Clinical, molecular, and histological characteristics of severely necrotic and fatal mpox in HIV-infected patients.

Background: This case series of 5 patients with severely necrotic mpox highlights the predominantly necrotic nature of lesions seen in cases of severe mpox as shown by skin and lung biopsy, as well as the extensive dissemination of the infection, as shown by polymerase chain reaction (PCR) assessment in different body sites.

Case Presentations: Patients were male, the median age was 37, all lived with HIV (2 previously undiagnosed), the median CD4 cell count was 106 cells/mm, and 2/5 were not receiving antiretroviral treatment. The most common complication was soft tissue infection.

Not all that glitters is COVID-19: a case series demonstrating the need for histopathology when skin findings accompany SARS-CoV-2 infection.

Background: Descriptions of cutaneous findings associated with COVID-19 have not been consistently accompanied by histopathology or confirmatory testing for SARS-CoV-2.

Objective: To describe and classify the cutaneous findings with supporting histopathology of confirmed COVID-19 inpatients.

Methods: We included consecutive inpatients with a confirmed diagnosis of COVID-19 for whom a dermatology consult was requested.
