There are three distinct types of<unk> , each with their own symptoms. They are distinguished by the depth and the size of abnormal lymph vessels, but all involve a malformation of the lymphic system.<unk>  circumscriptum can be found on the skin's surface, and the other two types of<unk> s occur deeper under the skin. *<unk>  circumscriptum, a microcystic lymphatic malformation, resembles clusters of small blisters ranging in color from pink to dark red. They are benign and do not require medical treatment, although some patients may choose to have them surgically removed for cosmetic reasons. * Cavernous<unk> s are generally present at birth, but may appear later in the child's life. These bulging masses occur deep under the skin, typically on the neck, tongue and lips, and vary widely in size, ranging from as small as a centimeter in diameter to several centimeters wide. In some cases, they may affect an entire extremity such as a hand or foot. Although they are usually painless, the patient may feel mild pain when pressure is exerted on the area. They come in the colors white, pink, red, blue, purple, and black; and the pain lessens the lighter the color of the bump. * Cystic hygroma shares many commonalities with cavernous<unk> s, and some doctors consider them to be too similar to merit separate categories. However, cystic<unk> s usually have a softer consistency than cavernous<unk> s, and this term is typically the one that is applied to<unk> s that develop in fetuses. They usually appear on the neck (75%), arm pit or groin areas. They often look like swollen bulges underneath the skin.
