Synopsis

Pincer nail is characterized by transverse over-curvature of the nail plate that increases along the longitudinal axis of the nail and progressively pinches the nail bed distally. The curvature commonly increases from proximal to distal, giving rise to a triangular shape when seen from above.

The condition occurs frequently on the toes but only rarely on the fingers. Pain is a common complaint and can be intense. In time, the lateral nail plate edges dig into the lateral grooves and progressively pinch the nail bed. Ultimately, the lateral borders of the nail plate join together leading to the so-called trumpet-nail.

Pincer nail deformity is caused by a developmental anomaly that can be inherited or acquired. Acquired cases may be caused by osteoarthritis, ill-fitting shoes, subungual tumors, psoriasis, onychomycosis, arteriovenous fistula of the forearm, Kawasaki disease, and paraneoplastic sign.
