An ovarian steroid cell tumor was diagnosed in a 6.5-year-old female Rottweiler. The animal was polydipsic and polyuric, with an enlarged, pot-bellied abdomen. Radiographs and ultrasound examinations revealed an approximately 13-cm-diameter cystic mass below the right kidney. A low-dose dexamethasone suppression test was consistent with hyperadrenocorticism. Surgical exploration revealed an enlarged, lobulated left ovary approximately 10 cm in diameter, weighing 550 gs. Histologically, the ovarian tumor consisted of dense sheets and nests of round to polyhedral cells with abundant, finely vesiculated cytoplasm. The overall features were most consistent with ovarian steroid cells tumor resembling luteoma and associated with hyperadrenocorticism.
一只6.5岁的雌性罗威纳犬被诊断出患有卵巢类固醇细胞瘤。该动物有多饮多尿症状，腹部膨隆增大。X光片和超声检查显示右肾下方有一个直径约13厘米的囊性肿块。低剂量地塞米松抑制试验结果与肾上腺皮质功能亢进相符。手术探查发现左侧卵巢增大呈分叶状，直径约10厘米，重550克。组织学检查显示，卵巢肿瘤由密集的片状和巢状圆形至多面体细胞组成，细胞质丰富且有细微空泡。总体特征与类似黄体瘤并伴有肾上腺皮质功能亢进的卵巢类固醇细胞瘤最为相符。
