[Clinical heterogeneity of poikilodermatous mycosis fungoides: A retrospective study of 12 cases].

Ann Dermatol Venereol 2020 Jun - Jul;147(6-7):418-428. Epub 2020 Mar 27.

Clinique dermatologique, université de Strasbourg et hôpitaux universitaires de Strasbourg, 1, place de l'Hôpital, 67091 Strasbourg cedex, France.

Introduction: Poikilodermatous mycosis fungoides is a rare and indolent clinical variant of mycosis fungoides (MF). It can be difficult to distinguish from poikilodermatous parapsoriasis, a group of chronical dermatoses that may sometimes progress to MF. We aimed to specify the clinical, histopathological and developmental features of these entities by means of a retrospective study of 12 cases followed in our center. Read More

Multiple Fixed Drug Eruption Mimicking Parapsoriasis en Plaque in a Patient with Hepatitis C Virus Infection.

Case Rep Dermatol 2020 Jan-Apr;12(1):25-32. Epub 2020 Feb 4.

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

Although hepatitis C virus (HCV) infection is often associated with extrahepatic cutaneous manifestations such as lichen planus, it is unclear whether HCV or HCV-specific immune responses play a pathophysiological role in the development of HCV-related cutaneous diseases. We recently treated a patient who developed parapsoriasis en plaque-like lesions after ingestion of various drugs. She showed hypersensitivity to multiple drugs after interferon therapy. 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.

Next-Generation Sequencing Technologies for Early-Stage Cutaneous T-Cell Lymphoma.

Front Med (Lausanne) 2019 13;6:181. Epub 2019 Aug 13.

Department of Dermatology, Kagoshima University Graduate School of Medical and Dental Sciences, Kagoshima, Japan.

The diagnosis of early stage cutaneous T-cell lymphoma is often difficult, particularly in mycosis fungoides (MF), because the clinical presentation, histological findings, and laboratory findings of MF resemble those of inflammatory skin diseases such as atopic dermatitis, psoriasis, and parapsoriasis en plaque. Furthermore, MF sometimes occurs with or after these inflammatory skin diseases. The current diagnostic criteria heavily rely on clinical impressions along with assessments of T cell clonality.

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.
