It results from the entrapment of melanocytes in the dermis during their migration from the neural crest to the epidermis during embryonic development.Among those who are not aware of the background of the Mongolian spots, it may sometimes be mistaken for a bruise indicative of child abuse. Vascular types
Stork bite
Colloquially called a "stork bite", "angels kiss" or "salmon patch", telangiectatic nevus appears as a pink or tanned, flat, irregularly shaped mark on the knee, back of the neck, and/or the forehead, eyelids and, sometimes, the top lip. The skin is not thickened and feels no different from anywhere else on the body; the only difference is in appearance. Nearly half of all babies have such a birthmark. Strawberry mark
An infantile hemangioma, colloquially called a strawberry mark, is a benign self-involuting tumor (swelling or growth) of endothelial cells, the cells that line blood vessels. It usually appears during the first weeks of life and resolves by age 10. It is the most common tumor of infancy.PHACES Syndrome, a rare condition that often involves brain, heart, and arterial abnormalities, is generally accompanied by the presence of large facial hemangiomas. In such cases, what appears to be a small bruise or birthmark may grow rapidly and take on a puffy appearance in the first days or weeks of life. Port-wine stain
Port-wine stains, also known as nevus flammeus and sometimes mistaken for strawberry marks, are present at birth and range from a pale pink in color, to a deep wine-red.
Anticoagulation such as heparin, intravenously (IV) or injectable (shot) can be given while inpatient and followed by heparin. A recent trial in 2015,  the Cervical Artery Dissection in Stroke Study (CADISS), examined the efficacy of antiplatelet and anticoagulation treatment with the primary endpoint of ipsilateral stroke or death in individuals with symptomatic dissections. The CADISS trial revealed no significant difference in efficacy of antiplatelet and anticoagulant drugs in preventing strokes or death, but did note that strokes were rare in either group, and rarer than what has been reported in observational studies. == References ==
