We presented a rare case of caval lobular capillary hemangioma.
A 66-year-old female visited our department complaint with shadow defect in vena cava of right renal hilum appeared on computed tomography for periodically checking 3 years after radical hysterectomy with bilateral ovariectomy. Abdominal computed tomography identified a shadow defect of 35 mm in diameter in the inferior vena cava continuing posteriorly to a 35 mm mass of retroperitoneum. During the total removal of this lesion, we identified the lesion was connected to right ovarian vein. The specimen consisted of microcapillaries which formed reticular structure. Immunostaining of specimens identified positive CD31, CD34, and Factor 8 in all cells. Ki67 antibody was positive at 2-3% of all cells. These findings suggested the tumor was intravenous lobular papillary hemangioma.
This is the first report of intravenous lobular papillary hemangioma originated from right ovarian vein and extended to inferior vena cava.
我们报告了一例罕见的腔静脉小叶状毛细血管瘤病例。
一名66岁女性因子宫根治性切除加双侧卵巢切除术后3年定期复查，行计算机断层扫描时发现右肾门腔静脉出现阴影缺损，遂来我院就诊。腹部计算机断层扫描显示下腔静脉有一个直径35毫米的阴影缺损，向后延续至一个35毫米的腹膜后肿块。在完全切除该病变过程中，我们发现该病变与右卵巢静脉相连。标本由形成网状结构的微毛细血管组成。标本免疫染色显示所有细胞的CD31、CD34和因子8均为阳性。Ki67抗体在所有细胞中的阳性率为2%-3%。这些发现提示该肿瘤为静脉内小叶状乳头状血管瘤。
这是首例起源于右卵巢静脉并延伸至下腔静脉的静脉内小叶状乳头状血管瘤的报告。
