Viruela del mono con afectación de conductos ecrinos

Monkeypox was historically considered a zoonotic disease restricted to areas with an animal reservoir and with limited possibilities of human transmission. However, the recent increase in incidence in non-endemic areas, together with the demonstration of human transmission, has led to more attention being paid to this disease. We present the case of a 27-year-old man with cutaneous lesions and perianal ulcers, clinically suggestive of a viral disease. Monkeypox was demonstrated with PCR analysis. The histological features and differential diagnoses of monkeypox are discussed and the characteristic histopathological pattern of eccrine gland epithelium is described which, if found in an ulcerated lesion, should raise suspicion of monkeypox.
