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.
