Abstract
Desmoid fibromatosis is a locally aggressive tumor with an unpredictable clinical course. Surgery was once the mainstay of treatment, but the treatment protocol has been constantly evolving and currently active surveillance is the front-line approach. There have been significant insights into the molecular biology with the addition of mutational analysis of CTNNB1 adding to prognostic information. We present a review of the literature with current practice guidelines, also including novel therapeutic targets and ongoing clinical trials, to unravel the next step in the management of sporadic desmoid fibromatosis.

Abstract
CONTEXT - Pleural pathology has been dominated by discussions relating to the diagnosis, prognosis, etiology, and management of malignant mesothelioma. However, there exists a diverse group of other neoplasms that involve the pleura; the most common by far is metastatic carcinoma, usually of pulmonary origin. Other metastatic tumors of varied histogenesis do occur but are less common. Primary pleural neoplasms other than diffuse malignant mesothelioma are either uncommon or rare and have received less attention. OBJECTIVE - To provide a review of those diverse tumors that can involve the pleura other than mesothelioma in order to facilitate their accurate diagnosis. DATA SOURCES - Review of relevant literature published via PubMed and other search engines. CONCLUSIONS - A wide variety of tumors can involve the pleura. In most cases, the approach of considering the morphologic features with appropriate immunohistochemistry, in the correct clinical context, allows for a confident diagnosis. For a number of those soft tissue tumors that are well recognized in the pleura, such as solitary fibrous tumor, desmoid-type fibromatosis, synovial sarcoma, and epithelioid hemangioendothelioma, novel markers now exist based on an understanding of the individual tumors' molecular characteristics. Primary pleural lymphomas are rare with poor prognosis. They represent localized specific diffuse large B-cell lymphomas, with either post-germinal center B-cell or plasma cell lineage, arising in the context of either immunodeficiency or immune sequestration and with viral infection.

Abstract
BACKGROUND Desmoid-type fibromatosis (DTF) is a lesion characterized by clonal proliferation of myofibroblasts, which exhibits an infiltrative growth pattern. It is necessary for them to be distinguished from other fibroblastic and myofibroblastic lesions as well as spindle cell tumors. Altered Wnt signaling can act as a defining characteristic of DTF, with nuclear β-catenin serving as a diagnostic marker for. Transcription factor E3 (TFE3) has been linked to Wnt pathway activation and regulation, and may add value to the diagnosis of DTF. The present study, therefore, sought to assess whether TFE3 is a specific diagnostic marker for DTF. METHODS Nuclear TFE3 and β-catenin staining was performed on a wide range of tumor types such as DTF (n = 46), nodular fasciitis (n = 14), neurofibroma (n = 5), dermatofibrosarcoma protuberans (n = 5), gastrointestinal stromal tumor (n = 10), sclerosing epithelioid fibrosarcoma (n = 2), synovial sarcoma (n = 5), leiomyoma (n = 3) and cutaneous scar tissue (n = 4) using an immunohistochemical approach. In addition, the clinicopathological features and localization of these tumors were summarized. FISH assay was carried out to examine Xp11.2 translocations/TFE3 gene fusions. Statistical difference between immunohistochemical expression of TFE3 and β-catenin was analyzed. RESULTS The expression of nuclear TFE3 protein was found in 43 (93.5%) DTF tissue samples, ranging from moderate to intense expression levels. The distribution rates of TFE3 positivity in nodular fasciitis, gastrointestinal stromal tumor, leiomyoma and scar tissue samples were 42.9, 40, 25 and 33%, respectively. All studied samples of neurofibroma, synovial sarcoma, sclerosing epithelioid fibrosarcoma and dermatofibrosarcoma protuberans were negative for TFE3. CONCLUSIONS This study reveal that TFE3 has a potential to serve as a diagnostic marker capable of assisting in the differential diagnosis of DTF and other spindle cell lesions.

Abstract
A wait and see approach for desmoid tumors (DT) has become part of the routine treatment strategy. However, predictive factors to select the risk of progressive disease are still lacking. A translational project was run in order to identify genomic signatures in patients enrolled within an Italian prospective observational study. Among 12 DT patients (10 CTNNB1-mutated and 2 wild type) enrolled from our institution only two patients (17%) showed a progressive disease. Tumor biopsies were collected for whole exome sequencing. Overall, DT exhibited low somatic sequence mutation rate and no additional recurrent mutation was found. In the two wild type (WT) cases, two novel alterations were detected: a complex deletion of APC and a pathogenic mutation of LAMTOR2. Focusing on WT DT subtype, deep sequencing of CTNNB1, APC and LAMTOR2 was conducted on a retrospective series of 11 WT DT using a targeted approach. No other mutation of LAMTOR2 was detected, while APC was mutated in two cases. Low-frequency (mean reads of 16%) CTNNB1 mutations were discovered in five samples (45%) and two novel intra-genic deletions in CTNNB1 were detected in two cases. Both deletions and low frequency mutations of CTNNB1 were highly expressed. In conclusion, a minority of DT is WT for either CTNNB1, APC or any other gene involved in the WNT pathway. In this subgroup novel and hard to be detected molecular alterations in APC and CTNNB1 were discovered, contributing to explain a portion of the allegedly WT DT cases.

