High pressure paint injection injury is an uncommon but well-described injury. The histologic features of long-term paint injection injury with retained material are less recognized. A 46 year old male presented clinically as "recurrent giant cell tumor of tendon sheath". The right index finger demonstrated fusiform enlargement by a pigmented mass with diffuse infiltration into the soft tissue of the hand. Histologically the tumor showed multiple giant cells in a fibrotic stroma extending into the dermis. There were multiple types of foreign material including diffuse brown black pigment, weakly optically polarizing foreign material and white inclusions with a "train track" appearance...

Non-gastrointestinal stromal tumor (GIST) soft tissue sarcomas (STSs) are a heterogeneous group of neoplasms whose classification and management continues to evolve with better understanding of their biologic behavior. The 2013 World Health Organization (WHO) has revised their classification based on new immunohistochemical and cytogenetic data. In this article, we will provide a brief overview of the revised WHO classification of soft tissue tumors, discuss in detail the radiology and management of the two most common adult non-GIST STS, namely liposarcoma and leiomyosarcoma, and review some of the emerging histology-driven targeted therapies in non-GIST STS, focusing on the role of the radiologist...

Rhabdomyomas are rare striated muscle-type tumors arising in the heart or in soft tissues. Using a monoclonal antibody specific for the cardiac isoform of α-actin (α-cardiac actin, α-CAA), differential expression patterns in striated muscle tissues were reported previously. The purpose of the present study was to determine whether the α-actin isoform specificity is maintained in rhabdomyomas according to their origin, comparing extracardiac to cardiac rhabdomyomas. We immunohistochemically investigated adult extracardiac (pharyngeal) rhabdomyomas (n = 4) and cardiac rhabdomyomas (n = 7) employing isoform-specific monoclonal antibodies...

Background Hemangiomas are sometimes difficult to diagnose with current techniques. Sluggish speed signs (SSS) are a phenomenon that: (i) cannot be depicted as Doppler flow on Doppler ultrasound; (ii) can be observed as fluid movements on Doppler ultrasound; and (iii) cannot be depicted as waveforms on pulse Doppler mode. We hypothesized that SSS could be diagnostic indicators for hemangiomas. Purpose To evaluate whether ultrasound findings, in particular those relating to SSS, are a reliable tool for detecting hemangiomas compared to magnetic resonance imaging (MRI) and the gold standard for hemangioma diagnosis: pathological examination by biopsy or after surgical resection...

PURPOSE: Local recurrence is a common and morbid event in patients with unresectable pancreatic adenocarcinoma. A more conformal and targeted radiation dose to the macroscopic tumor in nonmetastatic pancreatic cancer is likely to reduce acute toxicity and improve local control. Optimal soft tissue contrast is required to facilitate delineation of a target and creation of a planning target volume with margin reduction and motion management. Magnetic resonance imaging (MRI) offers considerable advantages in optimizing soft tissue delineation and is an ideal modality for imaging and delineating a gross tumor volume (GTV) within the pancreas, particularly as it relates to conformal radiation planning...

BACKGROUND: Musculoskeletal tumors involving the deltoid muscle and necessitating its complete resection are rare. The function after complete deltoid resection is reported to be limited, and several authors consider muscle transfer to improve shoulder motion. However, it still remains unclear whether such transfer adds function. To the best of our knowledge, all reports on complete deltoid resection refer to adult patients, and it is unknown what function results after deltoid resection in childhood...

BACKGROUND: Limb-sparing surgery for sarcomas has become possible in most cases. However, the impact of the procedure on the functional outcome has only been investigated in a few studies. The aim of this study has been to identify tumor- and patient-related factors associated with reduced functional outcome and quality of life after limb-sparing surgery in soft tissue sarcoma patients. MATERIAL AND METHODS: In total, 128 patients (mean age = 58, female/male = 54/74) who were treated with limb-sparing surgery without bone resection for soft tissue sarcomas in Denmark during the period 1 January 2009 to 31 December 2011 were included...

