Which of the following would be an atypical finding in splenic nodules?

In the context of splenic nodules, the presence of fibrosarcoma represents an atypical finding. Splenic nodules can arise from a variety of neoplastic processes and other non-neoplastic conditions.

Granulomas can occur in the spleen as a result of infections, inflammation, or immune-mediated diseases. They are relatively common in splenic pathology due to various etiologies, such as chronic infection or foreign body reaction.

Histiocytic sarcoma is a recognized tumor type in dogs and can commonly present as splenic nodules. It arises from the histiocytic lineage and is a known malignancy associated with the spleen, particularly in certain breeds.

Complex nodular hyperplasia is another condition that may be seen in the spleen, often related to reactive or hyperplastic changes rather than a neoplastic process. It can present as multiple nodules but is still considered within the realm of atypical splenic findings.

Fibrosarcoma, on the other hand, is less commonly associated with splenic nodules. While it can occur anywhere in the body, its presence in the spleen is not typical and suggests an unusual pathologic process. Hence, identifying fibrosarcoma in the context of splenic nodules
