Successful treatment of cutaneous solid type adenocarcinoma with cryosurgery in a Pekingese dog

The aim of this study is to defined the treatment of cutaneous solid type adenocarcinoma in a Pekingese dog using cryotherapy. A 3.5 years old intact female Pekingese dog was referred to the small animal surgery clinic. The first neoplasm localization was dorsal to the vulva and the others were bilateral to the vulva. The shape of the nodules were circular. The nodule diameters were 1.8, 1.5, and 1.2 cm. In cross section, the nodules were whitish-yellow in colour, of solid consistency, and characterized by thickening of the skin. The probe-based cryosurgical system was used for cryoablation, using local anesthetic as the interface for uniform freezing. Based on histopathological features, the dog was diagnosed with solid type perianal adenocarcinoma.  In conclusion, cryosurgery can be a potent alternate treatment for pleasant, nodular perianal cutaneous adenocarcinoma in animals, particularly those  not suited for operation, or whose owners refuse to have them undergo operation.
