BACKGROUND: There is no agreement as to whether papular acrodermatitis of childhood caused by hepatitis B virus can be differentiated from other papulovesicular acrolocated syndromes. OBJECTIVE: We attempted to establish whether such differentiation is possible comparing histories, signs, and symptoms of all patients who have been previously diagnosed as having papular acrodermatitis of childhood or papulovesicular acrolocated syndromes. METHODS: Files of 308 patients hospitalized in the past three decades were studied. Photographs were examined by a panel of experts to determine whether it was possible to distinguish between papular acrodermatitis of childhood and papulovesicular acrolocated syndromes solely on the basis of cutaneous signs. RESULTS: The retrospective analysis confirmed a significant overlapping of the two types of the disease. The blind survey of photographs of the patients revealed that a distinction between the forms was not clinically possible. CONCLUSION: Acrodermatitis is a self-limiting cutaneous response to different viruses; clinical differences are probably due to individual characteristics of each patient rather than the causative virus.
Acrodermatitis enteropathica (AE) is an autosomic recessive disorder affecting early infancy. Two cases of infantile AE with low plasma zinc levels are reported in which unusually prominent bullous and vesicobullous lesions were seen on the hands and feet, in addition to the more typical erythematous and scaly patches. Both psoriasiform and bullous lesions responded dramatically to oral zinc-sulfate supplementation. The histopathologic features of the bullous lesions of AE have not previously been fully examined. Histologically, the bullous lesions were characterized by intraepidermal vacuolar changes with massive ballooning, leading to intraepidermal vesiculation and blistering, with prominent epidermal necrosis and with no acantholysis. The bullous lesions did not arise on erythematous patchy lesions, but developed ex novo on unaffected skin. The histopathologic differential diagnosis with other bullous conditions is discussed.
