Imaging revealed a tumour eroding through the inner and outer skull tables, closely associated with major underlying dural sinuses. She underwent complete macroscopic resection of the tumour and reconstruction of a titanium mesh cranioplasty. Histology favoured a benign process with a diagnosis of BFH of the calvarium given. At 1 year follow-up, the patient is asymptomatic and has not developed recurrence of the tumour.展开更多

There have been no reports to date of hepatic MFH associated with liver cirrhosis. The presence of liver cirrhosis is considered an adjunctive feature favoring sarcomatoid hepatocellular carcinoma (HCC) in the diagnosis of spindle cell tumors in liver. We describe here a 59-year-old man with liver cirrhosis due to hepatitis B virus infection 20 years ago. On abdominal computed tomography scanning, two distinct hepatic masses were identified in the background of cirrhosis, which had different radiological features from conventional HCC. He underwent segmentectomy for removal of the tumors. The pathological examination of surgically resected specimen revealed the large malignant spindle cell tumor and small conventional HCC. Additional tissue sampling and immunohistochemical stainings demonstrated that the spindle cell tumor was consistent with MFH. On the post-operative follow-up for 21 mo, a round mass showing similar radiological findings for the previous MFH was appeared on the surface of resection margin, suggesting the recurrence. Despite its rarity, hepatic MFH should be considered during differential diagnosis, even in cirrhotic patients, and extensive tissue sampling and immunohistochemical analyses are necessary in the diagnosis of hepatic spindle cell tumors.展开更多

Materials and Methods: The primary sites were:cranio-facial 16, trunk and extremity 12 and abdominal 17 (13 retroperitoneal). As seen on CT scans, the lesion is clear-margined and even when small, but, when large (42/50,>5 cm), it is uneven in consistency and apt to invade the nearby organs (75.8%). The CT Findings of untreated and recurrent MFH are similar. Results:Enhanced CT scans may provide useful information such as medium to hyper-attenuation (78.8%), necrosis (60.6%)or involvement of para-nasal sinuses as expanding deformity (8/9 cases). Conclusions: CT scan is important to delineate the extent of MFH Iesions of which the diagnosis is best ascertained by combining CT scan and histopathology. Enhanced CT scans can reveal much useful information.展开更多

AFH has a higher recurrence rate than FH. The diagnosis of AFH is often problematic due to its overlapping morphological features with other skin tumors. The diagnosis of AFH depends on histological features and immunohistochemistry. The aim of this study is to understand the clinical and histopathological diagnostic criteria for AFH.展开更多

We herein present an extremely rare case of pancreatic metastases of malignant fibrous histiocytoma (MFH) undergoing pancreaticoduodenectomy with tumor-free survival within postoperative 35-month follow-up. Pancreatic resection for metastatic MFH to the pancreas should be considered in selected patients. Long-term survival or good palliation may be achieved.展开更多

Four days before admission, he wasepisode of dyspnoea, could not prostrate with non- productive cough when he was offered with a gastroscopy examination in a local hospital due to anepithymia. The patient had no history of medication or allergies. However, he had smoked for more than thirty years-sixty cigarettes per day. Chest distress without haemoptysis, pink frothy sputum, apsychia, amaurosis, and fever was developed. The symptoms worsened gradually. On examination at the Department of Emergency, Shenzhen People＇s Hospital, dyspnoea with jugular vein distension and oedema in his head, neck and thoracic region were discovered. The breathing sounds on both lower lungs were low. His heart rate was 100 beats/min without arrhythmia or murmur. His abdomen was soft without rebound tenderness. His liver and spleen were not palpable. Pitting oedema occurred in both low limbs. Furosemide was given, but the symptoms were not relieved.展开更多

We describe the detailed clinical features of 8 cases and fully review the literature to evaluate several prognostic factors. Methods: Eight patients with pathologically confirmed primary intracranial MFH were retrospectively reviewed. We searched Pub Med for relevant articles with the term "intracranial malignant fibrous histiocytoma". Results: Of the 8 patients, 4 were men and 4 were women. Three patients had received previous radiotherapy. The age of the patients ranged from 19 to 69 years, with a median age of 48 years. Most tumors could be totally resected; and only 1 tumor was subtotally resected. Six patients received postoperative radiotherapy and 3 patients received postoperative chemotherapy. Most patients died within the first year after surgery; and only 1 patient was still alive on the date of the last follow-up. We reviewed the literature and included a total of 46 patients in the Kaplan-Meier survival analysis. Young patients(less than 30 years old) seemed to have a better prognosis and survival rate than older patients(more than 30 years old)(log-rank test, P = 0.008).However, sex(P = 0.675), extent of resection(P = 0.934), postoperative radiotherapy(P = 0.592), and postoperative chemotherapy(P = 0.424) did not affect patient prognosis.Conclusions: The prognosis of MFH is usually poor, and most patients die within the first year after surgery. Younger MFH patients(less than 30 years old) seem to have a better prognosis and improved survival compared to older patients.展开更多
