Pityriasis Rosea (Herald Spot)
A 25-year-old Black female required dermatological advice because of a solitary lesion which had appeared over the right side of her neck 2 weeks earlier. Clinically, there was an oval, erythematous, somewhat hyperkeratotic and brilliant asymptomatic patch (Fig. 1). It was followed, about 3 weeks later, by a generalized rash of the trunk and extremities, composed of smaller furfuraceous spots. Histopathologically, the larger patch over the neck showed mild degree of hyperkeratosis, spongiosis and acanthosis. Dilatation of the superficial dermal vessels, a perivascular infiltrate including mainly lymphocytes and a few plasma cells, and some exocytosis were also noticed (Figs. 2 and 3). Address: Leopoldo F. Montes and Ricardo Cebaltos Laboratory of Dermatopathology Department of Dermatology University of Alabama in Birmingham Medical Center Birmingham, Alabama 35294 U.S.A.
