Pitfall in pigmentation: pseudopods in the nail plate

Norbert Haas et al. Dermatol Surg. 2002 Oct.

Abstract

Background: We present here a patient with an unusual type of nail plate pigmentation featuring pseudopod formation.

Objective: To identify additional dermoscopic criteria.

Methods: Dermoscopy of the nail with control biopsy.

Results: Pseudopods of the nail resulted from erythrocytes entrapped between the layers of the nail plate.

Conclusion: Pseudopod formation of the nail may represent a diagnostic criterion to distinguish hemorrhage and melanoma of the nail apparatus.
