Plain-English summary
A 7-year-old mixed-breed dog and a 9-year-old Labrador were diagnosed with malignant rectal melanoma, a type of cancer affecting the rectum. Both dogs showed signs of discomfort and had tumors that were growing aggressively. The diagnosis was confirmed through specialized tests on tissue samples. Treatment options for this type of cancer can vary, and it's important for pet owners to discuss the best course of action with their veterinarian. Early detection and intervention are crucial for improving outcomes in dogs with this condition.

Abstract
Two rare cases of malignant rectal melanoma in dogs are described. Tumors were locally invasive and composed of spindle cells arranged in interweaving bundles, sheets, and nests within preexisting fibrovascular stroma. Mitotic count was high. The diagnosis was achieved based on histopathology and immunohistochemistry for PNL2 and melan-A.
