Abstract

In 1916, Mucha,1 of Vienna, described a polymorphic eruption of the skin characterized by macular, moderately scaly papular and papulonecrotic lesions which formed hemorrhagic crusts and left small, whitish scars, often with a halo of moderate pigmentation. New lesions appeared in crops, while older lesions involuted in a few weeks. Subjective or objective symptoms, other than the presence of the eruption, were lacking, and, because there was some resemblance histologically to the complex, chronic dermatosis known as pityriasis lichenoides chronica of parapsoriasis guttata, Mucha reported the condition as a variant of this disease. Similar cases were reported in Vienna by Rusch,2 Oppenheim3 and Krüger4 within the next five years, but none were cited from other countries until 1926, when Habermann5 reported two cases in Germany under the title of pityriasis lichenoides et varioliformis acuta. Gray6 reported the first case in England
