(1) Background: Various cutaneous adverse drug reactions (ADRs) are observed with the implementation of mRNA COVID-19 vaccines. To gain insight into the clinicopathologic features, we analyzed the correlation of histological and clinical data in 48 p...
Cutaneous nocardiosis is a rare bacterial infection that can result in various dermatologic manifestations such as actinomycetoma, lymphocutaneous infection, superficial skin infection, and secondary infection due to hematogenous dissemination. We re...
Hand, foot, and mouth disease (HFMD) is a common infectious disease caused by enteroviruses. Coxsackievirus A6 (CV-A6)-associated HFMD has recently emerged as a predominant disease worldwide. Here, we describe five HFMD cases caused by CV-A6 in Japan...
Toxic epidermal necrolysis (TEN) is a rare life-threatening mucocutaneous reaction characterized by epidermal detachment. Treatment success relies on early diagnosis, rapid withdrawal of the causative drug and supportive care. However, clinical evide...
Swine vesicular disease (SVD) is a contagious viral disease of pigs clinically indistinguishable from other vesicular diseases, such as foot and mouth disease, vesicular stomatitis, vesicular exanthema of swine, and idiopathic vesicular disease. In I...
Introduction: Syphilis is a sexually transmitted disease with variable symptoms, often imitating various other disorders. Syphilis progresses through primary, secondary, latent, and tertiary stages, each with distinct clinical manifestations. A sudde...
Human leukocyte antigen (HLA) encoded by the HLA gene is an important modulator for immune responses and drug hypersensitivity reactions as well. Genetic polymorphisms of HLA vary widely at population level and are responsible for developing severe c...
Introduction: Scarlet fever is an acute infectious disease that is characterized by development of characteristic pin-point exanthema in a patient with signs of streptococcal pharyngitis and tonsillitis. Nowadays, due to effective antibacterial treat...
Currently, Brazil lives a triple arboviruses epidemic (DENV, ZIKV and CHIKV) making the differential diagnosis difficult for health professionals. Here, we aimed to investigate chikungunya cases and the possible occurrence of co-infections during the...
Hand, foot, and mouth disease (HFMD) is a mild exanthematous, febrile disease, but it also remains a threat to global public health. HFMD is characterized by a brief febrile illness in children and with a typical skin rash of the hand and foot, with...
Drug hypersensitivity reactions (DHRs) are a type of adverse drug reactions with heterogeneous pathophysiological mechanisms and a broad spectrum of clinical manifestations. Since over-diagnosing is common in children, a complete allergy work-up is n...
Background: Central retinal artery occlusion (CRAO) is an ophthalmic emergency attributed to a vessel occlusion with an embolus or a thrombus and may occur during the hypercoagulable state, inflammation, or vasculitis. CRAO may occur in children; how...
