Pityriasis Lichenoides et Varioliformis Acuta (Mucha-Habermann). Presented by Henry H. Roenigk, Jr., MD.
This 15-year-old boy first came to the Cleveland Clinic in 1967 with a four-year history of small red asymptomatic nodules which rapidly ulcerated and scarred. He would be free of lesions for about three weeks at a time. Mostly the ventral surfaces of the body were involved with sparing of the face and neck. There were no systemic symptoms.Multiple 0.5- to 1.0-cm sized lesions in various stages, hemorrhagic papules, ulcerations, and scars, primarily involved the trunk. Findings from general physical examination were within normal limits. Results of laboratory studies, including automated multiple analysis system and multiple complete blood cell counts, were all normal.Skin biopsy (Fig 1) shows mild, loose hyperkeratosis, patchy parakeratosis, and irregular acanthosis with elongated blunted rete ridges.
