Plain-English summary
A 7-year-old Black Russian Terrier was brought to the vet because he had been limping on his right front leg and losing weight. During the exam, the vet found a dark mass on one of his toes. To treat this, the vet amputated the affected toe and sent it for testing. The results showed that the mass was a rare type of cancer called biphasic malignant melanoma adenocarcinoma. Unfortunately, this type of cancer can be aggressive, and further treatment options would need to be discussed with the veterinarian.

Abstract
A 7-y-old Black Russian Terrier dog was evaluated for chronic lameness of the right forelimb and concurrent weight loss. Clinical examination revealed a pigmented mass arising from digit 4 of the right forelimb; the digit was amputated and submitted for histologic evaluation. Histologically, the neoplasm was composed of ill-defined streams, sheets, and clusters of melanocytes admixed with a distinct population of malignant epithelial cells forming glands and nests. The diagnosis was a biphasic malignant melanoma adenocarcinoma, a rarely reported neoplasm in human medicine that has not been described in veterinary medicine, to our knowledge.