Abstract
Aggressive fibromatosis, also known as desmoid-type fibromatosis (DTF) or desmoid tumor, is an uncommon locally invasive tumor. Because of its low incidence and variable behavior, DTF is often first seen by physicians who are not familiar with it, and recent advances in understanding this disease have led to changes in treatment approaches. The Wnt (β-catenin) pathway appears to play a key role in DTF pathogenesis, and recent studies of DTF biology suggest a possible model of DTF pathogenesis. Histologically, DTF shows a poorly circumscribed proliferation of myofibroblast-like cells with variable collagen deposition, similar to the proliferative phase of wound healing, and DTF has been associated with trauma and pregnancy. Desmoid-type fibromatosis may be a useful model of the tumor stroma in carcinomas as well as other fibrosing diseases such as progressive pulmonary fibrosis. The clinical course of DTF can vary greatly among patients, complicating the determination of the optimal treatment approach. Treatment options include surgery, nonsteroidal anti-inflammatory drugs with or without hormonal manipulation, chemotherapy, radiation therapy, and other forms of local therapy. Many treatments have been used, but these are not without toxicities. Because of the variable nature of the disease and the potential morbidity of treatment, some cases of DTF may do better without treatment; simple observation is often the best initial treatment. This review used a PubMed search from January 1, 1980, through October 31, 2016, using the terms fibromatosis and desmoid and discusses DTF disease characteristics, pathophysiology, and treatment options as well as examines several cases illustrating key points in the biology and treatment of this heterogeneous disease.

Abstract
Extra abdominal desmoid fibromatosis is a complex condition with many recognised treatments including active observation, hormonal therapy, chemotherapy, radiotherapy and surgical resection. There is large variation in the natural history of individual desmoid tumours, with some cases progressing aggressively and others regressing spontaneously when observed alone. This combined with an absence of accurate clinical predictors of a desmoid tumour's behaviour has led to difficulties in identifying which patients would benefit most from aggressive treatment, and which could be adequately managed with a policy of active observation alone. This review explores the aetiology and common presentation of extra-abdominal desmoid fibromatosis including the condition's histopathological, clinical and radiological characteristics. The current evidence for potential predictors of desmoid tumour behaviour is also reviewed, along with the indications and evidence for the multitude of treatments available. We also summarise the published guidelines that are currently available for oncologists and surgeons managing extra-abdominal desmoid fibromatosis, and highlight some of the unanswered questions that need to be addressed to optimise the management of this condition.

Abstract
AIMS The diagnosis of osteosarcoma, although important for eligibility in clinical trials and proper therapy, may be challenging when no bone or osteoid matrix is identified on biopsy. Therefore, other adjunct tests have been sought to help confirm the diagnosis. Special AT-rich sequence-binding protein 2 (SATB2) has been shown as a reliable marker of osteoblastic differentiation. The aim of this study was to examine SATB2 expression in osteosarcomas and other primary bone sarcomas, in order to evaluate its diagnostic utility in discriminating osteogenic from non-osteogenic sarcomas. METHODS AND RESULTS Forty-eight pretreated osteosarcoma biopsies, including 26 whole-section cases and 22 tumours on tissue microarrays, and 36 non-osteogenic bone sarcomas were evaluated. Forty-five of 48 (94%) osteosarcomas showed nuclear immunoreactivity for SATB2 (all whole-slide sections showed expression). Positive SATB2 expression was observed in 11 of 22 (50%) undifferentiated pleomorphic sarcomas (UPSs), and in five of 11 (45%) fibrosarcomas; expression was absent in two pleomorphic rhabdomyosarcomas and in the one leiomyosarcoma. The sensitivity of SATB2 for osteosarcoma was 94%, and the specificity was 55%. Stronger-intensity staining was observed in osteosarcoma (P < 0.0001). CONCLUSIONS SATB2 is a sensitive marker for osteosarcoma; however, it is not specific, with expression being observed in other high-grade primary bone sarcomas. Intriguingly, the lack of specificity may suggest that the undifferentiated sarcomas (UPSs and fibrosarcomas) with SATB2 expression actually represent osteosarcomas that produce too little matrix to be detected with routine sampling or consist of osteoblast precursors that do not synthesize matrix.

