Sucking blister. The oval blister pictured here was present at birth and is a result of normal sucking behavior in utero. Sucking blisters are fairly common and are usually located on the forearm, wrist, or hand. They are most often solitary and involve only one upper extremity. However, lesions involving both hands, or even involving a foot, are sometimes seen. The sucking blister resolves spontaneously as soon as bottle or breast is offered as a dietary substitute.
Vascular malformations. These are congenital malformations that consist of capillary, venous, arterial, or lymphatic abnormalities. There are often combined alformations that comprise different types of vessels. Examples of vascular malformations include port-wine stains (capillary malformation), cystic hygroma (lymphatic malformation), and venous malformations. Vascular malformations are present at birth and grow proportionately with the child. Some vascular malformations may not manifest themselves until adolescence or adulthood. These figures represent venous malformations on the hand and foot.
Vitiligo. These are more illustrations of fairly extensive cases of vitiligo. The condition tends to progress and may even become universal. A variety of treatment modalities are commonly employed, with varying degrees of success. The patient and family should be made aware of the sophisticated cover-up cosmetics that are now available. The use of broad-spectrum sunscreen lotions during the summer months minimizes the con- trast between normal and involved skin. For some patients, the application of topical corticosteroids alone or with brief natural sunlight exposure early in the course of the disease may induce repigmentation. Narrowband UUB is also an effective treatment. Varying combinations of topical or oral psoralens and ultraviolet A light (PUVA) are used in the treatment of vitiligo.
Strawberry hemangiomas (also called strawberry mark, nevus vascularis, capillary hemangioma, hemangioma simplex) may appear anywhere on the body, but are most common on the face, scalp, back, or chest.
