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

Pediatr Dermatol 2020 Apr 30. 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.

Department of Medical Oncology, The Canberra Hospital, Garran, Australian Capital Territory, Australia.

Checkpoint inhibition is the mainstay of treatment in metastatic melanoma. More recently combined cytotoxic T-lymphocyte antigen-4 and programmed-death-1 blockade has resulted in improved response rates and overall survival in treatment naïve patients compared to monotherapy albeit with increased rates of adverse events. Dermatologic toxicities are an emerging consequence of the use of checkpoint inhibitors and have reportedly been more prevalent with the use of combined therapy. Read More

Department of Pathology, School of Medicine, Gaziosmanpasa University, Tokat, Turkey.

Pityriasis lichenoides (PL) is a spectrum of inflammatory skin diseases which include PL et varioliformis acuta (PLEVA) and PL chronica (PLC) as two ends of the disease and rarely both entities can coexist on the same patient. Treatment options are based on case series-reports, and anecdotes, and include topical corticosteroids, topical immunomodulators, systemic antibiotics (tetracycline, erythromycin), and phototherapy. Herein, we report a 13-year-old boy, exhibiting mixed manifestations of PLEVA and PLC lesions concurrently, with a rapid and dramatic response to azithromycin monotherapy. Read More

Pityriasis lichenoides is a rare inflammatory dermatosis occurring in young subjects. It evolves into rashes on the trunk and the limbs which regress spontaneously. We here report a particular case of pityriasis lichenoides whose diagnosis was adjusted due to the scar appearance of the lesions. Read More

Pityriasis Lichenoides, Atypical Pityriasis Lichenoides, and Related Conditions: A Study of 66 Cases.

Am J Surg Pathol 2018 08;42(8):1101-1112

Research Unit Dermatopathology, Department of Dermatology, Medical University of Graz, Graz, Austria.

Pityriasis lichenoides (PLs) is an uncommon skin disease of unknown etiology. In recent years, an atypical form of PL has been described, showing overlapping features with mycosis fungoides (MF) and lymphomatoid papulosis. We studied 66 patients with an initial histopathologic diagnosis of PL (M:F=34:32; median age, 25 y; range, 7 to 85 y). Read More

Varicella zoster virus as a possible trigger for the development of pityriasis lichenoides et varioliformis acuta: retrospective analysis of our institutional cases.

Clin Exp Dermatol 2018 Aug 23;43(6):703-707. Epub 2018 May 23.

Department of Dermatology, Kyorin University School of Medicine, Tokyo, Japan.

Although numerous infective agents, including varicella zoster virus (VZV), have been described in association with pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC), none has been identified consistently in these lesions. We sought to immunohistochemically identify VZV glycoprotein (g)E antigens in the vascular endothelium in PLEVA and PLC lesions, based on our previous observation that gE was detected in the vascular endothelium and eccrine unit up until 2 months and 2.5, respectively, years after herpes zoster (HZ) infection.

Pityriasis lichenoides-like drug reaction: A clinical histopathologic study of 10 cases.

Dermatol Online J 2017 Nov 15;23(11). Epub 2017 Nov 15.

Department of Pathology and Laboratory Medicine, Weill Cornell Medicine, New York, New York.

Background: Lymphomatoid drug reactions can mimic endogenous T and B cell lymphoproliferative diseases.

Objectives: We present a novel form of cutaneous drug reaction with features of pityriasis lichenoides (PL), a recognized form of T cell dyscrasia.

Methods: Ten cases were studied where a cutaneous eruption exhibiting semblance to PL within a few weeks to months after starting a particular drug. Read More

Autoinflammatory keratinization diseases: An emerging concept encompassing various inflammatory keratinization disorders of the skin.

J Dermatol Sci 2018 May 1;90(2):105-111. Epub 2018 Feb 1.

Department of Dermatology, Fujita Health University School of Medicine, Toyoake, Japan.

Classifying inflammatory skin diseases is challenging, especially for the expanding group of disorders triggered by genetic factors resulting in hyperactivated innate immunity that result in overlapping patterns of dermal and epidermal inflammation with hyperkeratosis. For such conditions, the umbrella term "autoinflammatory keratinization diseases" (AIKD) has been proposed. AIKD encompasses diseases with mixed pathomechanisms of autoinflammation and autoimmunity, and includes IL-36 receptor antagonist (IL-36Ra)-related pustulosis, CARD14-mediated pustular psoriasis, pityriasis rubra pilaris (PRP) type V, and familial keratosis lichenoides chronica (KLC).

Pityriasis Rosea: Diagnosis and Treatment.

Am Fam Physician 2018 Jan;97(1):38-44

Emory University School of Medicine, Atlanta, GA, USA.

Pityriasis rosea is a common self-limiting rash that usually starts with a herald patch on the trunk and progresses along the Langer lines to a generalized rash over the trunk and limbs. The diagnosis is based on clinical and physical examination findings. The herald patch is an erythematous lesion with an elevated border and depressed center. Read More

Possible role of plasmacytoid dendritic cells in pityriasis lichenoides.

Clin Exp Dermatol 2018 Jun 19;43(4):404-409. Epub 2018 Jan 19.

Department of Dermatology, American University of Beirut Medical Center, Beirut, Lebanon.

Background: Plasmacytoid dendritic cells (pDCs) and their product, type I interferons (IFNs), have been implicated in the pathogenesis of several skin disorders characterized by an interface dermatitis (ID) pattern, such as lichen planus (LP). A type I IFN signature has previously been documented in pityriasis lichenoides (PL). Although pDCs are known to be the main source and most potent producers of local type I IFNs, their role in PL has not been investigated. Read More

Pityriasis lichenoides: Long-term follow-up study.

Pediatr Dermatol 2018 Mar 9;35(2):213-219. Epub 2018 Jan 9.

Department of Dermatology, School of Medicine, Johns Hopkins University, Baltimore, MD, USA.

Background/objectives: Pityriasis lichenoides is an uncommon papulosquamous disorder of unknown etiology. The objective of this study was to review the clinical features and treatment responses of individuals with pityriasis lichenoides seen at a tertiary referral center.

Methods: Seventy-five patients diagnosed with pityriasis lichenoides between 1997 and 2013 were reviewed, and 46 had long-term follow-up via telephone interviews. Read More
