Metastatic perioral melanoma in a wild mountain gorilla (Gorilla beringei beringei).

A 30‐year‐old free‐ranging female mountain gorilla (Gorilla beringei beringei) developed a perioral mass that was surgically debulked and diagnosed as malignant melanoma. After tumor recurrence, a canine melanoma vaccine was administered. However, the gorilla died shortly thereafter, and metastases to lymph nodes, lung, liver, and kidney were found post‐mortem.
