Undifferentiated round cell sarcoma of the broad ligament
Sarcomas of the broad ligament are very uncommon. To our knowledge, there are no cases published of undifferentiated round cell sarcoma of the broad ligament. Round cell sarcomas are a rare and very aggressive variant, which due to their sensitivity to chemotherapy, have an acceptable prognosis. We report the case of a 27-year-old woman who presented with a pelvic mass with a 7-cm diameter plac...
متن کاملDedifferentiated Giant-Cell Tumor of Bone with an Undifferentiated Round Cell Mesenchymal Component
The dedifferentiated giant-cell tumor of the bone is a very rare variant of the giant-cell tumor (GCT). We report the clinical, radiographic and histological findings of a dedifferentiated GCT in which the dedifferentiated component consisted of small round cells. We also comment on previously reported cases of dedifferentiated GCT, discuss the clinical implications of this dual histology, and ...
متن کاملRound - Cell , Spindle - Cell , and Neurogenic Sarcomas O F the Lip
Sarcomas, or tumors derived from the connective-tissue elements, are rare among the malignancies of the lip. The only available statistics as to sarcoma of the lip are from the Gottingen Pathological Institute, where 2 cases were found among 1,248 sarcoma cases (0.16 per cent). No mention was made as to whether the lesions were on the vermilion border, and the type of sarcoma is not specified. ...
متن کاملMacrophage infiltration and genetic landscape of undifferentiated uterine sarcomas.
Endometrial stromal tumors include translocation-associated low- and high-grade endometrial stromal sarcomas (ESS) and highly malignant undifferentiated uterine sarcomas (UUS). UUS is considered a poorly defined group of aggressive tumors and is often seen as a diagnosis of exclusion after ESS and leiomyosarcoma (LMS) have been ruled out. We performed a comprehensive analysis of gene expression...
متن کاملTumor and Stem Cell Biology Hedgehog and Notch Signaling Regulate Self-Renewal of Undifferentiated Pleomorphic Sarcomas
Like many solid tumors, sarcomas are heterogeneous and include a small fraction of the so-called side population (SP) cells with stem-like tumor-initiating potential. Here, we report that SP cells from a soft tissue tumor of enigmatic origin termed undifferentiated pleomorphic sarcoma (also known as malignant fibrous histiocytoma or MFH sarcoma) display activation of both the Hedgehog and Notch...
