Zhonghua Yi Xue Za Zhi 2021 Jun;101(20):1458-1462

Department of Dermatology, the First Affiliated Hospital of Nanjing Medical University, Nanjing 210029, China.

Since the discovery of Epstein-Barr (EB) virus from the cultured cells in Burkitt lymphoma tissue in African children in 1964, we have gradually taken in its oncogenicity and the link between this virus and multiple mucocutaneous diseases. This review exhibits the process of EB virus infection and summarizes the clinical manifestations and varied prognosis of EB virus-associated skin diseases. The cases of common skin diseases including psoriasis, dermatomyositis, pemphigus, pemphigoid, parapsoriasis, atopic dermatitis, urticaria, systemic lupus erythematosus, scleroderma, panniculitis,erythema multiforme and vasculitis coinciding with EB virus infection were collected for the analysis of their EB virus-associated complications, treatments and outcomes.

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

Dermatology, Colentina Clinical Hospital, Bucharest, ROU.

Primary cutaneous CD30-positive lymphoproliferative disorders represent the second most common subgroup of cutaneous T-cell lymphomas and include lymphomatoid papulosis, primary cutaneous anaplastic large cell lymphoma, and borderline lesions. Primary cutaneous anaplastic large cell lymphoma is characterized by the presence of solitary or localized nodules or tumors located on the extremities or the cephalic or cervical region. Large plaque parapsoriasis is a chronic inflammatory disorder that associates a high risk of progression to mycosis fungoides. 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

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
