Reusing tissue of amputated or unsalvageable limbs to reconstruct soft tissue defects is one aspect of the "spare parts concept." Using a free fillet flap in such situations enables the successful formation of a proximal stump with the length needed to cover a large defect from forequarter amputation without risking additional donor-site morbidity. The use of free fillet flaps for reconstruction after forequarter and traumatic upper extremity amputations is illustrated here in a case report. A 41-year old patient required a forequarter amputation to resect a desmoid tumor, resulting in an extensive soft-tissue defect of the upper extremity...

INTRODUCTION: S100a4 is a calcium-binding protein belonging to the family of S100-proteins, highly expressed in different stromal cell types. S100A4 has been reported as a prognostic marker in colorectal cancer in association with tumour progression and metastasis. METHODS: In this study, we analysed the in vivo role of S100a4 in intestinal tumour initiation and progression using different transgenic and knockout mouse models. RESULTS: We found that genetic ablation or overexpression of S100a4 in both Apc- and Smad4-mutant mice do not affect tumour initiation in the intestinal tract...

Various histological variants of papillary thyroid carcinoma have been reported, some with clinical implications, some with peculiar, sometimes misleading morphologies. One of these rare and poorly characterized variants is papillary thyroid carcinoma with nodular fasciitis-like stroma, of which fewer than 30 cases have been documented, mostly as isolated reports. It is a dual tumor comprising a malignant epithelial proliferation that harbors typical features of conventional papillary thyroid carcinoma, admixed with a prominent mesenchymal proliferation resembling nodular fasciitis or fibromatosis...

Desmoid tumors (DT) are rare and nonmetastasizing fibroblastic neoplasms, characterized by local invasiveness. They occur sporadically or arise in the context of familial adenomatous polyposis (FAP; 5-10% of cases). Most cases develop sporadically in young adults, but some cases also occur in children. We report the case of an adolescent girl with FAP and DT, and we discuss the therapeutic strategies. An adolescent girl with FAP underwent surgery at the age of 14 years with total proctocolectomy. She had a neo-mutation in the APC gene at codon 1068, which is not usually associated with DT...

PURPOSE: Before the wait-and-see policy became the standard approach in abdominal wall desmoid tumors, surgery was performed on a systematic basis. Surgery remains indicated for progressing tumors but its extent is debatable. The abdominal wall is a common site of origin of sporadic desmoids, usually associated with a favorable prognosis. We analyzed the results of surgery at this specific site. METHODS: Data from 33 patients affected by sporadic desmoid tumors of the abdominal wall (31 primary, 2 recurrent) consecutively treated at our cancer center between January 2000 and September 2013 were retrospectively studied...

INTRODUCTION: Infantile myofibromatosis (IM) is a rare paediatric fibrous tumour also known as a desmoid tumour that occurs in around 1:150000 live births. It manifests as solitary or multicentric fibrous masses in the musculoaponeurotic soft tissues and can affect the visceral organs and bones. CASE DISCUSSION: We report a case of infantile myofibromatosis of the gluteus maximus muscle in an 18-day old neonate presenting atypically as a case of developmental dysplasia of the hip due to local involvement of the sciatic nerve...

Desmoid tumors, also known as aggressive fibromatosis, are locally infiltrating musculoaponeurotic neoplasms arising in connective tissues. Desmoid tumors may be associated with familial adenomatous polyposis (FAP), a genetic disorder that presents with hundreds to thousands of precancerous colorectal polyps. The authors report the case of an 18-month-old boy who underwent resection of a right temporal desmoid tumor (initially diagnosed as cranial fasciitis) and developed a bilateral frontoparietal calvarial desmoid tumor 2 years later...

BACKGROUND: Desmoid tumors, which are associated with familial adenomatous polyposis (FAP), tend to occur frequently in the abdominal wall and mesentery. Currently, there are no recognized treatments other than surgery, and frequent surgeries result in gastrointestinal obstructions and functional gastrointestinal disorders. CASE PRESENTATION: After surgery that was performed on a 39-year-old patient with FAP, we performed a second tumor excision which was the procedure used for frequently occurring mesenteric desmoid tumors...

