Gastric carcinosarcoma with rhabdomyosarcomatous differentiation: a case report and literature review

Gastric carcinosarcoma with rhabdomyosarcomatous differentiation is a rare tumor. Herein, we report the case of a 34-year-old man with a history of dysphagia, upper abdominal fullness, and poor appetite. Endoscopic findings showed a large friable mass that originated from the gastric cardia and lesser curvature of the high body. Consequently, radical total gastrectomy with Roux-en-Y esophagojejunostomy was performed. Histopathological analysis of the resected specimen revealed that the mass had invaded the serosa without regional lymph node metastasis; moreover, the tumor was positive for desmin and myogenin. Finally, we conclude this report with literature review and discussion

Modified Autonomous Key Management Scheme with Reduced Communication/Computation Costs in MANET

The growing applications of mobile ad hoc networks (MANETs) have made related security issues much more important. B. Zhu et al. proposed a key management scheme using Shamir's secret sharing scheme to construct an Autonomous Key Management (AKM) hierarchy structure. However, Shamir's secret sharing in AKM to control key hierarchy incurs high message transmission costs. This paper modifies the secret sharing scheme and applies it to AKM to reduce communication and computation costs
