overall decrease in pedal joint range of motion.
The FP debrided the dead hyperkeratotic skin with a #10 scalpel blade. He then recommended that the patient use a pumice stone on a regular basis to keep the corn from regrowing. He discussed the possibility of surgery to correct the underlying hammertoe deformity. The patient, however, was not ready to undergo surgery but said she would consider it if the corn recurred.
