Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder sometimes accompanied by ovarian teratoma. However, the concept of encephalitis without anti-NMDAR antibodies successfully treated with ovarian teratoma resection and immunotherapy has not been established. We herein report two such cases. Case 1 exhibited delayed magnetic resonance imaging abnormalities in the thalamus and basal ganglia, despite clinical improvement. Case 2 presented with brainstem encephalitis similar to Bickerstaff's encephalitis. Although both patients tested negative for anti-NMDAR antibodies, the recovery of the neurological function and good prognosis following tumor resection with immunotherapy indicated a close association between these diseases and ovarian teratoma.

Background: Ovarian mature teratoma represents the most common benign neoplasm among pediatric germ cell tumors. This study reports the prevalence and characteristics of familial forms identified in a single center over 22 years in order to better understand possible familial predispositions to ovarian teratoma.
Methods: The records of all patients who were surgically treated for ovarian teratoma between 2000 and 2022 were retrospectively reviewed.

Objective: To explore the characteristics and survival outcomes of ovarian squamous cell carcinoma (SCC) and the treatment effectiveness of immune checkpoint inhibitors (ICIs).
Methods: Patients diagnosed with ovarian SCC at Peking Union Medical College Hospital between January 2000 and September 2023 were included. Overall survival (OS) and progression-free survival (PFS) were analyzed using the Kaplan-Meier method.

Background And Aims: Benign ovarian neoplasms are common in the pediatric population. In young adult women, oophorectomy has been shown to negatively impact long-term ovarian endocrine function. Recently, ovarian-sparing surgery (OSS) has been proposed as it offers similar results to oophorectomy in terms of recurrence rates.

Background: Karyotype 46, XY female disorders of sex development (46, XY female DSD) are congenital conditions due to irregular gonadal development or androgen synthesis or function issues. Genes significantly influence DSD; however, the underlying mechanisms remain unclear. This study identified a Chinese family with 46, XY female DSD due to the CUL4B gene.
