Patient's question:
What is the reason for black spots on the genitalia?Doctor's answer:
A nevus, also known as a melanocytic nevus or a melanoma, is a benign disease characterized by changes in the color of the skin or mucosa due to the proliferation of nevus cells and the production of pigment. Pigmented nevi can remain stable for a long time, and they do not recur after surgical removal; however, it is important to be vigilant as a very small number of pigmented nevi may undergo malignant transformation. They can cause malignant melanoma, which is a type of malignant tumor. It is recommended to undergo surgical resection and treatment as early as possible.