Abstract
AIMS Desmoid-type fibromatosis (DF) is a rare benign myofibroblastic neoplasm of the connective tissue that is unable to metastasize but is associated with a high local recurrence rate. Nuclear β-catenin is the most commonly used histological marker of DF; however, clinical and biological predictive markers guiding the treatment and follow-up of DF are still lacking. Normally, β-catenin is regulated by the cytoplasmic multiprotein complex of adenomatous polyposis coli (APC), axin, casein kinase 1α (CK1α), and glycogen synthase kinase 3β (GSK-3β); this phosphorylates and degrades β-catenin, which would otherwise translocate to the nucleus. The aim of this study was to analyse the expression and localization of the β-catenin-protein complex of the Wnt pathway in cells isolated from DF patients. METHODS AND RESULTS We isolated cells from biopsies of DF patients, and demonstrated, by immunofluorescence and immunoblot analyses, that it is almost exclusively nuclear GSK-3β that colocalizes and interacts with β-catenin. The nuclear translocation of β-catenin and GSK-3β is not correlated with CTNNB1 mutations. In DF samples, the multiprotein complex is disrupted, as the cytoplasmic localization of APC and axin makes interaction with the nuclear β-catenin and GSK-3β impossible. CONCLUSIONS Our data suggest that GSK-3β is an additional DF marker with an important role in the aetiopathogenesis of this entity.

Abstract
BACKGROUND Desmoid tumors are neoplastic proliferations of connective tissues. The mutation status of the gene coding for catenin (cadherin-associated protein) beta 1 (CTNNB1) and trisomy 8 on the chromosomal level have been described to have prognostic relevance. PATIENTS AND METHODS In order to elucidate new molecular mechanisms underlying these tumors, we carried out a molecular analysis with a genome-wide human high-density single-nucleotide polymorphism (SNP) array, in 9 patients. RESULTS Single samples showed numerical aberrations on chromosomes (Chrs) 20 and 6 with either trisomy 20 or monosomy 6. No trisomy 8 could be detected. Recurrent heterozygous deletions were found in Chr 5q (including the APC gene locus, n = 3) and Chr 8p23 (n = 4, containing coding regions for the potential tumor suppressor gene CSMD1). This novel deletion in 8p23 showed an association with local recurrence. In addition, structural chromosomal changes (gain of Chrs 8 and 20) were found in a minority of cases. CONCLUSION The genomic alteration affecting the candidate gene CSMD1 could be important in the development of desmoid tumors.

Abstract
Extra-abdominal desmoid tumors are a significant cause of morbidity in patients with familial adenomatous polyposis syndrome. Understanding of the basic biology and natural history of these tumors has increased substantially over the past decade. Accordingly, medical and surgical management of desmoid tumors has also evolved. This paper analyzes recent evidence pertaining to the epidemiology, molecular biology, histopathology, screening, and treatment of extra-abdominal desmoid tumors associated with familial adenomatous polyposis syndrome.

Abstract
Treatment modalities for desmoid tumors have been changed because of the high recurrence rate, even after wide resection, and some cases experience spontaneous self-regression during clinical course. The treatment modality in our institutions before 2003 was surgical resection with wide surgical margin, however, meloxicam, which is a NSAID and a selective COX-2 inhibitor has been applied consecutively since 2003. We reviewed the previously reported outcomes of surgical and conservative treatment in our institutions. Among 30 patients receiving surgical treatment, 16 (53%) recurred. Younger age ( p < 0.05) was a significant poor factor. According to RECIST for meloxicam treatment, CR was in one, PR in 10, SD in eight, PD in one evaluated at 2011. Older age ( p < 0.01) was significantly associated with good outcome for meloxicam treatment. Results of the previous study indicated that surgical treatment alone could not control desmoid tumors, even with negative surgical margin. Considering the functional impairment resulting from surgery with negative surgical margin, a conservative and effective treatment modality with fewer complications is desired. Conservative treatment with meloxicam is a promising novel modality for patients with extra-abdominal desmoid tumors.

Abstract
Desmoid fibromatosis (also known as infantile or aggressive fibromatosis) is a rare soft tissue tumour that is occasionally seen in children. Although histologically benign, its growth pattern is highly aggressive often showing invasion of surrounding musculature and bone. Frequently found in cosmetically sensitive areas, complete excision can present a challenging problem. However, incomplete surgical excision is associated with high recurrence rates and although the disease responds to chemo and radiotherapy, both carry significant risks in young children. The management of four paediatric desmoid fibromatoses occurring in the midface is discussed. The recent and pertinent literature is comprehensively reviewed and an algorithm for the management of paediatric desmoid fibromatoses is proposed.

Abstract
A change in chromosome number, known as aneuploidy, is a common characteristic of cancer. Aneuploidy disrupts gene expression in human cancer cells and immortalized human epithelial cells, but not in normal human cells. However, the relationship between aneuploidy and cancer remains unclear. To study the effects of aneuploidy in normal human cells, we generated artificial cells of human primary fibroblast having three chromosome 8 (trisomy 8 cells) by using microcell-mediated chromosome transfer technique. In addition to decreased proliferation, the trisomy 8 cells lost contact inhibition and reproliferated after exhibiting senescence-like characteristics that are typical of transformed cells. Furthermore, the trisomy 8 cells exhibited chromosome instability, and the overall gene expression profile based on microarray analyses was significantly different from that of diploid human primary fibroblasts. Our data suggest that aneuploidy, even a single chromosome gain, can be introduced into normal human cells and causes, in some cases, a partial cancer phenotype due to a disruption in overall gene expression.

