horse

Plain-English summary

A 6-year-old Haflinger mare was brought in because she had a history of bleeding in her abdomen that kept coming back. When she passed away and was examined, the veterinarians found a firm, yellow mass in the back part of her abdomen. Further testing showed that this mass was made up of a type of cell called fibroblasts, which are involved in tissue repair. Unfortunately, the findings suggest a serious condition, and the treatment options would depend on the specific diagnosis made from these results.

Abstract

A 6-year-old Haflinger mare was presented with a history of recurrent hemoabdomen. On necropsy, a firm infiltrative multinodular yellow mass was observed in the wall of the posterior abdomen. Histopathologic examination revealed a proliferation of fibroblastic cells, which were positive for α-smooth muscle actin and vimentin.