BACKGROUND: Surgical resection of desmoid tumors has traditionally been the mainstay of therapy, but this is a potentially morbid approach with high rates of recurrence. Given increasing reports of active surveillance in this disease, we sought to evaluate our experience with conservative management hypothesizing this would be an effective strategy. MATERIALS AND METHODS: Using a prospectively maintained database of sarcoma patients from 2008 to 2015, we identified 47 patients with a diagnosis of desmoid tumor from all anatomic sites...

Desmoid-type fibromatosis of the breast (also referred to as desmoid tumor or aggressive fibromatosis) is exceedingly rare. Although it does not metastasize, desmoid-type fibromatosisis is frequently locally aggressive. Recurrence is common (up to 35%), even after presumed total excision of the primary tumor [1]. The breast is an unusual location for the development of this tumor, with relatively few cases reported in the literature. We report a case of desmoid-type fibromatosis in the breast in a 31-year-old female who presented with a four-month history of a palpable left breast mass...

Desmoid-type fibromatosis is a rare nonmetastasizing neoplasm with variable behavior. Recent discoveries into the biology of this disease hold promise for identifying prognostic and predictive features and novel therapeutic targets. Surgery has been the historical standard of care but carries considerable drawbacks in terms of high local recurrence rates and poor functional outcomes. Improved understanding of the natural history of desmoid-type fibromatosis has resulted in a paradigm shift toward nonoperative management...

Desmoid tumors are locally aggressive and non-metastatic neoplasms with a high rate of recurrence. Desmoid tumors of the pancreas are, however, very rare, and only a few cases have been reported in the literature. This paper reports an anecdotal case of a diffuse pancreatic desmoid tumor with the involvement of the pancreatic head, body, and-partially-tail. The patient underwent the Whipple procedure and subtotal pancreatectomy. Histopathological assessment showed that the tissues were partly positive for smooth muscle actin, but not for S100 or PanCK...

BACKGROUND: The efficacy of the classical treatment modalities surgery and radiotherapy in the treatment of aggressive fibromatosis is presently disputed and there is a shift towards a more conservative approach. The aim of the present study is to objectify tumor growth in patients with extra-abdominal or abdominal wall aggressive fibromatosis, while adhering to a "watchful waiting" policy. Other objectives are to investigate quality of life and to identify factors associated with tumor growth, in particular the relation with the presence of a CTNNB1-gene mutation in the tumor...

BACKGROUND: Nearly half of soft tissue sarcomas are nonrhabdomyosarcomas (NRSTSs). The low-grade (LG) form comprises a heterogenous group of diseases that rarely metastasize but are known for local recurrence. AIM OF THE STUDY: The aim of the study was to retrospectively evaluate pediatric LG-NRSTS with regard to demography, survival, and factors affecting outcome in Egyptian patients. PATIENTS AND METHODS: The study reviewed 66 NRSTS patients who presented to the Pediatric Oncology Department, National Cancer Institute, Cairo University, between January 2008 and December 2013...

Desmoid tumors are rare, comprising 3% of soft tissue tumors. Surgical resection has been the standard of care; however, this has begun to evolve into a movement of watchful waiting as observational studies have shown long-term stability of many tumors without treatment and even spontaneous regression in 5% to 10% of cases. When surgical therapy is used, wide local excision with microscopically negative margins is the goal of resection but should not be at the expense of organ or limb function. Recurrence rates after surgical resection are approximately 20%; a variety of multimodal therapies are useful in controlling disease...

INTRODUCTION: Desmoid tumors are rare proliferative and invasive benign lesions. They can be sporadic, but in most instances, desmoid tumors develop in the context of Gardner's syndrome with principal localization in the abdominal cavity and abdominal wall. CASE-REPORT: We report the case of a 24-year-old female presenting Gardner's syndrome with a symptomatic abdominal wall desmoid tumor. Lack of response to medical treatment led to surgical management consisting in a complete resection and parietal reconstruction with a biologic mesh...
