Three cases of primary mediastinal trophoblastic teratoma are described. One patient died from respiratory failure during the initial chemotherapy, Another patient with advanced disease is now apparently free from disease after multiple-drug chemotherapy. The third patient is alive and well four years after a combination of surgery, radiotherapy, and multiple-drug chemotherapy. In the diagnosis...

INTRODUCTION Teratoma refers to a neoplasm that recapitulates all three germ layers. Teratomas may be histologically mature and oncologically benign. Teratomas may also be histologically immature while being oncologically benign, or they may harbor malignant components and have the potential to exhibit an aggressive biological behavior. Teratomas of the head and neck are extremely rare and usua...

Ependymoma is a type of glial tumor that arises from the ependymal lining of the ventricular system of the central nervous system. These tumors may present as a rare extraspinal variety at the sacrococcygeal region, and may be misdiagnosed as pilonidal disease in the post-sacral area or present with mass-effect symptoms on the bowel or bladder in the pre-sacral region. This is a case of soft ti...

Background: Immature teratomas of the ovary represent less than 1% of all ovarian teratomas. Growing teratoma syndrome is an increase of tumor size containing a mature teratoma component, during or after chemotherapy for

To clarify the role of ovarian teratomas in the pathogenesis of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis, we examined histopathologically ovarian teratomas with and without encephalitis as well as normal ovaries. We found strong expression of N-methyl-D-aspartate receptor subtype 2B (NR2B) epitopes in the cytoplasm of oocytes obtained from human and bovine ovaries. A substantial ...
