We report a case of extrauterine epithelioid trophoblastic tumor (ETT)-the rarest variant of gestational trophoblastic tumor-that has been stable on nearly two years of pembrolizumab treatment. A 47-year-old gravida 2, para 2 who underwent a prophylactic bilateral salpingo-oophorectomy nine years prior and bilateral mastectomy five years prior in the setting of a strong family history of breast and ovarian cancer with no genetic testing performed, presented to an outside clinic with recurrent respiratory infections without resolution despite antibiotics. Radiology and pathology testing confirmed the ETT diagnosis, including a second opinion from the John I. Brewer Trophoblastic Disease Center of Northwestern University's Feinberg School of Medicine, and the patient was started on a chemotherapy regimen of etoposide, methotrexate, actinomycin-D, etoposide, and cisplatin for seven cycles, with partial improvement in her disease. After PD-L1 testing showed the tumor had > 5% PD-L1 positivity, she initiated pembrolizumab in April 2019. CT imaging after three months revealed decreased lung, abdominal, and pelvic disease and she was continued on pembrolizumab. As of December 2020, she had completed 29 cycles of pembrolizumab, with a plan for her to continue treatment indefinitely given her decreased, but persistent, disease. Our findings suggest pembrolizumab is a reasonable option for treatment of patients with significant PD-L1 positivity on testing of the tumor.

Isthmoceles are defects related to Caesarean section (CS) scars, known to cause secondary infertility and interfere with in-vitro fertilization in women who have had Caesarean deliveries. The etiologies are multifactorial. Isthmoceles, similar to dehiscent CS scars, can be potential sites for ectopic pregnancies and abnormal placentation.

Objectives: To audit outcomes of patients registered in the Queensland Trophoblast Centre (QTC) database who develop resistance to primary chemotherapy. To determine any risk factors that may predict first-line chemotherapy resistance in patients diagnosed with gestational trophoblastic neoplasia (GTN).
Methods: Patients within the QTC who were diagnosed with GTN between January 2012 and December 2020 were reviewed.

Neoplasms are only sporadically reported in New World primates and rarely in owl monkeys (), specifically. Previous reports of neoplasms in owl monkeys are primarily restricted to lymphoma induced by infection, although other tumors in the central nervous, genitourinary, gastrointestinal, and endocrine systems have been sporadically reported. Herein, we describe 3 previously unreported neoplasms in owl monkeys () including a pericardial mesothelioma in a 6-year-old male, a nephroblastoma in a 2-year-old male, and a cervical neoplasm with characteristics of an epithelioid trophoblastic tumor in a 4-year-old female, all occurring in the same closed breeding colony at a research facility in central Texas.

Objectives: To describe clinical outcomes and pearls for patients with gestational trophoblastic neoplasm (GTN).
Methods: Patients with GTN treated at a referral center from 1/2006 to 12/2022 were included. Clinical characteristics, World Health Organization risk score (low-risk 0-6, high-risk ≥7), and treatments/outcomes were evaluated using summary statistics, stratified by initial treatment at a referral center versus locally.
