Melanonychia Striata: A Case Report

Abstract

Subungual melanoma has higher mortality than other skin melanomas caused by late initial diagnosis of this disease, leading to a poor prognosis. Two-thirds of subungual melanoma symptoms begin with melanonychia striata, appearing as brown or black-pigmented lines of the nail plate. In this case report, we presented a case of melanonychia striata in a 30-year-old male. Longitudinal excision or partial avulsion was performed, followed by histopathology examination to exclude malignancy and determine further management for this case.
