Malignant fibrous histiocytoma

Matthias Benndorf, Jakob Neubauer, Mathias Langer, Elmar Kotter
PURPOSE: In the diagnostic process of primary bone tumors, patient age, tumor localization and to a lesser extent sex affect the differential diagnosis. We therefore aim to develop a pretest probability calculator for primary malignant bone tumors based on population data taking these variables into account. METHODS: We access the SEER (Surveillance, Epidemiology and End Results Program of the National Cancer Institute, 2015 release) database and analyze data of all primary malignant bone tumors diagnosed between 1973 and 2012...

The paper reviews the 2016 WHO classification of prostate tumors, notes the alterations made, and describes approaches to the diagnosis of cancer types and grades. It also gives original photomicrographs from the authors' collection. The main alterations were as follows: - The types of prostate adenocarcinoma were added by pleomorphic giant-cell carcinoma; oncocytic (8290/3) and lymphoepithelial (8082/3) carcinomas were excluded. - Grade III prostatic intraepithelial neoplasia (PIN) was substituted for high grade PIN (8148/2)...

To date, there have been less than a 100 confirmed case reports of primary cardiac malignant fibrous histiocytomas, a rare form of sarcoma. In this report, we discuss the case of a 15-year-old girl who initially presented with a histiocytic cerebral sarcoma that was treated with aggressive resection and chemotherapy. Three years later, the same patient developed increasing shortness of breath and was found to have a high-grade pleomorphic undifferentiated cardiac sarcoma that likely represents the primary tumour from which the cerebral lesion metastasised...

Malignant fibrous histiocytoma (MFH) is a rare tumor that mostly involves adults aged 50 to 70. The most common anatomic location is the lower extremities. MFH of the retroperitoneum usually manifests late in its course and may be initially mistaken with other more common diagnosis. Here, the authors describe a 60-year-old man that was brought to the emergency department with a chief complaint of periumbilical abdominal pain. Our patient presented with symptoms consistent with a symptomatic aortic aneurysm, but a mass was encountered during surgery...

A 68-year-old man underwent serial F-FDG PET/CT scan follow-up for lung cancer. Then 5.5 years after the initial F-FDG PET/CT scan, the presumed benign bone tumor in the left clavicle showed markedly increased FDG uptake during follow-up; in contrast, the Tc-MDP bone scan paradoxically exhibited no apparent interval change since last bone scan 5.5 years earlier. He underwent a CT-guided biopsy, and the pathological diagnosis was benign fibrous histiocytoma. The result was consistent with the lack of progression in Tc-MDP bone scan, whereas the F-FDG PET/CT scan gave a false-positive impression of malignant transformation...

Angiomatoid fibrous histiocytoma (AFH), a rare soft tissue tumor of borderline malignancy, typically occurs in the subcutis of the accessible soft tissues, most often in children and young adults. Lymph node and/or distant metastasis is seen in <2% of patients with AFH. Exceptionally rare examples of AFH have been reported in visceral locations, including the lung. We report a genetically confirmed primary pulmonary AFH in a 70-year-old woman with mediastinal lymph node metastasis, representing to the best of our knowledge the first report of metastases from a visceral AFH...

This article focuses on various cancerous lesions that are found beyond organs in the intra-abdominal fat and can be visualized with ultrasonography. These lesions are divided into five groups. The first group includes primary benign tumors containing adipocytes, such as lipoma, lipoblastoma, hibernoma and other lesions with an adipose tissue component, such as myolipoma, angiomyolipoma, myelolipoma and teratoma. The second group comprises primary malignant adipocytecontaining tumors, including liposarcoma and immature teratoma...

A 12-year-old British Warmblood mare was examined by the referring veterinarian for evaluation of a cutaneous lesion on the dorsal thorax to the right of the midline. Cytologic examination of fine-needle aspirates from the mass was supportive of a giant cell tumor of soft parts (GCTSP). Laser surgical excision and postoperative methyl aminolevulinate (MAL) photodynamic therapy (PDT) were performed. Histologic examination of the mass confirmed the cytologic diagnosis. At 8 months from surgery, no evidence of recurrence has been observed...

Primary malignant fibrous histiocytoma (MFH) mainly occurs in the extremities, trunk and retroperitoneum. However, MFH of the mesentery is very rare, and locally recurred MFH is even rarer. MFH is severely malignant and invasive regionally. The neoplasm can spread quickly. This report is about a case of a recurred MFH in the mesentery, which locally recurred within 3 years from the original operation. The patient (female, age 71) underwent a resection of the small bowl and mesentery of the recurrent MFH with negative resection margins...

A 68-year-old woman was admitted to the Peking Union Medical College Hospital with a 6-week history of fever of undetermined origin. The computed tomography scan revealed a space-occupying lesion in the ascending colon and colonic endoscopy revealed a protrusive lesion in the initial segment of the ascending colon, occupying 3/5 of the lumen. Pathological examination of a biopsy specimen revealed malignant fibrous histiocytoma (MFH). The patient then underwent a laparotomy for right hemicolectomy and en bloc lymph node dissection...

BACKGROUND: The prevalence of tumors affecting the lacrimal drainage system is low, thus generating a risk of late diagnosis and treatment in clinical routine. However, these tumors can be potentially life-threatening, which emphasizes the relevance of early diagnosis and treatment. OBJECTIVE: This review focuses on the symptoms, incidence, management, and prognosis of the different tumor entities affecting the lacrimal drainage system. METHODS: The study provides a PubMed-based literature review and presents own clinical results...

Malignant fibrous histiocytoma (MFH) is a malignant mesenchymal tumor uncommonly seen in head and neck region and even rarer in maxillary sinus with less than thirty cases reported in literature. Microscopic diagnosis at this rare site may be challenging because of the spectrum of features, which frequently overlap with other benign and malignant tumors. We herein report a case of malignant fibrous histiocytoma of the maxillary sinus in a 40-year-old man who presented with epistaxis. The initial biopsy appeared benign whereas histopathology of wide surgical excision was consistent with MFH...

BACKGROUND: Angiomatoid fibrous histiocytoma (AFH) is an unusual soft tissue tumor (STT), characterized by recurrences, but rarely metastasis. Later, certain molecular signatures have been identified underlying this tumor, which at times, is either underdiagnosed as a benign vascular tumor, or over diagnosed as a high-grade pleomorphic sarcoma, including a malignant fibrous histiocytoma. MATERIALS AND METHODS: Over a 14-year-period, five diagnosed cases of AFH were analyzed...
