Leptospirosis presented with erythema nodosum on four limbs: an unusual presenting.

Leptospirosis is a common disease between humans and animals characterized by a wide range of clinical manifestations. Erythema nodosum (EN) is a common clinical form of panniculitis or subcutaneous adipose inflammation caused by hypersensitivity responses to antigens, but the presence of EN in a subject with leptospirosis is a very rare case presentation. We will present a 42-year-old man with a headache, myalgia, nausea and rigid tender on the shin and both forearms, which was a typical form of EN lesions.
