Am J Dermatopathol 2021 Mar 30. Epub 2021 Mar 30.

Advanced DermCare, Danbury, CT; Department of Pathology, Phoenix Children's Hospital, Phoenix, AZ; Department of Dermatology, HCA Healthcare/USF Morsani College of Medicine GME, Largo Medical Center, Largo, FL; and Division of Dermatology, Department of Pediatric Dermatology, Phoenix Children's Hospital, Phoenix, AZ.

Abstract: A 15-year-old boy presented to the pediatric dermatology department with long-standing patch stage CD8+ mycosis fungoides and subsequent development of recurrent pityriasis lichenoides et varioliformis acuta eruptions. There have been rare reports of patients with chronic, recalcitrant pityriasis lichenoides developing mycosis fungoides, but we believe this to be the second case of mycosis fungoides preceding a diagnosis of pityriasis lichenoides, and the first case reported in the pediatric population.

A Diagnostically Challenging Case of Febrile Ulceronecrotic Mucha-Habermann Disease in an Adult Female Successfully Treated with Methotrexate and Cyclosporine.

Case Rep Dermatol 2021 Jan-Apr;13(1):12-17. Epub 2021 Jan 21.

Division of Dermatology, Department of Internal Medicine, Albert Einstein College of Medicine, Bronx, New York, USA.

Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare and severe variant of pityriasis lichenoides et varioliformis acuta (PLEVA) characterized by intermittent pyrexia, acute onset of generalized ulceronecrotic lesions, and histopathology suggestive of PLEVA. Prompt diagnosis and treatment are necessary to halt the progression of this potentially fatal disease; however, the widely variable presentation of FUMHD in addition to its rarity poses a diagnostic challenge. We report the case of a previously healthy 43-year-old woman who presented to the emergency department with 1 month of generalized rash and intermittent fevers. Read More

Dermoscopic characterization of guttate psoriasis, pityriasis rosea, and pityriasis lichenoides chronica in dark skin phototypes: An observational study.

Dermatol Ther 2021 Jan 13;34(1):e14631. Epub 2020 Dec 13.

Department of Dermatology, Venereology and Leprosy, Himalayan Institute of Medical Sciences, Swami Rama Himalayan University, Dehradun, India.

Dermoscopy as a diagnostic tool is attaining impetus in inflammatory dermatoses with the cumulative description of characteristic findings in most dermatoses obviating at times the need of biopsy. In this retrospective observational study, 20 histopathology confirmed cases each of pityriasis rosea (PR), guttate psoriasis (GP), and pityriasis lichenoides chronica (PLC) seen over a period of 3 years were included. Dermoscopy images were extracted from photography archives for evaluation and three lesions from each patient (60 lesions each) were analyzed. Read More

Pityriasis lichenoides et varioliformis acuta (PLEVA) is a rare cutaneous eruption of erythematous macules and papules distributed over the flexural surfaces and the trunk. Histopathologic analysis is useful in diagnosis, and dermoscopic findings have been described in several small case series. We present a case of a mid-20s female who was diagnosed with PLEVA based on clinical and histopathological findings, and we also demonstrate a unique dermoscopic finding. Read More

Pityriasis lichenoides acuta (PLEVA) pemphigoides: A rare bullous variant of PLEVA.

Pediatr Dermatol 2020 Jul 30;37(4):710-712. Epub 2020 Apr 30.

Division of Paediatric Dermatology, Children's Hospital AUF DER BULT, Hannover, Germany.

Although the clinical presentations of patients with pityriasis lichenoides et varioliformis acuta (PLEVA) may vary, bullae are not usually part of the clinical spectrum. To date, only two other cases of a bullous variant of PLEVA with evidence of autoantibodies against hemidesmosomal antigens have been reported. The term PLEVA pemphigoides was suggested for this unique clinical, pathological and serological combination of both PLEVA and bullous pemphigoid. Read More

Pityriasis Lichenoides: A Large Histopathological Case Series With a Focus on Adnexotropism.

Am J Dermatopathol 2020 Jan;42(1):1-10

Department of Dermatology, Hôpital Necker-Enfants Malades, Paris, France.

Introduction: Pityriasis lichenoides (PL) is an infrequent skin disorder. The clinical manifestations are usually specific enough for a reliable diagnosis, although the histopathological assessment of a biopsy is sometimes needed to differentiate between PL and a range of other diseases. The objectives of this study were to review cases of PL managed in our hospital, confirm the classical histopathological features of PL, and identify signs that may be of value in the diagnosis of PL.
