Expression of proto-oncogene C-kit and correlation with morphological evaluations in canine cutaneous mast cell tumors.
Canine cutaneous mast cell tumor (MCT) is very common disease in dogs, this is more aggressive than in other species. The biologic behavior of MCT is highly variable and a more accurate prognosis for these tumors needs to performed. The proto-oncogene c-kit is known to play a critical role in development and function of mast cells (MC). The aim of this study was to evaluate the expression of immunohistochemical pattern of c-kit in MCTs and to correlate these results with MC density (MCD) and intratumoral microvessel density (MVD). Our results confirm that a more aggressive biologic behavior of canine MCT is associated with the increased c-kit expression, further suggesting a new role for c-kit, as a useful marker, in diagnostic pathology and in tumor progression.
