Abdominal wall mass and hemoabdomen in a Haflinger mare.
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.