Abstract
Desmoid tumours (also called deep or aggressive fibromatoses) are potentially life-threatening fibromatous lesions. Hereditary desmoid tumours arise in individuals affected by either familial adenomatous polyposis (FAP) or hereditary desmoid disease (HDD) carrying germline mutations in APC. Most sporadic desmoids carry somatic mutations in CTNNB1. Previous studies identified losses on 5q and 6q, and gains on 8q and 20q as recurrent genetic changes in desmoids. However, virtually all genetic changes were derived from sporadic tumours. To investigate the somatic alterations in FAP-associated desmoids and to compare them with changes occurring in sporadic tumours, we analysed 17 FAP-associated and 38 sporadic desmoids by array comparative genomic hybridisation and multiple ligation-dependent probe amplification. Overall, the desmoids displayed only a limited number of genetic changes, occurring in 44% of cases. Recurrent gains at 8q (7%) and 20q (5%) were almost exclusively found in sporadic tumours. Recurrent losses were observed for a 700 kb region at 5q22.2, comprising the APC gene (11%), a 2 Mb region at 6p21.2-p21.1 (15%), and a relatively large region at 6q15-q23.3 (20%). The FAP-associated desmoids displayed a significantly higher frequency of copy number abnormalities (59%) than the sporadic tumours (37%). As predicted by the APC germline mutations among these patients, a high percentage (29%) of FAP-associated desmoids showed loss of the APC region at 5q22.2, which was infrequently (3%) seen among sporadic tumours. Our data suggest that loss of region 6q15-q16.2 is an important event in FAP-associated as well as sporadic desmoids, most likely of relevance for desmoid tumour progression.

Abstract
BACKGROUND/OBJECTIVES To report on the clinical presentation and outcome for 234 patients with extra-abdominal desmoids tumors. METHODS Since 1977, the authors have treated 234 patients with extra-abdominal desmoid tumors. The patients had an average age of 36.7 and 61% were female. The tumors arose adjacent to muscles or bones and the largest number were in the foot, shoulder thigh and calf. All of the patients were treated by primary surgery. Thirty-seven had additional radiation and eight had chemotherapy. RESULTS Local recurrence occurred in 39 patients and 23% of the patients required additional surgery. Of great concern were 24 patients who developed multiple sites metachronously, which required further surgery and in many cases caused disability. None of the patients died of disease but 5 required amputations. CONCLUSIONS The authors concluded that despite the benign nature of the disease, these patients are difficult to treat and the results are sometimes considerably less than optimal.

Abstract
Desmoid tumors are fibroblastic/myofibroblastic proliferations. Previous studies reported that CTNNB1 mutations were detected in 84% and that mutations of the APC gene were found in several cases of sporadic desmoid tumors lacking CTNNB1 mutations. Forty tumors were analyzed by comparative genomic hybridization (CGH). Karyotype and fluorescence in situ hybridization revealed a nonrandom occurrence of trisomy 8 associated with an increased risk of recurrence. We report the first molecular characterization including a large series of patients. We performed array CGH on frozen samples of 194 tumors, and we screened for APC mutations in patients without CNNTB1 mutation. A high frequency of genomically normal tumors was observed. Four relevant and recurrent alterations (loss of 6q, loss of 5q, gain of 20q, and gain of Chromosome 8) were found in 40 out of 46 tumors with chromosomal changes. Gain of Chromosomes 8 and 20 was not associated with an increased risk of recurrence. Cases with loss of 5q had a minimal common region in 5q22.5 including the APC locus. Alterations of APC, including loss of the entire locus, and CTNNB1 mutation could explain the tumorigenesis in 89% of sporadic desmoids tumors and desmoids tumors occurring in the context of Gardner's syndrome. A better understanding of the pathogenetic pathways in the initiation and progression of desmoid tumors requires studies of 8q and 20q gains, as well as of 6q and 5q losses, and study of the Wnt/beta-catenin pathway.

Abstract
Desmoid fibromatoses are benign, slow growing fibroblastic neoplasms, arising from musculoaponeurotic stromal elements. Desmoids are characterized by local invasion, with a high rate of local recurrence and a tendency to destroy adjacent structures and organs. Desmoid fibromatoses are rare in children, and though they may occur in the head and neck region, are extremely rare in the paranasal sinuses. Here we report a case of extraabdominal desmoid fibromatosis in a seven-year-old boy involving the sphenoid sinus, one of only six published reports of desmoid fibromatosis of the paranasal sinuses. The expansile soft tissue mass eroded the walls of the sphenoid sinus as well as the posterior ethmoid air cells extending cephalad through the base of the skull. We discuss the clinicopathologic features of this lesion, including structural and ultrastructural characteristics, and we review the literature regarding treatment and outcome.

