A Case of Melanoma in situ in a Child Presented with Melanonychia / 대한피부과학회지

ABSTRACT

Melanonychia is a darkening of the nails and its importance is that it may indicate the presence of a subungual malignant melanoma. Because the incidence of malignant melanoma is quite small in children, clinicians have had difficulties as to whether or not to perform a nail matrix biopsy in the children with melanonychia. Herein, we report the case of a 6-year-old boy that presented with melanonychia, which was determined to be confirmed melanoma in situ.