OBJECTIVE: The far upstream element (FUSE)-binding protein 1 (FUBP1) is a transactivator of human c-myc proto-oncogene transcription, with important roles in carcinogenesis. However, the expression pattern and potential biological function of FUBP1 in clear cell renal cell carcinoma (ccRCC) is yet to be established. METHODS: FUBP1 expression was detected in ccRCC tissues and cell lines by real-time RT-PCR, Western blot analysis, and immunohistochemistry. The correlations of FUBP1 mRNA expression levels with clinicopathological factors were evaluated...

Ultrasound-based elastography techniques including quasi-static strain elastography (SE), acoustic radiation force Impulse (ARFI) imaging, point shear wave elastography (pSWE) and supersonic shear imaging (SSI) have been used to differentiate breast tumors. The objective of this study is to extend a previously published virtual simulation platform of SE toward acoustic radiation force-based breast elastography. The proposed platform inherited four key components from the previously published virtual SE platform: an ultrasound simulator (Field II), a mesh generator (Tetgen), a finite element (FE) solver (FEBio) and a visualization and data processing package (VTK)...

Granular cell tumor (GrCT) is a benign nerve sheath tumor. Atypical and malignant variants of GrCT are rare but have been well described. We report a case of multifocal symmetric atypical GrCT in the bilateral hand/wrists of a 15 year old African American female. The initial clinical impression for both masses were favored to be ganglion cysts. Ultrasound findings of both masses revealed hypoechoic soft tissue lesions with some internal echogenicity favoring complex cysts. On excision, both masses were histologically circumscribed, lobulated, and attached to tendon...

BACKGROUND: Current National Comprehensive Cancer Network guidelines for the treatment of retroperitoneal sarcomas (RPS) endorse surgical resection, but the role of radiotherapy (RT) is less clear. We investigate the utilization and benefits of intraoperative RT (IORT) in the treatment of RPS. METHODS: We queried the Surveillance, Epidemiology and End Results (SEER) database (1988-2013) for the utilization of IORT and perioperative external beam RT (EBRT) in patients who underwent surgical resection of RPS...

A 70-year-old man with suspected prostate cancer was referred for Ga-PSMA-HBED-CC PET/CT (short PSMA PET/CT) for staging of tumor extent. Apart from vivid tracer uptake in the prostate gland and osseous metastasis, PSMA PET/CT revealed a large soft tissue mass with calcifications in the left upper abdomen showing intense tracer uptake. Histologic examination revealed the mass to be a gastrointestinal stromal tumor.

Neurofibromatosis type 1 (NF1) is a common tumor-predisposition disorder due to germline mutations in the tumor suppressor gene NF1. A virtually pathognomonic finding of NF1 is the plexiform neurofibroma (PN), a benign, likely congenital tumor that arises from bi-allelic inactivation of NF1. PN can undergo transformation to a malignant peripheral nerve sheath tumor, an aggressive soft-tissue sarcoma. To better understand the non-NF1 genetic contributions to PN pathogenesis, we performed whole-exome sequencing, RNASeq profiling and genome-wide copy-number determination for 23 low-passage Schwann cell cultures established from surgical PN material with matching germline DNA...

PURPOSE: In early-stage classical Hodgkin lymphoma, fluorodeoxyglucose positron emission tomography (PET)-computed tomography (CT) scans are performed routinely after chemotherapy, and the 5-point Deauville score is used to report the disease response. We hypothesized that other PET-CT parameters, considered in combination with Deauville score, would improve risk stratification. METHODS AND MATERIALS: Patients treated for stage I to II Hodgkin lymphoma from 2003 to 2013, who were aged ≥18 years and had analyzable PET-CT scans performed before and after chemotherapy, were eligible...

PURPOSE: The advent of microvascular free tissue transfer has provided the reconstructive surgeon with an enormous array of treatment options for reconstruction of large head and neck defects. However, when indicated by defect size, the need for more than 1 flap not only increases surgical complexity but also patient morbidity. The combination of the anterolateral thigh (ALT) flap and the tensor fascia latae (TFL) flap can be used to reconstruct such complex head and neck defects, thereby minimizing any additional morbidity that would be imposed by an additional flap harvest site...
