The blackest child in the world is Nigerian boy Kwasi Nyantakyi, who was found in 2009 to have a rare genetic mutation that caused his skin to be particularly dark. This genetic variant, known as congenital melanocytic nevus, causes dark patches on the skin, eyes and hair.
According to reports, Kara Chiklu was born with not particularly dark skin, but his skin gradually became darker over time. By the time he was four years old, he was completely dark, and his parents noticed that his eyesight was deteriorating. Currently, Carla Chiklu lives an ordinary life in his hometown, and although he has faced some difficulties, his family and community have always supported him.
Generalized hyperpigmentation is a rare genetic disorder with an incidence of about 1 in 200,000 people. The disease usually does not affect the patient's health, but it may have some impact on the patient's psychological and social life. Therefore, there is a need for more understanding and support for patients and their families.