Abstract
Desmoid tumors are benign tumors that exhibit varying degrees of local aggressiveness and diverse growth patterns. Magnetic resonance imaging remains the modality of choice for assessment of the nature and size of the soft-tissue lesion and involvement of surrounding structures. Treatment strategies include surgery, chemotherapy, hormonal therapy, and radiation therapy, either individually or in combination. Despite the benign nature of these tumors, multidisciplinary care is needed to provide combined treatment options. Chemotherapy in low doses is an excellent first-round treatment in any patient in whom contemplated local treatment may produce local morbidity and adjacent tissue injury.

Abstract
Aggressive fibromatoses, also known as desmoid tumours, are rare fibrous tissue proliferations with a tendency for slow, local infiltrative growth. There is an association with Gardner's syndrome and familial adenomatous polyposis. Histologically they are fairly bland with no abnormal mitoses or necrosis. They do not metastasize, but can cause significant morbidity through their locally destructive effects. Magnetic resonance imaging is the method of choice for diagnosis, pre-treatment planning and post-treatment follow-up. Surgical excision with a wide margin is the treatment of choice. However, there is a tendency for local recurrence and repeated excision may result in a poor functional or cosmetic outcome. Radiotherapy is used to reduce local recurrence rates after excision and is also used to treat inoperable tumours. Long-lasting remissions can be obtained. Treatment is now planned using modern three-dimensional conformal techniques, similar to those used in soft tissue sarcoma management. There is no definite dose-response relationship, but doses of 50-60 Gy in 1.8-2 Gy fractions are recommended. Systemic therapy has been used for lesions not controlled by surgery or radiotherapy, or less commonly, as a primary treatment. Tamoxifen and non-steroidal anti-inflammatory agents are used most often as they are relatively non-toxic, but there is limited experience with cytotoxic chemotherapy and biological agents. There are no randomised trials to help guide the management of this locally aggressive 'benign' tumour and treatment decisions are best made by the local soft tissue sarcoma multidisciplinary team.

Abstract
Benign fibrous (fibroblastic or myofibroblastic) soft-tissue tumors are a heterogeneous group of fibrous lesions with widely varied anatomic locations, biologic behavior, and pathologic features. The four broad categories of fibrous proliferation are benign fibrous proliferations, fibromatoses, fibrosarcomas, and fibrous proliferations of infancy and childhood. The first two categories include nonaggressive fibroblastic lesions such as nodular fasciitis, as well as fibromatoses that demonstrate more aggressive biologic behavior (eg, desmoid tumors). In adults, fibrous tumors are among the most common soft-tissue lesions encountered in clinical practice. MR imaging can be useful for defining the intrinsic signal characteristics, size, and compartmental extension of these lesions. Histologic features of the tumor also may be depicted on T2-weighted MR images. Hypocellular fibrous tumors with dense collagenous components tend to have lower signal intensity on T2-weighted images than do lesions that are more cellular or that contain greater amounts of extracellular myxoid matrix. When interpreting MR images of soft-tissue masses in adults, radiologists should be aware of the clinical behavior, common sites of occurrence, and histopathologic and imaging features of the common benign fibrous soft-tissue tumors.

Abstract
Desmoid tumors, also known as aggressive fibromatosis, are rare fibroblastic tumors that exhibit a wide range of local aggressiveness, from largely indolent to locally destructive. Understanding of the pathogenesis and the great heterogeneity in the natural history of desmoid tumors is invaluable to the development of therapeutic strategies. The optimal treatment protocol has not yet been established and, in many cases, a multidisciplinary approach including surgery, chemotherapy, and radiation therapy has been employed. The rarity of cases in even major tumor centers has traditionally limited the ability to study this disease. Several novel pharmacologic and biologic treatment approaches are actively being developed, although long-term follow-up is needed for their substantiation.

Abstract
Constitutional trisomy 8 mosaicism (CT8M) in liveborns is typically caused by mitotic non-disjunction and exhibits wide phenotypic variability. By contrast, CT8M due to meiotic errors usually results in miscarriage. We describe a case of CT8M due to a paternal meiosis II non-disjunction error. The patient, a 32-year-old woman, was phenotypically normal except for a history of recurrent aphthous ulcers since childhood and a 4-year history of macrocytosis. The ulcers were refractory to steroids, but responded well to thalidomide. To the best of our knowledge, this is the first report of CT8M due to meiotic non-disjunction in a phenotypically normal individual.

Abstract
Desmoid tumors are benign neoplasms of the fibromatosis group. Data on their acquired chromosomal changes are sparse and, therefore, we wanted to ascertain what genomic losses and gains these tumors may have incurred. DNA was extracted from a total of 26 formalin-fixed, paraffin-embedded desmoid tumors followed by comparative genomic hybridization (CGH) and interphase fluorescence in situ hybridization (I-FISH) analyses. Ten of 12 informative tumors were normal by CGH; the two abnormal ones had loss of chromosome 6 and loss of 6q and gain of chromosome 20, respectively. I-FISH analyses with an alpha-satellite probe specific for chromosome 8 of 26 desmoids, including one tumor that by karyotyping had +i(8)(q10), showed no evident abnormalities. An explanation for the relatively high frequency of genomically normal tumors by CGH seen in this study may be sought in the fact that as many as 10 of the 12 informative tumors were abdominal desmoids, a subset of tumors also previously found to exhibit genomic changes only rarely. It is therefore possible that abdominal desmoids might be non-neoplastic tumors or neoplastic tumors with genetic changes too small to be discovered by CGH, whereas desmoid tumors from other locations exhibit detectable genomic changes at a significantly higher frequency.

