Plexiform angiomyxoid myofibroblastic tumor of the stomach: A case report.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a rare mesenchymal tumor of the stomach. To date, about 40 cases of PAMT have been reported in the literature. This tumor is not specific in clinical manifestations and microscopically characterized by a plexiform growth pattern. Here, we report the case of an 11-year-old male patient who was diagnosed with PAMT. He had a complaint of right epigastric discomfort with episodic pain, gastroscopy displayed a submucosal bulge at the pylorus, and CT showed a mass in the right abdomen with uneven, delayed enhancement, and a partial gastrectomy revealed a tumor at the pylorus. Histologically, the tumor was multinodular and rich in blood vessels with thin wall; the interstitium had abundant myxomatous stroma; the tumor cells were spindle-shaped, star-shaped, or oval. Immunohistochemically, the tumor cells were positive for Calponin, Caldesmon, and SMA, but negative for CD34, ALK, S-100, desmin, CD117, and Dog-1. This patient was followed up for 12 months, and recurrence or metastasis was not observed. Diagn. Cytopathol. 2017;45:55-58. © 2016 Wiley Periodicals, Inc.

Clinical study of Coronary artery bypass grafting in the elderly / 中国基层医药

Objective To explore the characteristics of operation,curative effects and operative management in elderly patients of age older than 70 years with coronary heart disease receiving coronary artery bypass grafting.Methods 108 elderly patients of age older than 70 years with coronary heart disease were divided into two groups:OPCAB group(n = 76) and CCABG group (n = 32) The clinical curative effects, early postoperative mortality and complications of the two groups were compared and analyzed respectively. Results OPCAB group was better than CCABG group in these series(P ＜ 0.05): The early postoperative mortality (5.8%, 11.2%)、 myocardial infarction (2.9%, 10.6%), respiration failure(8.7%, 17.5%), pulmonary complications: (11.8%, 31.5%) 、complication of CNS:(1.8% ,9.8%) 、acute renal failure(1.8% ,6.2%) ,the time of intubation: (9.3 ±4.5), (25.4 ±7.5) h,ICU stay(3.1 ± 1.8) ,(7.1 ±2.9) d,hospital stay(15.5 ±8.6) ,(26.4 ±8.6)d. Conclusion OPCAB could reduce operative mortality and complication, it should be the first option for the surgery of elder patients with coronary heart disease;surgical skills and correct perioperative management were the key factors to assure surgical outcome.
