Renal Cystadenocarcinoma in a German Shepherd Dog with Chronic Haematuria

Abstract

A renal and cutaneous hereditary disease which usually occurs in the German Shepherd is primarily expressed as cystadenocarcinoma and collagenous nevi. The skin lesions, also called nodular dermatofibrosis, are the usual presenting complaint, whereas haematuria, renal failure and/or metastatic disease may lead to the death of the animal. This report describes the clinical, imaging and pathologic findings in a 10year-old, male German Shepherd. The dog was admitted because of chronic intermittent haematuria and, despite the removal of the right kidney, eventually developed generalised metastatic disease and was euthanised 15 months later.