Abstract
PURPOSE To explore prognostic factors in surgically treated aggressive fibromatosis (extra-abdominal desmoid tumor). PATIENTS AND METHODS A total of 203 consecutive patients treated with surgery over a 35-year period at a single referral center were retrospectively reviewed. One hundred twenty-eight were first seen at our institution with primary disease, whereas 75 had a recurrent tumor. All patients underwent macroscopically complete resection. Margins were rated as negative in 146 (97 with primary tumors, 49 with recurrences) and positive in 57 (31 in primary, 26 in recurrences) patients. Median follow-up was 135 months. RESULTS Patients with primary disease had a better disease-free survival rate than those with recurrence (76% v 59% at 10 years). Presenting with a recurrence was also the strongest predictor of local failure in the multivariate analysis. In patients first treated for primary disease, size and site had prognostic significance, whereas microscopically positive surgical margins did not. In contrast, in patients with recurrence, there was a trend toward better prognosis if margins were negative (although this was not significant at multivariate analysis). CONCLUSION Presence of microscopic disease does not necessarily affect long-term disease-free survival in patients with primary presentation of extra-abdominal desmoid tumors. Thus, function-sparing surgery may be a reasonable choice when feasible without leaving macroscopic residual disease. In patients with recurrences, positive margins may more clearly affect prognosis, potentially necessitating adjuvant radiation in selected cases.

Abstract
Telomeres are the natural ends of eukaryotic chromosomes. In most organisms, telomeres consist of simple, repeated DNA with the strand running 5' to 3' towards the end of the chromosome being rich in G residues. In cases where the very end of the chromosome has been examined, the G-strand is extended to form a short, single stranded tail. The chromatin structure of telomeric regions often has features that distinguish them from other parts of the genome. Because telomeres protect chromosome ends from degradation and end-to-end fusions and prevent the loss of terminal DNA by serving as a substrate for telomerase, they are essential for the stable maintenance of eukaryotic chromosomes. In addition to their essential functions, telomeres in diverse organisms are specialized sites for gene expression. Transcription of genes located next to telomeres is repressed, a phenomenon termed telomere position effect (TPE). TPE is best characterized in the yeast Saccharomyces cerevisiae. This article will focus on the silencing properties of Saccharomyces telomeres and end with speculation on the role of TPE in yeasts and other organisms.

BACKGROUND This Phase II study was undertaken to assess the activity of methotrexate plus vinblastine in the treatment of patients with inoperable aggressive fibromatosis (AF) and to observe the evolution of the disease after such low-dose chemotherapy. METHODS Thirty patients with a median age of 27 years who were affected by primary (20%) or recurrent (80%), advanced, inoperable AF were treated with weekly methotrexate at a dose of 30 mg/m(2) plus vinblastine at a dose of 6 mg/m(2) for a median interval of 1 year. Patients with recurrent disease had received surgery, radiotherapy, tamoxifen, and antracycline-based chemotherapy. Tumor response was assessed in all patients as well as time to disease progression. RESULTS Eighteen patients (60%) showed stable disease or minor tumor shrinkage along with symptom relief. A partial response was detected in 12 patients (40%). No complete responses were observed, and no patients had tumor progression during treatment. Four patients received fewer than 15 cycles of chemotherapy, mainly because of severe myelotoxicity. One of these patients died of local disease progression 33 months later, and the other three patients were stable. After a median follow-up of 75 months, the 10-year actuarial progression free interval is 67%. CONCLUSIONS Methotrexate plus vinblastine given every 7-10 days for several months is associated with prolonged stable disease in a substantial subset of patients with advanced (inoperable) aggressive fibromatosis.

Abstract
Whether fibromatoses are neoplastic or reactive lesions has long been controversial and the relationship, if any, between the superficial and deep forms (desmoid tumors) are poorly understood. Clinical, pathologic, and cytogenetic data of 78 cases of fibromatosis were analyzed and correlated with each other. The results demonstrate that clonal chromosome aberrations are a common feature of this entity, being present in 46% of desmoid tumors, although less frequent in the superficial types (10%). In the deep-seated extra-abdominal fibromatoses, trisomies 8 and 20 and loss of 5q material were the only recurrent features. No correlation between +8 and local recurrence was found. Our findings provide additional evidence for the neoplastic nature of fibromatoses.

