Abstract：
Microscopic heterotopic extraovarian sex cord-stromal proliferations were first reported in the literature in 2015 by McCluggege. Afterwards, few similar cases have been described. Herein, we report the fourteenth case of microscopic heterotopic sex cord-stromal proliferation and the third case sited in the pelvic peritoneum. The clinical history of these rare cases suggests their benign nature. Knowledge of this histological pattern is important for differential diagnoses such as malignant pathologies and metastatic diseases.
摘要：
McCluggege于2015年在文献中首次报道了卵巢外性索基质的显微异位增生。之后,很少有类似的案例被描述。在这里，我们报告了第14例显微镜下异位性索基质增生，第3例位于盆腔腹膜。这些罕见病例的临床病史表明其良性性质。了解这种组织学模式对于鉴别诊断（例如恶性病理和转移性疾病）很重要。
