Classical Presentation of Disseminated Blastomycosis in a 44-Year-Old Healthy Man 3 Months After Diagnosis of COVID-19.

BACKGROUND During the COVID-19 pandemic, the incidence of opportunistic infections, including fungal infections, has increased. Blastomycosis is caused by inhalation of an environmental fungus, Blastomyces dermatides, which is endemic in parts of the USA and Canada. This case report is of a 44-year-old man from the American Midwest who presented with disseminated blastomycosis infection 3 months following a diagnosis of COVID-19. CASE REPORT Our patient initially presented to an outpatient clinic with mild upper-respiratory symptoms. He tested positive for SARS-CoV-2 via polymerase chain reaction (PCR). Three months later, he presented to our emergency department due to some unresolved COVID-19 symptoms and the development of a widely disseminated, painful rash of 1-week duration. A positive Blastomyces urine enzyme immunoassay was the first indication of his diagnosis, which was followed by the identification of the pathogen via fungal culture from bronchoscopy samples and pathology from lung and skin biopsies. Given the evidence of dissemination, the patient was treated with an intravenous and oral antifungal regimen. He recovered well after completing treatment. CONCLUSIONS The immunocompetent status of patients should not exclude disseminated fungal infections as a differential diagnosis, despite the less frequent manifestations. This is especially important when there is a history of COVID-19, as this may predispose once-healthy individuals to more serious disease processes. This case supports the recent recommendations made by the U.S. Centers for Disease Control and Prevention (CDC) for increased vigilance regarding fungal infections in patients with a history of COVID-19.

Hand Dermatitis in the Time of COVID-19: A Review of Occupational Irritant Contact Dermatitis.

Occupational contact dermatitis accounts for 95% of all cases of occupational skin disease with irritant contact dermatitis (ICD) constituting 80% to 90% of these cases. Health care workers, hairdressers, and food service workers are typically most affected by occupational ICD of the hands as these occupations require frequent hand hygiene and/or prolonged exposure to water, also known as "wet work." In the context of the current COVID-19 pandemic, frequent hand hygiene has become a global recommendation for all individuals, and new workplace guidelines for hand sanitization and surface sterilization are affecting occupations not previously considered at risk of excessive wet work including grocery or retail workers, postal workers, sanitization workers, and others. In this review, we discuss the etiology and pathogenesis of occupational ICD with additional focus on treatment and interventions that can be made at an institutional and even national level for education and prevention of ICD resulting from frequent hand hygiene.