Abstract
BACKGROUND AND OBJECTIVES Fibromatoses of the extremities are rare and often recalcitrant to treatment. We evaluated the clinical and pathologic features of a group of extremity fibromatoses treated by surgical excision with or without adjuvant therapy to determine if any clinical or pathologic parameters were predictive of clinical outcome. METHODS Thirty-six extremity fibromatoses were evaluated. A number of clinical and histologic features were correlated with risk of local recurrence. RESULTS The cohort included 19 females and 17 males with ages ranging from 11-72 years (mean: 35 years), with 12 tumors of the upper and 24 tumors of the lower extremity. Tumors ranged in size from 1.5-15.5 cm (mean: 7.5 cm).Histologically, 26 were infiltrative, 3 had pushing borders and 7 had both. Mitotic counts ranged from 0-5/50 high-power fields (mean: 0.74). Surgical margins were positive in 22 cases. Seventeen patients were treated with postoperative adjuvant therapy including radiation therapy and tamoxifen. Follow-up information was available in 34 cases (from 1-202 months; mean: 83 months). Nineteen patients (56%) had recurrences, including 11 with multiple recurrences (range to first recurrence: 5-61 months; mean 23 months). Seventy-one percent of patients with a positive surgical margin and clinical follow-up had a local recurrence, compared to 31%with a negative surgical margin (P < 0.05). None of the other clinical or histologic parameters correlated with the risk for local recurrence. CONCLUSIONS Local control in fibromatoses of the extremities remains problematic. Aside from positive surgical margins, none of the other clinical or histologic parameters evaluated in this study were useful in predicting the risk of local recurrence.

Abstract
The karyotype of a malignant nerve sheath tumor with rhabdomyosarcomatous differentiation (malignant triton tumor) of a 58-year-old woman is reported. The tumor revealed an isochromosome for the long arm of chromosome 8 and an unbalanced translocation (1;13)(q10;q10) leading to a gain of the long arm of chromosome 1 as the sole karyotypic abnormalities.

Abstract
Fibrous lesions of the breast are challenging for a number of reasons. They occur infrequently and there is significant clinical, radiologic, and histologic overlap between reactive and neoplastic lesions, as well as with some nonfibrous lesions. Pure fibrous lesions of the breast encompass reactive conditions, such as scars and nodular fasciitis, and neoplastic entities, such as the distinct benign mammary myofibroblastoma, locally aggressive fibromatosis, and rare true sarcomas. In this review, we focus on nodular fasciitis, mammary myofibroblastoma, and primary mammary fibromatosis. We also briefly discuss spindle cell metaplastic carcinoma because it represents the most important differential diagnosis through its ability to closely simulate nodular fasciitis and fibromatosis. Caution should be exercised in the interpretation of fibrous lesions of the breast, especially if the tissue sample is limited. Int J Surg Pathol 8(2):99-108, 2000

Abstract
BACKGROUND Desmoid tumour (DT) is an uncommon locally invasive non-metastasizing neoplastic lesion. The aetiology of this tumour is unknown and its treatment is controversial. Twelve cases of DT are presented and the literature is reviewed. METHODS Twelve cases of DT treated at our institution during a 3.5-year period are analysed and the literature reviewed. Ten patients were referred with a primary tumour, one with local recurrence and one patient with a second primary desmoid tumour. One patient had multiple mesenteric DT (familial adenomatous polyposis coli-FAP), and in the remaining 11 patients the tumour was located in the abdominal wall in four, at an extremity in three, in the upper back in two patients, in the pelvis in one and retroperitoneally in one. RESULTS The largest mesenteric DT was marginally excised en bloc with total jejunectomy. In the remaining 11 DT, complete excision to microscopically tumour-free margins was possible in nine cases and to microscopically involved margins in two cases. At a mean follow-up of 22 months (range 7-38 months), one patient was alive with stable disease (Gardner's syndrome), 10 patients were alive and free of recurrence and one patient (9%) developed local recurrence which was re-excised-she is disease-free 10 months later. CONCLUSIONS Complete excision is the main modality of treatment for primary and recurrent DT. This is feasible in most cases except for tumours involving the base of the bowel mesentery. Surgical resection alone achieved local control of the tumour in most of the patients in this series (92%).

Abstract
Trisomy 8 and trisomy 20 are nonrandom aberrations in desmoid tumors. The presence of these trisomies in related benign fibrous lesions of bone has not been previously addressed. In this study, 22 specimens from 19 patients diagnosed with desmoid tumor, desmoplastic fibroma, periosteal desmoid tumor, osteofibrous dysplasia, or fibrous dysplasia were examined by cytogenetic analysis of short-term cultures and bi-color fluorescence in situ hybridization of cytological touch preparations or paraffin-embedded tissue with centromeric probes for chromosomes 8 and 20. Trisomy 8 and trisomy 20 were detected by molecular cytogenetic methodologies in 15 specimens, including 10 primary bone lesions. Traditional cytogenetic analysis revealed trisomy 8 in two cases of osteofibrous dysplasia. Our findings demonstrate that trisomy 8 and trisomy 20 are also nonrandom aberrations in histologically similar, but clinically distinct, benign fibrous lesions of bone.

