During necropsy of two manatees, masses in multiple organs including liver and spleen were identified. They were composed of neoplastic round to spindle-shaped cells, positive for vimentin, Iba-1, lysozyme, and Mac387, consistent with histiocytic sarcoma. One manatee also had an undifferentiated sarcoma that may have arisen from the histiocytic sarcoma.

Objectives: To describe the clinical presentation and clinicopathological findings of dogs with nodular splenic lesions composed of heterogeneous cell components associated with systemic inflammation and to provide information on the outcome after surgical resection.

Materials And Methods: Medical records were searched for dogs with histologically and immunohistochemically characterised nodular splenic lesions with mixed stromal, histiocytic and lymphoid cells and the presence of systemic inflammatory markers at the time of diagnosis.

Results: Four dogs were included, of which three had an undifferentiated splenic stromal sarcoma and one had a splenic leiomyosarcoma.

Histiocytic sarcoma (HS) is a rare yet lethal malignancy with no established standard of care therapies. A lack of pre-clinical models limits our understanding of HS pathogenesis and identification of therapeutic targets. Canine HS shares multiple clinical and genetic similarities with human HS, supporting its use as a unique translational model.
