External caseous lymphadenitis, submandibular lymph node, goat
Lesion of the submandibular lymph node of a goat with the external form of caseous lymphadenitis. Hair is missing from the lesion; however, the lesion is not yet draining, which is why the examiner does not have to wear gloves. The ruler indicates the size of the lesion.