Abstract
Cytogenetic and molecular cytogenetic analysis is reported in a series of 40 tissue samples from 36 patients with Dupuytren's disease, presenting as palmar and/or finger nodules. No consistent structural chromosome changes could be found. Instead, recurrent clonal numerical abnormalities were demonstrated in 22 of 40 tissue nodules, involving trisomies of chromosome 7 or 8 and loss of the Y chromosome. In addition, we showed that trisomy 7 and trisomy 8 were also present in non-dividing cells.

Abstract
The authors report the case of an adult female patient who developed a paraspinous thoracic fibromatosis (desmoid tumor) after undergoing resection of an intraspinal thoracic meningioma that was complicated by postoperative wound infection. To the best of the authors' knowledge, this is the first report of such a tumor occurring after resection of a spinal meningioma. Awareness of the development of postoperative fibromatosis and recognition of its association with wound sepsis is important. Although rare, this distinctive lesion should be considered in the differential diagnosis of the apparent rapid regrowth of otherwise indolent lesions including meningioma.

Abstract
DNA sequence copy number changes were studied by comparative genomic hybridization (CGH) in 28 desmoid tumors. Changes were detected in 12 tumors (43%) with a mean of 1.4 changes per sample (range: 1 to 7). Out of 12 tumors associated with pregnancy or Gardner's syndrome, only two displayed changes. The minimal common regions of the most frequent gains were 1q21 (39%), chromosome 20 (32%), and 9p12 (21%). No high-level amplifications were detected. Losses of DNA sequences were two times less frequent than gains and the minimal common regions of the most frequent losses were 6q16-q21 (14%), 5q14 (11%), and 13q21-q31 (11%).

Abstract
Desmoids are locally aggressive, non-metastasizing soft-tissue tumours, whose aetiology is still unclear. In patients affected with familial adenomatous polyposis (FAP), the incidence of desmoids is much higher than in the general population. The APC gene, which is responsible for FAP, is involved in the development of desmoids associated with this syndrome. In this study 16 sporadic and four FAP-related desmoids were analysed in order to investigate the possible involvement of APC in non-syndromic cases also. The 5' end (exons 1-11) and the coding portion of exon 15 of APC were screened using the in vitro synthesized-protein assay (IVSP). Exons 5, 6, 8-14, and a region of exon 15 spanning codons 1036-1634 were investigated by single-strand conformation polymorphism (SSCP) analysis. APC germline mutations were identified in all FAP patients, but not in sporadic cases. Somatic mutations were found in three FAP-associated desmoids (75%) and two sporadic tumours (12.5%). In one of the latter cases, both alleles were affected. These findings indicate a limited role of the gene in the development of desmoid tumours outside FAP.

Abstract
BACKGROUND Telomerase activity may be required for unlimited growth of cells and is repressed in most somatic tissues, but is detectable in immortal cell lines, germ cells, many malignancies and some benign lesions. Desmoids are proliferative, locally invasive, non-metastasizing fibromatous tumours which rarely regress. They occur frequently in familial adenomatous polyposis (FAP), causing significant morbidity and death. Telomerase activity was assayed in desmoids from patients with and without FAP to assess the role of telomerase in the development of these lesions, and its potential as a prognostic marker and possible target for treatment. METHODS Protein extracts from 11 desmoids from nine patients with FAP, and ten desmoids from ten patients without FAP, were analysed for telomerase activity by the telomeric repeat amplification protocol, a sensitive polymerase chain reaction-based assay. Six fibrosarcomas and a fibrosarcoma cell line were used as positive controls; all displayed telomerase activity. RESULTS No telomerase activity was detected in any of the 21 desmoids studied. CONCLUSION These results indicate that desmoid tumours are one of the intriguing exceptions to the emerging view that re-expression of telomerase activity accompanies the development of preneoplastic and neoplastic tissues, and suggest that alternative mechanisms may operate in these proliferative neoplasms.

Abstract
A total of 34 cases of infiltrating ductal carcinoma of the breast, not otherwise specified (NOS), were selected, based on the clinical stage of the disease (17 cases stage I and 17 cases stage II). The histologic grade and the DNA content of each tumor were evaluated. Each specimen was analyzed and blinded cytogenetically for the frequency of chromosome 8 copy number using fluorescence in situ hybridization (FISH). Among the informative samples, 16 cases were disomic (47%) and 18 cases (53%) were trisomic. Of the 16 disomic tumors, 13 cases (81%) were classified clinically as stage I disease and 3 cases (19%) were stage II disease. Of the 18 trisomic tumors, 4 cases (22%) were stage I, and 14 cases (78%) were stage II. Microscopically, all trisomic tumors were of high histologic grade and aneuploid when analyzed by flow cytometry. We inferred from these data that a subset of infiltrating ductal carcinomas (NOS) is characterized by chromosome 8 trisomy. This chromosomal abnormality correlates well with other markers that predicate aggressive biological behavior of the tumor. While this observation needs to be further extended, the data suggest that chromosome 8 copy number may be used as a possible marker to identify a subgroup of patients with infiltrating ductal carcinoma associated with a poor prognosis.
