Abstract
This case report presents a rare instance of Eruptive Pruritic Papular Porokeratosis (EPPP) in a 71-year-old Chinese male, emerging on atypical sites (face, scalp, and ears) following a COVID-19 infection, and explores the potential link between viral infections and EPPP onset. The patient's lesions, characterized by annular brown patches with hyperkeratotic ridges, showed significant improvement following treatment with Baricitinib and Acitretin. This case underscores the need for awareness of unusual presentations of EPPP and suggests the potential efficacy of Janus Kinase (JAK) inhibitors in treatment, prompting further research into the pathophysiological connections between EPPP and viral infections. Adherence to the SCARE 2023 guidelines ensures a comprehensive and transparent case presentation.

Abstract
Porokeratosis is a heterogeneous group of keratinising disorders characterised by the presence of particular microscopic structural changes, namely the presence of the cornoid lamella. This structure develops as a consequence of a defective isoprenoid pathway, critical for cholesterol synthesis. Commonly recognised variants include disseminated superficial actinic porokeratosis, disseminated superficial porokeratosis, porokeratosis of Mibelli, palmoplantar porokeratosis (including porokeratosis palmaris et plantaris disseminata and punctate porokeratosis), linear porokeratosis, verrucous porokeratosis (also known as genitogluteal porokeratosis), follicular porokeratosis and porokeratoma. Apart from the clinical presentation and epidemiology of each variant listed, this review aims at providing up-to-date information on the precise genetic background, introduces imaging methods facilitating the diagnosis (conventional and ultraviolet-induced fluorescence dermatoscopy, reflectance confocal microscopy and pathology), discusses their oncogenic potential and reviews the literature data on the efficacy of the treatment used, including the drugs directly targeting the isoprenoid-mevalonate pathway.

Ishikawa M, Yamamoto T. Eruptive superficial porokeratosis in a patient with nephrotic syndrome. An Bras Dermatol 2022; 97:399-400. [PMID: 35321801 PMCID: PMC9133250 DOI: 10.1016/j.abd.2020.08.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 08/08/2020] [Indexed: 11/26/2022] Open
Abstract
A 34-year-old female was referred to our department, complaining of multiple asymptomatic lesions that appeared two weeks previously. The patient had active nephritis with nephrotic syndrome and was treated with immunosuppressive therapies. Physical examination revealed multiple well-circumscribed rounds of flat brownish plaques with slightly elevated borders, some of which were covered by scales. The number of lesions was nine in total. Skin biopsy specimens showed dyskeratotic cells in the thinned epidermis with cornoid lamella, and the absence of a granular cell layer. The development of porokeratosis was considered to be related to immunosuppressive therapy or the activity of nephritis.

Abstract
Porokeratosis is a rare disorder characterized by atrophic macules or patches, with a well-defined ridge-like hyperkeratotic border called cornoid lamella. Although the exact pathogenesis is unknown, drug associated cases have recently been reported in the literature. As such, we systematically reviewed and identified drugs associated with drug-induced porokeratosis, their resultant effects, and whether there was a casual relationship between the use of a drug and the development of porokeratosis. We searched for articles which reported drug-induced porokeratosis in MEDLINE and Embase in June 2020. After full-text review, 25 studies were included for analysis. We identified 26 patients with drug-induced porokeratosis. The most common therapies associated with development of porokeratosis is biologic use, phototherapy, and radiotherapy. The most common clinical variants were the disseminated superficial or actinic types (60%), which occurred in psoriasis patients undergoing phototherapy, and eruptive disseminated type (24%) which occurred in the context of biologic therapies. The Naranjo score ranged from possible to probable for the identified treatments. Clinicians should consider drug reactions as possible triggering events for porokeratosis, especially for patients taking biologics, phototherapy, and radiotherapy. Large-scale studies are required to confirm our findings and further explore the pathogenesis for drug-induced porokeratosis.
