Pathological diagnosis of solitary fibrous tumor (SFT) in the pediatric population is challenging, as it occurs uncommonly in this age-group and resembles other spindle cell neoplasms. SFT contains a NAB2-STAT6 fusion gene, which can be reliably detected using STAT6 immunohistochemistry. Positive staining is highly sensitive and specific. We sought to investigate the utility of STAT6 immunohistochemistry, to show how commonly SFT was historically recognized at 3 academic pediatric institutions, to reclassify them when appropriate, and to demonstrate features of major mimics of SFT...

PURPOSE: To evaluate the clinical significance and rarity of tamoxifen retinopathy after a long-term tamoxifen treatment for an inoperable desmoid tumor. METHODS: Case report. RESULTS: Tamoxifen retinopathy is a condition rarely observed in clinical practice. Although tamoxifen is typically a treatment for breast cancer patients, we present a 68-year-old woman taking tamoxifen for an inoperable desmoid tumor, an equally rare condition. She presented with bilaterally deteriorating vision over the course of a year...

In this review, we highlight the complexities of the natural history, biology, and clinical management of three intermediate connective tissue tumors: desmoid tumor (DT) or aggressive fibromatosis, tenosynovial giant cell tumor (TGCT) or diffuse-type pigmented villonodular synovitis (dtPVNS), and giant cell tumor of bone (GCTB). Intermediate histologies include tumors of both soft tissue and bone origin and are locally aggressive and rarely metastatic. Some common aspects to these tumors are that they can be locally infiltrative and/or impinge on critical organs, which leads to disfigurement, pain, loss of function and mobility, neurovascular compromise, and occasionally life-threatening consequences, such as mesenteric, bowel, ureteral, and/or bladder obstruction...

A primary desmoid tumor arising from the chest wall is extremely rare. We report the case of a 57-year-old man presenting with a desmoid tumor arising from his chest wall. Chest radiograph at a regular medical checkup indicated an abnormal shadow. By computed tomography-guided biopsy, he was diagnosed as having a desmoid tumor. He underwent right-sided chest wall resection and reconstruction. Desmoid tumor is histopathologically benign tumor, however, they tend to show high rates of local recurrence after surgery...

An unusual case of a jejunal mesenteric pseudocyst treated by laparoscopic resection is reported. A 44-year-old woman was admitted to our hospital with intermittent upper abdominal pain and diarrhea. Physical examination revealed slight periumbilical tenderness, and no masses were palpable. Contrast-enhanced computed tomography showed a 4-cm-sized nonenhancing high-density mass with a heterogeneous pattern on a proximal small bowel loop. Based on these findings, a gastrointestinal stromal tumor accompanied by hemorrhagic and cystic change, a mesenteric hematoma, or a desmoid tumor was diagnosed...

Desmoid type fibromatosis (DTF) is a rare, locally invasive, non-metastasizing soft tissue tumor. We report an interesting case of DTF involving the pancreatic head of a 54-year-old woman. She presented with intermittent dysphagia and significant weight loss within a 3-mo period. Laboratory findings showed mild elevation of transaminases, significant elevation of alkaline phosphatase and direct hyperbilirubinemia, indicating obstructive jaundice. Computerized tomography of the abdomen revealed a mass in the head of the pancreas, dilated common bile duct, and dilated pancreatic duct...

BACKGROUND: Intra-abdominal desmoid tumors are usually slow growing and solitary, but multifocal desmoid tumors develop on rare occasions. Diagnosing desmoid tumors before histological examination of a surgical biopsy is often difficult. In particular, if a patient has a prior history of malignancy, it may be difficult to differentiate between these lesions and disease recurrence or metastasis. CASE PRESENTATION: We present a rare case of multiple rapidly growing intra-abdominal desmoid tumors after surgical trauma, without familial adenomatous polyposis...

PURPOSE: Wnt signaling is implicated in tumor cell de-differentiation and cancer stem cell function. Ipafricept (OMP-54F28) is a first-in-class recombinant fusion protein with the extracellular part of human Frizzled 8 receptor fused to a human IgG1 Fc fragment that binds Wnt ligands. This trial evaluated ipafricept in patients with solid tumors. EXPERIMENTAL DESIGN: A 3+3 design was used; ipafricept was given intravenously every 3 weeks. Objectives were determination of dose-limiting toxicities (DLTs), recommended phase 2 dose (RP2D), safety, pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD), and preliminary efficacy...

REVIEW
Augusto Lauro, Ignazio R Marino, Kishore R Iyer
Pre-emptive transplantation is a well-established practice for certain types of end-organ failure such as in the use of kidney transplantation. For irreversible intestinal failure, total parenteral nutrition (TPN) remains the gold standard, due to the suboptimal long-term results of intestinal transplantation. As such, the only role for pre-emptive transplantation, if at all, will be for patients identified to be at high risk of complications and mortality while on definitive long-term TPN. In these patients, the timing of early listing and transplantation could become life-saving, taking into account that mortality on the waiting list is still the highest for intestinal candidates...

We report the case of a 16-year old patient presenting with giant, multinodular, mesenchymal tumor of the abdominal wall occupying the left abdominal region and measuring 25 cm on the vertical axis, 20 cm on the transverse axis, mobile when compared with the deep structures and gradually increasing in volume over childhood and neglected. After small biopsy, which showed desmoid tumor, the patient underwent complete surgical resection of the tumor with immediate reconstruction by free muscolo skin flap of the latissimus dorsi attached to the large blood vessels of the inguinal fold (left iliac artery and left external iliac vein), connected by termino lateral anastomosis...

Objectives: Accurate diagnosis of malignant peripheral nerve sheath tumor (MPNST) is often challenging on fine-needle aspiration (FNA) or core needle biopsy. Recurrent mutations in EED and SUZ12, which encode subunits of polycomb repressive complex 2 (PRC2), have been identified in 70% to 92% of MPNSTs; PRC2 inactivation leads to loss of trimethylation of lysine 27 of histone H3 (H3K27me3). We evaluated the utility of H3K27me3 immunohistochemistry for distinguishing MPNST from its cytomorphologic mimics...

Plexiform fibromyxoma is a very rare mesenchymal tumor of the stomach, found almost exclusively in the antrum/pylorus region. The most common presenting symptoms are anemia, hematemesis, nausea and unintentional weight loss, without sex or age predilection. We describe here two cases of plexiform fibromyxoma, involving a 16-year-old female and a 34-year-old male. Both patients underwent complete resection (R0) by distal gastrectomy and retrocolic gastrojejunostomy (according to Billroth 2); for both, the postoperative course was uneventful...

Aggressive fibromatosis (AF) or desmoid tumors is an aggressive fibroblastic proliferation which is locally invasive but can not metastasize. The treatment of AF is challenging. Surgery was the main treatment modality for AF in the past, other strategies including radiotherapy, systemic therapies and wait-and-see policy. The use of non-steroidal anti-inflammatory drugs (NSAIDs) and targeted therapies has demonstrated good results. In the case report, a 39-year-old man presented with progressive chest wall pain...

BACKGROUND: Immunohistochemical staining with conventional anti-β-catenin antibody has been applied as a diagnostic tool for desmoid-type fibromatosis (DF). This study aimed to evaluate the diagnostic and prognostic value of immunohistochemical staining with anti-non-phospho β-catenin antibody, which might more accurately reflect the aggressiveness of DF, in comparison to the conventional anti-β-catenin antibody. METHODS: Between 2003 and 2015, 40 patients with extra-peritoneal sporadic DF were prospectively treated with meloxicam or celecoxib, a COX-2 inhibitor, therapy...
