We present two cases of 10 and 27 years old girls with recurrence of immature teratoma after an incomplete surgical staging. In both cases, there were huge abdominopelvic masses despite decrease in tumor markers with chemotherapy. Complete surgical resection of these masses was done, and histopathology showed only mature teratoma.

Introduction: We present a rare case of long-term survival following metastasectomy for lumbar metastasis with growing teratoma syndrome.
Case Presentation: An 18-year-old man presented with left scrotal mass and lumbago. Alpha-fetoprotein was elevated to 648.

Growing teratoma syndrome (GTS) is characterized by a reduction in serum tumor markers despite the growth of a benign mature teratomatous mass following chemotherapy for germ cell tumors. Gliomatosis peritonei (GP) typically accompanies ovarian teratomas, marked by the dissemination of mature glial tissue across the peritoneum. The concurrent presence of GTS and GP after treatment for ovarian immature teratoma (IMT) is notably rare, with approximately 20 reported cases.

Testicular cancer is one of the leading malignancies affecting young men, with germ cell tumors (GCTs) being the most prevalent type. These tumors are classified into two main subtypes: seminomas and non-seminomatous germ cell tumors (NSGCTs), with the latter known for their higher likelihood of metastasis. Early detection through imaging and tumor markers like alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (HCG) is crucial for favorable outcomes.

Introduction: The rising number of cats as pets and the growing interest in animal welfare have led to an increased need for the latest treatments in feline veterinary medicine. Among these, veterinary regenerative medicine using pluripotent stem cells is gaining significant attention. However, there have been no reports on establishing feline embryonic stem cell (ESC) lines that possess the pluripotent potential and the ability to differentiate into three germ layers.
