Abstract
OBJECTIVE To evaluate the short-term prognostic value of matrix metalloproteinase 14 (MMP14) in muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS Expression of MMP14 and clinical information from The Cancer Genome Atlas (TCGA) were mined in MIBC patients to analyse expression differences and conduct survival analyses. The mRNA and protein expression levels of MMP14 in other tumours were analysed using Gene Expression Profiling Interactive Analysis (GEPIA) and The Human Protein Atlas. The expression level of MMP14 in bladder cancer (BC) cell lines and clinical samples and its clinical significance were indicated using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), Western blotting, and immunohistochemistry. The biological functions of MMP14 were investigated by examining cell migration using in vitro wound-healing assays and cell invasion using transwell invasion assays. Survival analyses were conducted with the collected clinical follow-up data. RESULTS Our study revealed that MMP14 is highly expressed in MIBC based, on both TCGA derived data and our clinical tissues (p<0.05). MMP14 is also highly expressed in head and neck cancer, renal cancer, pancreatic cancer and other cancers, as analysed using GEPIA and The Human Protein Atlas (p<0.05). Survival analyses of the TCGA data and our clinical follow-up data revealed high expression of MMP14 indicates a poor short-term prognosis in MIBC (p<0.05). Furthermore, downregulation of MMP14 suppressed BC cell invasion and migration abilities in vitro. MMP14 expression was closely correlated with tumour metastasis (p<0.05). T stage [hazard ratio (HR)=1.412, 95% confidence interval (CI)=1.121-1.779, p=0.003] and metastasis (HR=2.256, 95% CI=1.242-4.100, p=0.008) were unfavourable prognostic factors in BC patients. CONCLUSIONS In MIBC, MMP14 expression is upregulated and closely associated with disease progression and poor short-term prognosis.

Abstract
A 26-year-old man with unresectable inflammatory myofibroblastic tumor (IMT) presented with multiple metastases in the thoracic vertebra and lymph nodes as detected by positron emission tomography (PET) received chemotherapy with carboplatin plus paclitaxel. After three cycles of chemotherapy, fluorine-18-fluorodeoxyglucose (FDG)-PET/CT revealed tumor regression and significant reduction of FDG uptake in all lesions. The patient received six cycles of chemotherapy without any severe adverse event, and there was no sign of disease progression for seven months. This regimen is well tolerated and may be considered the treatment of choice for unresectable IMT.

Abstract
Even though skeletal muscle, making up about 40% of body weight, is the largest organ in the human body, metastasis from malignant lesions is rare. Among reports of metastasis, those involving the iliopsoas muscle are numerous but few reports involve resection. Reported here is one example we experienced where metastasis developed in the iliopsoas muscle following colectomy, resection was then made possible by radiotherapy and chemotherapy. The case involved a 71-year- old male in which a Hartmann procedure was performed for sigmoid colon cancer. The pathology was Type 3 (8 × 7 cm, adenocarcinoma( mod), ss or more, ly1, v1, n0, ow(-), aw or ew(+), stage II). Upon additional sampling, thermal degredation of neoplastic cells was shown and outpatient oral UFT was performed. Five years following surgery, lymphoadenopathy was noted in the area of the left iliac artery upon US and CT. PET showed a probable metastasis to the left iliopsoas muscle. Early esophageal and stomach cancer were diagnosed by GFT. The esophageal cancer was located 30-32 cm from the incisors, unstained, Borrmann type 1, penetrating deeper than the muscularis propria. Biopsy revealed a diagnosis of tubular adenocarcinoma. ESD was performed for the esophageal cancer and one month later, a total gastrectomy D1+β was performed. During surgery, the iliopsoas muscle tumor was determined to be large and impossible to resect. Radiotherapy of 10MV X-ray, 8 fields, 65-70 Gy/26 times for 6 . 5 weeks was performed for residual tumor but had no effect on tumor size. Fifteen courses of FOLFOX+bevacizumab were then performed. The tumor was markedly reduced in size, unidentifiable upon CT but showed slight uptake on PET and resection of the suspected residual tumor was performed. Histologically, atypical cells were shown in scarred muscle and connective tissue, however, degradation by chemotherapy was high. Residual tumor at resection margins was found, findings consistent with metastasis form sigmoid colon cancer. Taking into account the age and condition of the patient following surgery, chemotherapy was changed to S-1. Currently, 5 months after resection, there has been no recurrence.

Abstract
A case of myofibrosarcoma (IMT) of the brain and lung as well as the spinal cord is described. A 29-year-old male patient presented with fever (40 degrees C), malaise, vomitus, meningism and leukocytosis. Computer tomography identified a bleeding in the left frontal lobe. A bleeding angioma was suspected and an operation was performed. The histological examination could not reveal an exact diagnosis. Eight months after complete recovery from the first bleeding, the patient had a second intracranial temporo-occipital bleeding on the right side which has been removed operatively. A new lesion was seen in the left parietal white matter of the brain. A growing cavernoma was suspected and resection of the lesion was planned. Pre-operatively the patient suffered from hemoptysis and fever. The X-ray of the chest showed a pulmonary lesion in the left lower lobe. In the CT of the chest a large tumor in the left lower lobe of the lung and additionally a cystic structure in the mediastinum was seen. The histological examination of this tumor identified an inflammatory myofibroblastic tumor (IMT). The left parietal lesion has been resected after the thoracic operation. The brain lesions were estimated to be metastases of the IMT of the lung. In the further clinical history the patient developed a large spinal cord metastasis of the thoracic spine. The metastatic development of the tumor reported in this case is unusual. The current therapy of these tumors consists of complete tumor resection and further clinical controls. However, due to the localization and the extension of some lesions in the present case, the complete resection has not been possible. There is no proven role of chemotherapy and radiation therapy. The patient died due to the pulmonary deterioration.

