To determine the frequency of c-Kit staining in desmoids and optimize an assay for clinical use, we stained 19 desmoids from various sites at various dilutions with 2 commonly used rabbit polyclonal, anti-c-Kit antibodies (A4502, DAKO, Carpinteria, CA; C-19, Santa Cruz Biotechnology, Santa Cruz, CA), with and without heat-induced epitope retrieval (HIER) in citrate buffer. Approdpriate external...

PATIENT Male, 69. FINAL DIAGNOSIS Mesenteric desmoid tumor. SYMPTOMS -. MEDICATION -. CLINICAL PROCEDURE -. OBJECTIVE Rare disease. BACKGROUND Intra-abdominal fibromatosis is a benign rare tumor of fibrous origin with a significant potential for local invasion and no ability to metastasize, but it can recur. The etiology of desmoid tumors is unknown. It is often associated with cond...

introduction: due to the whole network of polyposis registers worldwide and early prophylactic treatment, survival of familial adenomatosis (fap) patients is improved. extracolonic manifestations are remarkable feature of fap. two extracolonic manifestations (duodenal adenomatosis, leading duodenal cancer and desmoid tumours) play a very important role in the reasons of death in polyposis popul...

INTRODUCTION Primary chest wall sarcomas are rare mesenchymal tumors and their mainstay of therapy is wide surgical resection. We report our single-institution, multidisciplinary experience with full-thickness resection for primary chest wall sarcomas. METHODS A retrospective review of our prospectively maintained databases revealed that 51 patients were referred for primary chest wall sarcom...

We used 2-deoxy-2-[(18)F] fluoro-D-glucose (FDG) positron emission tomography (PET) to evaluate patients with desmoid tumors undergoing therapy with imatinib. The study included 22 patients with progressive disease (PD) of a biopsy proven desmoid tumor treated orally with imatinib 800 mg daily. Patients were examined using PET prior to onset of therapy and during treatment. Restaging was perfor...

PURPOSE The aim of this study was to evaluate the feasibility, safety and therapeutic effects of ultrasound (US)-guided high intensity focused US (HIFU) ablation in the treatment of extra-abdominal desmoid tumours. MATERIALS AND METHODS From May 2006 to May 2010, ten consecutive patients with pathologically proven extra-abdominal desmoid tumours were treated by US-guided HIFU ablation. Eight ...

BACKGROUND Intra-thoracic desmoid tumours with mediastinal invasion are very rare. Although rare they have to be taken into account in the differential diagnosis of a thoracic mass and therapeutic options have to be weighted since surgical treatment may require wide excision. CASE PRESENTATION A 48-year-old male diabetic, dyslipidaemic, former heavy smoker with psychiatric illness was operate...

BACKGROUND Antecedent trauma has been implicated in the causation of soft tissue tumors. Several criteria have been established to define a cause-and-effect relationship. We postulate possible mechanisms in the genesis of soft tissue tumors following antecedent traumatic injury. CASE PRESENTATION We present a 27-year-old woman with a paraspinal desmoid tumor, diagnosed 3-years following a mot...

BACKGROUND Primary intra-thoracic desmoids are exceedingly rare borderline tumors, with 34 reported cases in the English-language literature. The characteristic localized infiltrative growth and the high rate of recurrence can result in life-threatening conditions. Radical surgical resection is considered to be the primary treatment. Achieving negative surgical margins is a challenge. Cases wit...

Desmoid tumors are benign, slow-growing mesenchymal tumors. Aggressiveness is local with no potential for metastasis or dedifferentiation. The treatment is challenging, particularly in the case of huge intra-abdominal locations. We, herein, report on a 21-year-old patient with a giant intra-abdominal desmoid tumor occupying substantially the entire abdominal cavity. After failure of a first-lin...
