Abstract
This case report presents a rare instance of a 73-year-old male diagnosed with a yolk sac tumor (YST) coexisting with adenocarcinoma components in the stomach. YSTs are primarily gonadal and seldom occur in extragonadal sites such as the gastrointestinal tract. The patient underwent curative resection followed by chemotherapy, resulting in long-term survival without recurrence. This case contributes to the limited existing literature on gastric YSTs, emphasizing the importance of early diagnosis and effective treatment for this aggressive malignancy. It serves as a valuable addition to our understanding of the pathophysiology, diagnosis, and management of this rare condition.

Abstract
Endodermal Sinus tumor is a rare malignant type of germ cell tumor (GCT). Primary endodermal sinus tumor, especially in the head of pancreas, is extremely rare. The case under consideration is of a 22 year old male who presented with pancreatic mass causing postprandial nausea and vomiting, and raised AFP levels. The biopsy of the mass revealed the endodermal sinus tumor, and the pancreatic origin was confirmed by a CT scan and a negative scrotal ultrasound. As the tumor was unresectable initially, a gastrojejunostomy was done to relieve the obstructive symptoms. Whipple procedure was performed two months after 4 cycles of BEP chemotherapy to remove the residual tumor in pancreas. It is crucial to highlight this uncommon case in order to increase surgeons' and oncologists' knowledge of the malignant extra-gonadal GCTs diagnosis and treatment.

Abstract
Yolk sac tumor (YST) is a rare malignant type of germ cell tumor (GCT). Extragonadal yolk sac tumor is a very rare entity. We report the case of a 33-year-old male with a pancreatic mass, which proved to be a primary yolk sac tumor, arising in the pancreas.

Abstract
Background Gastric yolk sac tumor (YST)-like carcinoma is extremely rare, and its prognosis is poor, because most patients have widespread metastases at the time of diagnosis. We report a case of gastric YST-like carcinoma with an adenocarcinoma component without metastases in which curative resection was performed. Case presentation A 77-year-old man complaining of melena and dizziness due to anemia was diagnosed with poorly differentiated adenocarcinoma in the gastric cardia, with a benign ulcer in the gastric body. He underwent total gastrectomy with D2 lymph node dissection for the tumor. Histological examination of the resected specimens revealed a mixture of reticular and glandular neoplastic components morphologically. In the reticular area, an endodermal sinus pattern and some Schiller–Duval bodies were confirmed. Gastric YST-like carcinoma with adenocarcinoma components, T2N0M0 Stage IB, was diagnosed. Immunohistochemical analysis showed that the YST was positive for carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP) and p53. In contrast, the adenocarcinoma was positive for p53 and negative for CEA and AFP. The patient remained healthy as of 7 years postoperatively, with no recurrence. Conclusions Routine medical examinations or endoscopic examinations for accidental symptom may be helpful for early diagnosis and good prognosis for gastric YST-like carcinoma, although the prognosis is generally poor.

Chemotherapy 2016; 62:54-57.

Abstract
The most common sites for extragonadal germ cell tumors are the midline mediastinum, retroperitoneum and, much less frequently, the stomach. The stomach-originated primary germ cell tumor carries a poor prognosis, especially when metastasis occurs to the liver, with a mean survival time of 1 month. We describe the case of a 77-year-old male who presented with usual symptoms of gastric malignancy. Gastrectomy was performed. Histopathology of surgically resected tissue revealed a mixture of adenocarcinoma and endodermal sinus tumor components with α-fetoprotein production. After liver metastasis was identified, oxaliplatin and capecitabine were administered as palliative chemotherapy. The response was poor. For the second-line therapy, bleomycin, etoposide, and cisplatin (BEP) therapy was initiated. The overall response to these drugs was a partial response and the residual liver lesion was considered to be resectable. The patient died of pneumonia 11 months following the BEP session, representing an overall survival time of 22 months. Gastric adenocarcinoma with a germ cell tumor component is uncommon and an effective combination of chemotherapeutic agents is not yet clear. In this case, the patient received germ cell tumor-targeting chemotherapy and showed a durable response. Hence, germ cell-targeting cytotoxic agents have potential as the 'front-line regimen'.
