Plain-English summary
An 8-year-old female Poodle was diagnosed with a rare type of salivary gland cancer called cystadenocarcinoma, which can look similar to another serious cancer called hemangiosarcoma. The dog had a tumor that contained a lot of red blood cells, making it tricky to identify. Special tests were done to confirm the type of tumor, which showed it was indeed cystadenocarcinoma. This diagnosis is important for determining the right treatment plan.

Abstract
Cystadenocarcinoma is regarded as a rare adenocarcinoma variant in animals. This work reports the case of an 8-year-old female Poodle dog with salivary gland cystadenocarcinoma with morphological characteristics similar to a hemangiosarcoma. Histopathological analysis showed a tumor mass with cystic formations containing a large amount of red blood cells. In order to distinguish these two entities, periodic acid Schiff (PAS) staining and immunohistochemical analysis were carried out with the use of cytokeratin AE1/AE3 (CK) and CD31-specific antibodies. Neoplastic cells were PAS-negative, CK-positive and CD31-negative confirming their epithelial origin. Based on the findings, the diagnosis of high grade cystadenocarcinoma was established.
