title: Transient bullous dermolysis of the newborn: two additional cases.
abstract: Two cases of transient bullous dermolysis of the newborn are reported. The first patient, a white boy, had normal skin at birth, but multiple blisters soon developed. The oral mucous membranes were not affected. All lesions healed within 4 months without scars but with many milia. At the age of 17 months the boy was reexamined and was found to have no blisters or milia. The second patient, a Japanese baby girl, had extensive denudation of her hands at birth. Generalized blisters and involvement of the oral mucous membrane developed. Blistering stopped within 1 1/4 months, and all lesions healed without scars. Histologically the blisters were subepidermal in both cases. Some lesional basal cells contained periodic acid-Schiff-positive inclusions. Electron microscopy revealed collagenolysis, diminution or loss of anchoring fibrils, and stellate inclusions in dilated rough endoplasmic reticulum in the keratinocytes of the lower epidermis. These stellate inclusions consisted of filamentous bundles with 25 to 33 nm cross-striations.
