Plain-English summary
An 8-year-old male Boxer was found to have a skin tumor (mast cell tumor) growing inside a fatty lump (lipoma) on his right side. The tumor was classified as grade I, meaning it was less aggressive. After testing, the vet confirmed the type of cells involved and their behavior. Treatment options would typically include surgical removal of the tumor, and with early detection and treatment, many dogs can recover well.

Abstract
This report describes a case of a canine cutaneous grade I mast cell tumour which developed within a lipoma in the right axillar region of an 8-year-old male Boxer. Immunohistologically, the neoplastic mast cells were positive for serotonin, CD45 vimentin and p53, and negative for lysozyme, CD3 and CD79a expression. The proliferation index of the mast cell tumour based on the Ki-67 antigen was 6.1%. Between the benign neoplastic lipocytes and mastocytoma tumour cells intratumoural microvessels were detected by immunohistochemical staining using CD31 and claudin-5 as markers for vascular endothelium.
