    Myxoid hepatocellular adenoma, a rare variant of hepatocellular adenoma with distinct imaging features: A case report with immunohistochemical and molecular analysis and literature review

    Preoperative imaging and histopathology, immunohistochemistry and molecular analysis after resection of 2 hepatocellular adenomas (HCAs) (20 and 2 cm) in a 53-year-old female patient were performed. On imaging, the large lesion resembled a myxoid HCA, while the small lesion resembled a more conventional HCA with a small myxoid/fluid area. On microscopy, the large lesion showed cords and nests of hepatocytes embedded in abundant myxoid matrix, while the small lesion resembled a conventional HCA with small foci of myxoid change and serosities; both consistent with a myxoid HCA. Immunophenotyping and molecular subtyping excluded inflammatory HCA, CTNNB1 mutated HCA and sonic hedgehog HCA, and was consistent with HNF1A mutated HCA. The myxoid change as well as the serosities may allow imaging diagnosis of myxoid HCA. As fluid vacuoles can also be present in ASS1 + HCA, sonic hedgehog HCA has to be considered in the differential diagnosis

    MOSART project addresses two main challenges of prevailing architectures: (i) The global interconnect and memory bottleneck due to a single, globally shared memory with high access times and power consumption; (ii) The difficulties in programming heterogeneous, multi-core platforms MOSART aims to overcome these through a multi-core architecture with distributed memory organization, a Network-on-Chip (NoC) communication backbone and configurable processing cores that are scaled, optimized and customized together to achieve diverse energy, performance, cost and size requirements of different classes of applications. MOSART achieves this by: (i) Providing platform support for management of abstract data structures including middleware services and a run-time data manager for NoC based communication infrastructure; (ii) Developing tool support for parallelizing and mapping applications on the multi-core target platform and customizing the processing cores for the application.
