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.
Systemic lupus erythematosus. Image illustrates cutaneous involvement of systemic lupus erythematosus (SLE) in the classic butterfly pattern on the face. This macular and intensely erythematous eruption is frequently aggravated by sun exposure and may flare with other symptoms of systemic disease.
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.
Verruca vulgaris. The common wart is a benign growth caused by localized infection with one of the many types of human papillomavirus. These small DNA viruses are part of the papovavirus group. Warts are especially common among children and adolescents and may occur on any mucocutaneous surface. The hands are a particularly frequent location. The typical wart is a roughsurfaced nodule that may be either lighter or darker than the surrounding skin.
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.
