چکیده
Patients with the skin disorder pityriasis lichenoides et varioliformis acuta (PLEVA) develop recurrent, self-healing papulonecrotic lesions that contain infiltrates of cytologically and antigenically normal T lymphocytes. DNA extracted from the lesions of 3 patients with PLEVA was analyzed for rearrangement of beta-T-cell receptor genes for the purpose of assessing the clonality of T lymphocytes within the tissues of this disease. Lesions from all 3 cases showed clonal gene rearrangements. In each of 2 cases from which two separate lesions were biopsied, identical rearrangements were found in specimens from both sites. DNA from a variety of inflammatory lesions obtained from patients with other types of skin diseases failed to show detectable rearrangements of beta-T-cell receptor genes. These results suggest that PLEVA represents a T-cell lymphoproliferative process, rather than an inflammatory disorder, as had been previously thought.

Pityriasis lichenoides is an uncommon, acquired, idiopathic, self-limiting skin disease that poses a challenge to patients and clinicians to diagnose and treat. Several variants exist including pityriasis lichenoides et varioliformis acuta (PLEVA), pityriasis lichenoides chronica (PLC), and febrile ulcer-onecrotic Mucha-Habermann disease. Precise classification can be difficult due to an overla...

This report describes the case of a 76 year old man who suffered from febrile ulceronecrotic Mucha–Habermann disease (FUMHD). Despite this patient’s typical clinical and histological findings, the fulminating course led to death. Polymerase chain reaction (PCR) analysis of the skin lesions showed that the infiltrating cells were monoclonal in origin and were from an aberrant clone. FUMHD is a v...
