👉 Neohelicoma is a type of skin cancer that occurs when melanin production in the epidermis (the outermost layer of the skin) fails to properly develop and maintain its pigment. This causes the skin cells to turn yellow or brown, often known as "neohelicity," due to the lack of pigment in the skin's top layers. Common symptoms include scaling, redness, itching, and a feeling of warmth or burning on the affected area.
