Abstract
We report two cases of cutaneous mpox virus infection (formerly known as “monkeypox”), one of which presented with unusual clinical findings, and demonstrate their histopathologic, RNA in situ hybridization and ultrastructural characteristics. We observed in two patients with PCR-confirmed mpox virus infection squamous syringometaplasia of the eccrine ducts, a finding that can aid in recognizing this disease and is explained by the demonstration of viral mRNA within eccrine epithelium by in situ hybridization.
