Seborrheic warts in darker-skinned individuals appear as raised, brown or black lesions with a rough, crusty texture, often found on the face, neck, or torso. These benign growths are typically associated with aging, genetics, or sun exposure and may be more noticeable against darker skin tones. Treatment options include cryotherapy, laser therapy, or surgical excision to remove the warts, with most cases requiring no treatment unless they cause discomfort or cosmetic concerns.
