This study aims to provide the first epidemiological analysis of incidence and survival rates of STS in the Australian population.MethodsA retrospective population-based observational study was conducted between 1982 and 2009 of all patients with a diagnosis of STS using the Australian Institute of Health and Welfare (AIHW) Australian Cancer Database. Incidence rates per 100,000; incidence rate ratios, age-standardized incidence rates, prevalence and incidence rates of subtypes of STS, median, one-year and 5-year survival rates were examined.ResultsA total of 26,970 patients were identified. Between 1982 and 2009 STS incid...

We present here the case of a 77-year-old man who was incidentally found to have a huge right renal mass on computed tomography. Radical nephrectomy was performed. Pathological diagnosis was MFH arising from the renal capsule. We used Ion AmpliSeq Cancer Hotspot Panel version 2 primers to perform gene mutation screening. We detected 13 mutations in 11 hotspot oncogenes (CSF1R, FGFR3, KDR, APC, PDGFRA, TP53, FLT3, ERBB4, KIT, STK11, RET), but these were not matched to driver mutations.

Conclusions: The broad term of fibrous histiocytoma should be reserved for deep fibroblastic spindle cell tumors (e.g., those of the orbit) that display an aggressive behavior. More benign superficial spindle cell tumors of the dermis are now preferentially characterized as dermatofibromas. It is suggested that equally benign epibulbar tumors should no longer be designated as fibrous histiocytomas but rather as benign storiform fibrous tumors. Tumors completely composed of polygonal histiocytoid (epithelioid) cells that are CD34+ should be excluded from the benign storiform fibrous tumor category. Positive smooth muscle ...

Authors: Ziemer M, Jäger IM, Dippel E Abstract Atypical fibroxanthoma (AFX) or undifferentiated pleomorphic sarcoma (UPS) is a rare malignant neoplastic disease of the skin. At the beginning of the 1960s AFX was described as an independent entity and superficial variant of malignant fibrous histiocytoma (MFH). Since then, many controversies on the classification have arisen mainly because in many cases dedifferentiated neoplasms from other origins were falsely diagnosed as AFX. A relevant deep expansion, the invasion of nerves and vessels or the presence of tumor necrosis are described as being typical for UPS...

Abstract We are going to present a case of malignant fibrous histiocytoma in the right atrium, which is a very rare entity. The patient had a right atrial mass, which prolapsed through the tricuspid valve into the right ventricle, causing functional tricuspid valve stenosis. The tumor was completely resected and the patient had an uneventful postoperative period. Histopathological examination reported malignant fibrous histiocytoma. The patient presented to the emergency department five weeks after discharge with dyspnea and palpitation. Echocardiography and magnetic resonance imaging revealed recurrent right atrial tumor ...
