Lichen planus is a common dermatological condition. It is described as a chronic inflammatory mucocutaneous disease that has characteristic clinical and histopathological findings. Classical lichen planus lesions occur as purple, pruritic polygonal papules or plaques with a lace-like pattern of whitish markings on the surface. Despite the large number of variants that exist with different clinical manifestations from the classic form, histopathology features are fairly similar among the subtypes and can aid in the diagnosis. Although most cases of lichen planus are often self-limiting with spontaneous resolution expected within one to two years, early diagnosis and treatment are encouraged to control severe pruritus and painful mucosal erosion, but most importantly to minimize the potential for malignant transformation in long-standing lesions. The main objective of this paper is to report the first case of five cutaneous variants of lichen planus occurring simultaneously in a young male patient.
Miliaria is a self-limiting cutaneous disease that may develop from skin exposure to humid climates, occlusion, or raised temperatures, forming groups of 1-3-mm-sized sweat-filled vesicles in the epidermis due to obstruction of the eccrine sweat duct. Here, we describe the first case of extensive bullous miliaria reported in a 47-year-old female with no comorbidities or significant medical history.
Palisaded neutrophilic and granulomatous dermatitis (PNGD) is a rare reaction pattern that is frequently linked to several systemic diseases, including autoimmune disease, inflammatory bowel disease, and vasculitis. Churg-Strauss syndrome (CSS) is an uncommon systemic condition that occurs exclusively in patients with asthma or a history of atopy. It is characterized by extravascular necrotizing granuloma and hypereosinophilia. This case report describes an illustrative case of a 61-year-old Bahraini female who had been diagnosed with CSS and presented with PNGD. The PNGD appeared a few weeks after her oral corticosteroid medication was discontinued. The present case report aims to assist in accurately diagnosing PNGD, as rarely manifested in this case, thus aiding clinicians in improving patient care.
Atrophoderma of Pasini and Pierini (APP) is a rare cutaneous condition of unknown etiology, predominantly affecting young women. It is a dermatologic disorder characterized by hyperpigmented depressed patches of dermal atrophy. Patients usually present with single or multiple asymptomatic, violaceous, and sharply demarcated areas of depressed plaques; of note, unlike morphea, there is no surrounding erythema or induration. In this report, we discuss a case of a 43-year-old South Asian male patient who presented with an eight-month history of multiple asymptomatic, and depressed bluish-brown plaques that had appeared over his body. The clinicopathological correlation was consistent with a diagnosis of idiopathic atrophoderma of Pasini and Pierini (IAPP). We also engage in a review of the literature on IAPP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
