Adenocarcinomas of intestinal type arising in mature cystic teratoma of ovary (MCT) are extremely rare and remain a diagnostic dilemma because of its similarities with MCT. Serum tumor markers CEA and SCC and also MRI may help in the preoperative diagnosis. Pathologist experience helps in intraoperative diagnosis.

Intussusception is a relatively common disease in pediatric age but it is uncommon in adults. We report a case of a 49-year-old male who presented with an acute jejunojejunal intussusception revealed by abdominal pain and vomiting. He underwent an en bloc resection, and pathological findings concluded to a metastasis of a pulmonary combined small cell carcinoma and adenocarcinoma. A subsequent CT scan revealed the primitive mass of the right lung with no evidence of secondary localization. The biopsy was difficult to perform. The patient underwent a pneumonectomy with lymph node dissection confirming the same diagnosis. He made a good recovery from the surgery, and a postoperative chemotherapy was administrated, and he is in remission until this date.

and blood group A was firstly discovered by Aird et al. The study aims to evaluate the cancer distributions and prognostic significance for the HER2 positive gastric cancer.Methods: The data of 112 patients were retrospectively reviewed. The ABO blood groups, clinical, and histopathological data of the patients were recorded. The ABO blood group distributions of the patients were compared to healthy donors (n:130,909) by chi-square test.Results: The median follow-up period was 15.5 months (range: 1.07-81.1 months). The percentages of female and male patients were 29% and 71%, retrospectively. The median age at diagnosis was 61 years (range: 24-91 years). The median OS was 17.9AE2.3 months (13.2-22.5 months). Overall distributions of ABO blood groups were different between patients (57.1% A, 10.7% B, 6.3% AB, 25.9% O) and controls (41.87% A, 15.29% B, 7.91% AB, 34.93% O) (p¼0.013). The distribution of Rh factor was comparable between patients and the control group (p¼0.074). In univariate analysis, ABO blood groups were not a prognostic factor on OS. Conclusion:In this study, we determined to the A blood frequency in HER2 positive gastric cancer is more common than other blood groups. 0 blood groups may be protective for HER2 positive gastric cancer.Legal entity responsible for the study: The authors.
