Large, variably sized, clear vacuoles are present in the cytoplasm of polygonal cells, displacing the flattened nucleus to the periphery of the cell. Interstitial, thecal, and granulosa cells contain numerous lipid droplets. Fatty change may be induced by drugs inhibiting steroid hormone synthesis, resulting in lipid accumulation in the ovarian stroma. Rats treated with an imidazole antifungal drug had increased lipid in the interstitial cells of the ovary, which was also associated with deposition of lipofuscin. ## 英文原文 · Recommendation Ovary - Fatty change should be diagnosed and graded whenever present. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0628.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0624.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
