Vaginal high-grade sarcoma in pregnancy.

BackgroundVaginal cancer is a rare malignancy making up 1-2% of all female genital tract cancers. Among vaginal cancers, sarcomas constitute 2% of malignant vaginal lesions, with leiomyosarcomas being the most common type of sarcoma. There is a paucity of data to guide treatment of vaginal sarcomas. This case report details a patient diagnosed with a gynecologic sarcoma during pregnancy who is subsequently treated for residual vaginal disease in the postpartum period with local resection and adjuvant vaginal brachytherapy.CaseA 31-year-old gravida 4 para 0 who presented at 22-weeks gestation with vaginal bleeding to an outside hospital and expelled a mass 11 cm in diameter from the vagina during her admission. Findings were consistent with a high grade gynecologic sarcoma. She underwent planned cesarean section at 36 weeks gestational age with uterine pathology showing no sarcoma. At her 3 month postpartum visit she was found to have a 1 cm posterior vaginal wall lesion which was resected and consistent with vaginal sarcoma. She underwent adjuvant brachytherapy.ConclusionThis case demonstrates the challenges with obtaining a correct pathological diagnosis for pregnant patients with vaginal sarcoma during pregnancy. Surgical resection with negative margins remains an important treatment component. Given the low incidence of disease occurrence in pregnancy and rare number of cases reported in literature, further elucidation of timing of delivery and adjuvant treatment is warranted

Treatment of metastatic placental site trophoblastic tumor with surgery, chemotherapy, immunotherapy and coil embolization of multiple pulmonary arteriovenous fistulate

Placental Site Trophoblastic Tumor (PSTT) is a rare malignancy that often presents with extensive disease and can be resistant to traditional treatments. We present the case of a woman with stage IV PSTT who was initially managed with neoadjuvant chemotherapy followed by tumor debulking. Adjuvant therapy was guided by further pathologic analysis that revealed high levels of staining for PD-L1 as well as the presence of tumor infiltrating lymphocytes (TILs). Subsequently, the patient was treated with traditional chemotherapy with the EP/EMA regimen with the addition of pembrolizumab. The patient’s treatment course was complicated by the development of pulmonary arteriovenous malformations, autoimmune thyroiditis thought to be secondary to immunotherapy, and significant tinnitus secondary to platinum agents. Currently the patient is in follow up and remains in a complete remission
