Locally invasive melanoma in the internal laminae of the hoof of a bay mule.

Summary: An 8‐year‐old bay mule was presented with moderate right forelimb lameness and dark discolouration of the white line. Histopathology of the dark material indicated a melanoma. Extensive resection and debridement were not curative and the mule was subjected to euthanasia 70 days after presentation. [ABSTRACT FROM AUTHOR]
