Plain-English summary
A 13-year-old spayed female Australian Cattle Dog had numerous lumps under her skin for over 10 years. Despite tests, the cause of these nodules remained unclear, and an ultrasound showed a small left kidney but no tumors. After she passed away, a thorough examination revealed many firm white masses throughout her body, and her kidneys showed signs of severe damage. This case is unique because it shows nodular dermatofibrosis (a skin condition) occurring without the usual kidney tumors. Unfortunately, the dog did not recover, and the underlying kidney issues contributed to her condition.

Abstract
A 13-year-old, spayed, female Australian Cattle Dog had at least a 10-year history of numerous subcutaneous nodules for which fine-needle aspiration and cytologic evaluation were nondiagnostic. Abdominal ultrasound 3.5 months before necropsy detected a small left kidney but no cysts or neoplasms. At gross necropsy, innumerable, firm, round to oval, white, 0.25 to 2 cm masses were detected throughout the subcutaneous tissues of the axial and appendicular skeleton, epimysium of numerous muscles, and parietal peritoneum of the lateral abdominal body wall. The left kidney was approximately half the size of the right, and there was severe bilateral renal medullary (papillary) necrosis. Histologically, the subcutaneous nodules were well-demarcated masses of mature, hypocellular collagen that were consistent with previous reports of nodular dermatofibrosis and renal cystadenomas or cystadenocarcinomas. In addition to diffuse acute medullary necrosis, both kidneys were affected by severe chronic lymphoplasmacytic interstitial nephritis. This is the first known report of nodular dermatofibrosis in a dog without renal cysts, cystadenoma, or cystadenocarcinoma.
