👉 Telonemia is a type of pigmented skin condition characterized by patches of dark, brown or black pigmentation on the body that can appear anywhere, including on the face, arms, legs, and even the back of the neck. These patches are often associated with pigmentation disorders such as vitiligo, which is a genetic disorder caused by a deficiency in melanin production. Telonemia can also be influenced by environmental factors such as exposure to sunlight or certain medications.
