- Primary atrial fibromyxosarcoma with multiple-system metastases: A case report. [Case Reports]
- MMedicine (Baltimore) 2017; 96(49):e8930
- CONCLUSIONS: Cardiac fibromyxosarcoma is a rare primary malignant cardiac neoplasm, probably with systemic metastases. The possibility of malignancy should be considered as differential diagnosis for cardiac mass.
- A longevity study with enhancer substances (selegiline, BPAP) detected an unknown tumor-manifestation-suppressing regulation in rat brain. [Journal Article]
- LSLife Sci 2017 Aug 01; 182:57-64
- CONCLUSIONS: Considering of the safeness of the enhancer substances and the finding that DEP and BPAP, specific markers of unknown enhancer sensitive brain regulations, detected the operation of an enhancer-sensitive TMS-regulation in rat brain, it seems reasonable to test in humans low dose DEP or BPAP treatment against the spreading of a malignant tumor.

A 65-year-old man presented with giant orbital myxofibrosarcoma with no extraorbital extension. Imaging was suggestive of mesenchymal malignancy with significant vascularity. Incisional biopsy was suggestive of low-grade fibromyxoid sarcoma. The clinical and imaging features did not support the pathological diagnosis. Histopathology of the exenterated sample revealed features of high-grade myxofibrosarcoma. To the best of our knowledge, this is the largest reported myxofibrosarcoma of the orbit. Adjuvant radiotherapy was advised. Correlating the case history, imaging and histopathology, this case can best be summarised as a natural history of conversion from a low to high-grade myxoid malignancy. We emphasise that the overlapping features of myxoid malignancy (fibromyxosarcoma vs myxofibrosarcoma) and regional variation in tumour morphology in biopsy specimen may mislead the clinician. Therefore, knowledge about the key differentiating features as well as incisional biopsy of each radiologically different area can increase the possibility of correct diagnosis and management of each case.

This article presents the unusual case of a 58-year-old woman with a low-grade cardiac fibromyxosarcoma which was primarily surgically resected and treated with adjuvant chemotherapy. A pulmonary metastasis as well as osteolytic metastatic destruction of the right iliac crest occurred 3 years after primary diagnosis and 2 years later a bone metastasis of the left distal femur was detected. Applying a palliative treatment concept resection of the pulmonary metastasis and an extralesional resection of the bone metastasis of the right iliac crest with plastic reconstruction were performed. Afterwards resection of the left distal femur metastasis and prosthetic reconstruction with distal femur replacement could also be realized. Despite an initial poor prognosis a high quality of life without essential functional limitations could be maintained for more than 6 years in this individual case.

Undifferentiated sarcoma is an uncommon primary malignant tumor of the liver typically occurring in older children. It is also referred to as malignant mesenchymoma, fibromyxosarcoma, or mesenchymal sarcoma. We experienced a case of undifferentiated sarcoma in 72-year-old male. Contrast enhanced liver CT scan revealed a 3.4 cm heterogeneously enhancing, ill-defined, and low attenuated mass in the left liver and subtle intrahepatic duct dilatation. And, in tubogram, there were segmental stenosis and occlusion from the hilum to the proximal common bile duct. We did ultrasonography guided liver biopsy. The pathologic finding revealed infiltrative growth of atypical cells with rhabdoid features. Some atypical cells showed clear cytoplasm, but no organoid pattern was identified. The stroma around atypical cells was filled with eosinophilic hyaline material. These tumor cells were positive for vimentin only, and the tumor was consistent with undifferentiated sarcoma of the liver.

Spindle cell carcinoma of larynx is rare tumors constituting only 0.6% of laryngeal neoplasm with predominance in elderly males (average 63 yrs). These tumors were described under various names: pseudosarcoma, Carcinosarcoma, fibromyxosarcoma, mixed sarcoma, polypoidal sarcoma. Immunohistochemistry and electron microscopy suggest that spindle cell carcinoma are true neoplasm and spindle cells are part of the neoplasm and not benign reactive fibroblast.

Dermatofibrosarcoma protuberans (DFSP) is a nodular cutaneous mesenchymal tumor of intermediate malignancy. Studies on fine-needle aspiration of DFSP are extremely rare; to our knowledge, only 33 cases have been reported. We have reviewed 14 examples of DFSP in 13 patients. Ten primary tumors were aspirated before surgical biopsy and four recurrent lesions (all from superficial lesions) were also investigated by fine-needle aspiration. All smears were surprisingly homogeneous and composed of isolated spindle cells in all cases (one unsatisfactory smear is excluded). Tissue fragments with a stroriform pattern were seen in 11 cases, fibrillary stromal fragments in 10 cases, naked nuclei in 8 cases, slight to moderate cytonuclear atypia in 5 cases. Mitotic figures, myxoid background, mast cells, and dispersed adipocytes were rare. Giant cells, necrosis, or marked cytonuclear atypia were not seen. DFSP shares morphological characteristics of some low-grade spindle-cell neoplasms. It should be differentiated from other benign low- and intermediate-grade spindle neoplasm such as low-grade fibrosarcoma, fibromyxosarcoma, low-grade malignant peripheral nerve sheath tumor, benign peripheral nerve sheath tumor, nodular fasciitis, and fibrous histiocytoma.

The relationship between immunosuppression and oncogenesis can be determined by studying the molecular interactions between tumor-inducing viruses and lymphocytes. We approached this study by using a unique system of two genetically related Leporipoxviruses, malignant fibroma virus (MV), and Shope fibroma virus (SFV). MV induces a syndrome of a highly lethal, disseminated myxosarcoma, severe immune suppression, and replicates in lymphocytes both in vivo and in vitro. In contrast, SFV causes a benign fibromyxosarcoma without immune dysfunction and cannot replicate in lymphocytes. Earlier studies demonstrated that transfer of a 10.8-kb Bam HI piece of MV (fragment "C") to SFV resulted in the ability of SFV to replicate in lymphocytes and suppress immune function. These results suggested that lymphocytotropic replication and immune suppression was located on the left side of fragment C. We extended these studies by generating families of recombinants between MV and SFV by using subfragments of fragment C. The resulting recombinant viruses were analyzed for their ability to replicate in lymphocytes, suppress immune function, and produce tumors. Those recombinants expressing MV-like characteristics were mapped by endonuclease digestion. This study demonstrates that recombinants containing a 3.6-kb Nde I subfragment, as well as those containing an overlapping 1.9-kb Hinc II subfragment, were capable of replicating in lymphocytes, suppressing immune functions, and inducing disseminated tumors in rabbits. Our study has therefore identified a portion of MV DNA sufficient to transfer the unique pathogenicity of MV to SFV, and suggests that control of immune suppression and tumor dissemination may not necessarily be mediated by the same viral genes.
