A 9-year-old Thoroughbred mare was examined because of pollakiuria, hematuria, and weight loss of 3 weeks' duration. Physical examination revealed a regular cardiac rhythm with occasional premature contractions, and a soft tissue mass in the pelvic canal palpable per rectum. Microscopic examination of urine sediment revealed numerous RBC and a large population of lymphocytes and lymphoblasts with characteristics of neoplasia. Similar cells were found in peritoneal fluid obtained by abdominocentesis. The horse was euthanatized without treatment. Necropsy revealed a soft tissue mass infiltrating the bladder, vagina, and uterus. Additional masses were found in the sublumbar muscles and myocardium. The histologic diagnosis was lymphosarcoma.
一匹9岁的纯种母马因尿频、血尿和持续3周的体重减轻而接受检查。体格检查发现心律正常，偶有早搏，直肠检查可触及盆腔内的软组织肿块。尿液沉渣显微镜检查发现大量红细胞以及大量具有肿瘤特征的淋巴细胞和淋巴母细胞。在通过腹腔穿刺获得的腹腔积液中也发现了类似细胞。这匹马未经治疗即实施安乐死。尸检发现一个软组织肿块浸润膀胱、阴道和子宫。在腰下肌肉和心肌中还发现了其他肿块。组织学诊断为淋巴肉瘤。
