Didactics-Metastatic Tumors to the Ovary

Video Transcription

Video Summary

In this video, the speaker discusses tumors metastatic to the ovary. They begin by briefly reviewing primary ovarian tumors and their cell of origin, including epithelial, germ cell, and sex-cord stromal tumors. They then focus on metastatic tumors, which make up approximately 5% of all ovarian tumors. These tumors can be classified as either metastatic or secondary, depending on whether they spread from distant or adjacent sites. However, this distinction is considered artificial as all of these are metastatic tumors. The most common primary sites of tumors that spread to the ovary include the colon, appendix, stomach, and breast. The speaker presents several cases to illustrate different types of metastatic tumors, such as colon carcinoma, gastric carcinoma (known as Krukenberg tumor), breast carcinoma, melanoma, carcinoid tumor, and lymphoma. Immunohistochemical stains are used to confirm the primary site of these tumors. The speaker concludes by mentioning the diagnostic challenge of differentiating metastatic tumors from primary ovarian tumors or synchronous primaries, particularly in cases of endometrial carcinoma metastasis.
