Abstract Background: Malignant gastrointestinal neuroectodermal tumor is an extremely rare soft tissue sarcoma which was firstly described in 2003 but until recently it had been designated as a definite new entity. According to the previous literatures, Malignant gastrointestinal neuroectodermal tumor was almost exclusively occurred in gastrointestinal tract.Case presentation: A 62-year-old male showed a mass in right atrium and the occupying mass was founded on the right ventricular diaphragm and involved the right atrium along the coronary sinus during the operation. Microscopically, the tumor characterized by the solid sheet and pseudopapillary focally architectures, and was composed of small to medium cells with round or oval nuclei, variable amount of eosinophilic or clear, and frequent mitotic figures. Immunohistochemically, the neoplastic cells were positive for S100 and SOX-10 but negative for HMB-45, A103 and CD99. EWSR1-AFTF1 rearrangement was detected by fluorescence in situ hybridization and further confirmed involving fusion of EWSR1 exon 8 with ATF1 exon 4 by whole transcriptome sequence analysis.Conclusions: This is the first case report of extra-gastrointestinal Malignant gastrointestinal neuroectodermal tumor that occurring in the right atrium，which remind of the new prospect of the tumor location.

We present a patient with a primitive neuroectodermal tumor arising from the right atrium who experienced multiple syncope episodes daily, which had first appeared 1 month after surgery. The symptoms continued to worsen over the course of chemotherapy, and the autonomic function test (AFT) was performed after the 14th chemotherapy cycle. The AFT revealed orthostatic hypotension and reduced baroreflex-dependent sympathetic reactivity. Physical counterpressure techniques were applied with a visual biofeedback intervention, and were found to be effective in reducing the syncope episodes.

Primary liver sarcomas represent a rare group of neoplasias, with angiosarcoma being the most common histological type. Primitive neuroectodermal tumor (PNET) represents a high malignant neoplasia that usually affects the central nervous system and soft tissues. An 18-year-old male patient was admitted with clinical complains of pain in the right upper abdominal quadrant. The clinical evaluation revealed a solid mass in the right hepatic lobe. On the gross examination of the resected liver specimen, the right lobe of the liver was replaced by a yellow-red solid mass measuring 21 cm in its largest dimension. On the histopathology, a tumor composed of small round blue cells with little cytoplasm and round nuclei was identified. The lesion revealed positive immunoexpression for vimentin and CD99 and negative immunostaining for desmin, CD45, cytokeratin, and neuroblastoma protein, suggesting, then, the diagnosis of PNET. Although it is an unusual tumor, it should be considered in the differential diagnosis of liver masses, especially in young patients.
