What causes black spots on lips?

Condition analysis:

The appearance of dark spots on the lips is mainly caused by abnormal melanin deposition. The most common two diseases of abnormal melanin deposition are: mucosal dark spots, It refers to abnormal melanin deposition that is not related to racial pigmentation or pigmentation caused by systemic disease syndrome. Another disease is pigmented intestinal polyposis syndrome.

Mucosal dark spots generally have no symptoms, and are most common on the lower lip. The dark spots are not higher than the mucosal surface, have clear boundaries around them, and are often uniform flakes or small masses. The general diameter is about 5mm. The color of dark spots varies depending on race, individual, the amount of melanin, and where the melanin is located. The lighter the melanin is from the epidermis in the epithelium, the darker the color. This kind of black spots are currently considered to be benign lesions and do not require treatment. However, attention should be paid to observation. If there are changes in color, size, etc., or even symptoms such as ulcers and bleeding, they should be surgically removed to avoid malignant transformation.

Pigmented intestinal polyposis syndrome is an autosomal hereditary disease with familial inheritance. In addition to the vermilion of the lips, pigmentation occurs on the perioral skin, buccal mucosa, palms, soles, and fingers. Pigmentation can occur on the toes, eyelids, nose, etc. It can usually be seen a few months after birth and becomes more and more obvious with age. In addition to pigmentation, the disease also has multiple intestinal polyps. Some patients may also experience symptoms such as periodic abdominal pain, diarrhea, and blood in the stool. In severe cases, complications such as intestinal obstruction and intussusception may even occur. Pigmentation that appears on the skin generally does not cause malignant transformation, but it affects the appearance. There is currently no effective treatment. Intestinal polyps should be treated aggressively to avoid serious complications or even malignant transformation.
