A Case of Significant Response to Olaparib in a Patient with Primary Peritoneal Carcinosarcoma Diagnosed by Laparoscopic Surgery

<div>Examination of hematoxylin and eosin-stained sections revealed that the tumor was composed of malignant epithelial elements and sarcomatous elements of spindle cells. (a) The epithelial component displayed the solid proliferation of severely atypical cells, thus mimicking ovarian high-grade serous carcinoma. (b) The stromal component consisted of atypical spindle cells mimicking leiomyosarcoma. Scale bars: (a) 200 <i>μ</i>m and (b) 100 <i>μ</i>m.</div>
