OBJECTIVE: Peripheral venous reconstruction surgery may be necessary for appropriate oncologic resection; however, the operative approach and surgical outcomes are not well described. We report our experience with these complex reconstructions to identify best practice. METHODS: We retrospectively reviewed all adult patients who underwent peripheral vein reconstruction for tumor resection at Mayo Clinic, Rochester (2000-2015). Patients were classified into three subgroups by the location: iliac (IL), lower extremity (LE), and upper extremity (UE)...

INTRODUCTION: Tumors localized in the proximal tibial meta-diaphysis often lead to osteoarticular resections. MATERIALS AND METHODS: In this study, we retrospectively reviewed four patients who underwent intercalary tumor resection and reconstruction using an ultra-short stem in the proximal tibial epiphysis, a procedure that to our knowledge has not been reported in literature so far. RESULTS: At the time of operation, the mean patient age was 26...

We present a very rare case of malignant transformation of a benign mature cystic teratoma. The pathology report revealed malignant transformation of both the epithelial and sarcomatous elements of a benign dermoid cyst. To the best of our knowledge, this appears to be the third case of a malignant fibrous histiocytoma and a squamous cell carcinoma developing from a mature cystic teratoma. Malignant transformation of a dermoid cyst is usually diagnosed postmenopausally, but our patient was premenopausal. The etiology and prognosis of malignant transformation of this benign condition remain unknown...

INTRODUCTION: It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare, benign tumors that originate from the peritoneal mesothelium and are more common in women...

Primary malignant fibrous histiocytoma of the thyroid is an uncommon malignancy of the thyroid. Because it is rare, fewer than 20 cases have been reported in the literature, and the sonographic features of only 2 cases have been reported between the 1980s and 2014. Here we report 2 cases of primary malignant fibrous histiocytoma of the thyroid with an emphasis on the sonographic findings, and we review the published literature.

Malignant fibrous histiocytoma is a sarcoma with rare occurrence in the oral and maxillofacial region; surgery is the most reliable treatment. Inadequate resection of the sarcoma on the oral and maxillofacial region is associated with a high incidence of local recurrence and a poor prognosis. Only few patients of malignant fibrous histiocytoma of the malar region have been previously reported in the literature. The authors report a new patient of malignant fibrous histiocytoma on the right malar region that treated a complete tumor surgical excision without lymph node dissection...

BACKGROUND: The cytostatic effects of the polyphenol curcumin and Viscum album extract (VAE) were assessed in soft-tissue sarcoma (STS) cells. METHODS: Eight human STS cell lines were used: fibrosarcoma (HT1080), liposarcoma (SW872, T778, MLS-402), synovial sarcoma (SW982, SYO1, 1273), and malignant fibrous histiocytoma (U2197). Primary human fibroblasts served as control cells. Cell proliferation, viability, and cell index (CI) were analyzed by BrdU assay, MTT assay, and real-time cell analysis (RTCA)...

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumour with intermediate malignant potential. We report the case of a patient with local recurrence of AFH in two locations and lymph node metastases 18 months after primary surgical excision. The patient was treated with six cycles of ifosfamide and doxorubicin chemotherapy and a further three courses of ifosfamide monotherapy. Reassessment imaging showed a good response to chemotherapy with reduction in size of the two tumours of local recurrence and the lymph node metastases...

Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, usually arises in the extremities and retroperitoneum. Primary laryngeal undifferentiated pleomorphic sarcoma is very rare, with only 63 cases having been reported in the literature as of 2015. The disease has a poor prognosis because of problems with local recurrence and metastasis. Wide resection has been recommended as a treatment modality in previous reports. We report a case of undifferentiated pleomorphic sarcoma of the vocal fold in a 64-year-old man presenting with rapid growth...

Malignant fibrous histiocytoma amplified sequence 1 (MFHAS1) is a predicted oncoprotein that demonstrates tumorigenic activity in vivo; however, the mechanisms involved are unknown. Macrophages are divided into the pro-inflammatory M1 and anti-inflammatory/protumoral M2 subtypes. Tumor cells can induce M2 polarization of tumor-associated macrophages (TAMs) to promote metastasis; but the underlying pathways require to be elucidated. In this study, we detected a positive association between MFHAS1 expression in TAMs and human colorectal cancer (CRC) TNM stage...

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...
