Abstract
A pet rat (Rattus novergicus) was diagnosed with sarcoma after cytologic and histologic evaluation of a subcutaneous, ventrally-located abdominal mass. Immunohistochemistry revealed neoplastic cells positive for Iba-1 and CD204, indicating a final diagnosis of histiocytic sarcoma. The tumor was aggressive and spread in a few weeks, leading to humane euthanasia.
