This case report describes the clinical and histopathological findings of an infection caused by equine herpesvirus-1 (EHV-1) in a horse showing respiratory signs and a papular, crusted and ulcerative dermatitis involving mucosae. This diagnosis was supported by real-time PCR positive for EHV-1 on nasal swabs and tissues.

Case Summary: A 9-year-old male castrated domestic shorthair cat from northern California was evaluated for a 12-month history of dermal and subcutaneous dermatitis in the inguinal region. Histopathologic examination of a biopsy revealed severe, chronic, multifocal to coalescing pyogranulomatous dermatitis and panniculitis, accompanied by ulceration and central necrosis. Aerobic bacterial culture of lesions yielded mycobacterial growth.

Rationale: Steven-Johnson syndrome (SJS) is characterized by severe illness, rapid progression, and high mortality rates, with the vast majority of cases induced by medications. Botulinum toxin, a neurotoxin produced by Clostridium botulinum, has not been reported in the literature as a causative agent of SJS.
Patient Concerns: A 56-year-old male patient, who underwent surgery for cerebral hemorrhage, developed widespread patchy annular papules following the injection of botulinum toxin into the masseter muscle.

Ionizing radiation on the skin has the potential to cause various sequelae affecting quality of life and even leading to death due to multi-system failure. The development of radiation dermatitis is attributed to oxidative damage to the skin's basal layer and alterations in immune response, leading to inflammation. Past studies have shown that [18F]F-2-fluoro-2-deoxyglucose positron emission tomography-computed tomography ([18F]F-FDG PET/CT) can be used effectively for the detection of inflammatory activity, especially in conditions like hidradenitis suppurativa, psoriasis, and early atherosclerosis.

Background: Ecthyma is a deeper form of impetigo involving the epidermis and dermis causing ulcerative plaques. Pathogens commonly responsible for the disease (group A beta-hemolytic streptococcus and Staphylococcus aureus) typically afflicts children, presenting during early stages with skin lesions that can closely resemble other vesicular and ulcerative dermatoses, such as those observed in mpox infection. The ongoing global outbreak of monkeypox has escalated the urgency for clinicians to accurately differentiate between these conditions due to their overlapping dermatological manifestations.

Background: Allergic rhinitis (AR) is a common chronic respiratory disease that can lead to the development of various other conditions. Although genetic risk loci associated with AR have been reported, the connections between these loci and AR comorbidities or other diseases remain unclear.
Methods: This study conducted a phenome-wide association study (PheWAS) using known AR risk loci to explore the impact of known AR risk variants on a broad spectrum of phenotypes.
