  • Title: Nasal tumor with widespread cutaneous metastases in a Golden Retriever.
    Author: Koehler JW, Weiss RC, Aubry OA, Smith AN, Hathcock JT, Brawner WR.
    Journal: Vet Pathol; 2012 Sep; 49(5):870-5. PubMed ID: 21878681.
    Abstract:
    An intact, 8-year-old, male Golden Retriever dog was presented for evaluation of a nasal mass and approximately 30 firm, raised, variably ulcerated dermal and subcutaneous masses. Histopathology of both nasal and multiple skin masses revealed multiple nonencapsulated, infiltrative masses comprising clusters, anastomosing trabeculae, and packets of neoplastic, round to ovoid, hyperchromatic cells with marked nuclear molding. Surrounding the neoplastic cells was a marked stromal response in which many of the spindle-shaped cells expressed muscle-specific actin and had ultrastructural features consistent with myofibroblasts. A literature search indicates that this is the first report in a peer-reviewed journal of cutaneous metastasis of a nasal neuroendocrine tumor in any domestic animal species.