Abstract
Inflammatory myofibroblastic tumor (IMT) is a rare childhood neoplasm. The natural history of this disease is poorly understood. Recently chromosomal rearrangements involving the anaplastic lymphoma kinase (ALK) gene have been implicated in this tumor. We have studied a case of ALK-positive soft tissue IMT showing clinical and morphologic features of malignancy. Interphase fluorescence in situ hybridization demonstrated ALK rearrangements in both primary and metastatic lesions. Rapid amplification of cDNA ends (5'RACE) identified cysteinyl-tRNA synthetase (CARS) gene fused to ALK, which predicts an in-frame chimeric protein with the preserved functional catalytic domain of ALK at the C terminus. Amplification and sequencing of tumor DNA confirmed the breakpoint at the genomic level. Restriction analysis of DNA from primary soft tissue and recurrent lung tumors showed identical patterns, indicating the same clonal origin of both lesions. Western blot analysis with C-terminus ALK antibody showed expression of an aberrantly sized chimeric protein of approximately 130 kd in tumor tissue. This is the second case of IMT demonstrating CARS as the ALK fusion partner, which confirms the recurring involvement of ALK in IMT by a common genetic mechanism. Moreover, identical clonality of separate lesions involving different sites supports metastasis in IMT.

Abstract
Inflammatory myofibroblastic tumor, also referred to as inflammatory fibrosarcoma, is a rare tumor composed of myofibroblastic spindle cells of uncertain etiology and disputed nosology. We report a case of inflammatory myofibroblastic tumor of the omentum with involvement of the bone marrow in an 18-year-old man. Histologic and immunohistochemical studies of the abdominal mass and bone marrow were consistent with inflammatory myofibroblastic tumor. Additionally, fluorescence in situ hybridization using a probe specific for the ALK gene showed disruption of the gene. The literature is reviewed with emphasis on the ability of inflammatory myofibroblastic tumor to recur, metastasize, and cause mortality.

Abstract
BACKGROUND Inflammatory myofibroblastic tumors (IMT) represent a spectrum of neoplasms that occur in the mesentery and retroperitoneum and less frequently in the mediastinum of children and young adults. Transformation into inflammatory fibrosarcoma and metastases are rare. CASE REPORT We report the case of a 16-year-old patient with an inflammatory myofibroblastic tumor of the mesentery with mediastinal metastases. Partial remission was obtained by chemotherapy with ifosfamide, dactinomycine, and vincristine. Two months later, relapse with infiltration of the meninges developed, and the patient died. CONCLUSION This case demonstrates unusual features of an IMT: presentation with metastases, excellent response to chemotherapy, dissemination to the CNS.

Abstract
BACKGROUND Peritoneal spread of tumour cells is a major source of morbidity and mortality in patients with colorectal cancer. In order to develop strategies to prevent intraperitoneal dissemination and to treat peritoneal carcinomatosis, the spread of tumour cells in the peritoneal cavity was studied. METHODS Two million CC531 colon carcinoma cells were administered intraperitoneally in five groups of eight rats. The rats were killed after 1, 2, 4 and 8 hours and 3, 7, 14 and 21 days. After inspection of the abdominal cavity, samples of blood and ascites were taken. Liver, spleen, omentum, mesentery, diaphragm, parathymic lymph nodes and lungs were removed for histology and immunohistochemistry. RESULTS No abnormalities were seen in the abdominal cavity until day 3. Subsequently the peritoneum and omentum became thickened and after 21 days all rats had haemorrhagic ascites and peritoneal carcinomatosis. The abdominal fluid contained tumour cells at all stages. The number of tumour cells decreased in the first 8 hours, and increased thereafter. At microscopy the peritoneum was completely covered by tumour cells after 3 days. Tumour cells concentrated in the milky spots (MS) of the omentum within 4 hours. The size of the MS increased as a result of an increase in number of tumour cells and macrophages. After 7--21 days the MS were completely replaced by tumour cells and new MS were formed. In the diaphragm tumour cells invaded the lymphatic lacunae after 8 h, and obliterated these after 3--7 days. Also invasion of the muscle fibres was seen after 3 days. Microscopically no tumour cells were found in blood, liver, spleen, parathymic nodes and lung. CONCLUSION After intraperitoneal administration of CC531 colon carcinoma cells, tumour cells spread throughout the abdominal cavity, and concentrate in the milky spots of the greater omentum, the paracolic gutters, the subhepatic and subphrenic spaces and in the lymphatic lacunae of the diaphragm.

Abstract
The concept of soft tissue sarcomas composed predominantly of myofibroblasts has been controversial. We examined a series of such lesions of low- and intermediate-grade malignancy to further define their clinical and pathologic features. Histologic appearances of four cases diagnosed as myofibrosarcoma by electron microscopy were reviewed. Eleven additional cases with similar morphology were then identified from 249 tumors originally indexed as fibrosarcoma. Electron microscopy was performed on five of these, and immunohistochemistry was carried out on all cases for which material was available. There were 11 men and 4 women aged 33 to 73 years (median, 54 yrs; mean, 53 yrs). Lesions mainly involved the head and neck, extremities, and trunk and ranged in size from 1.5 to 12 cm. The tumors were composed of bland or pleomorphic stellate to spindled cells with eosinophilic cytoplasm and tapered nuclei in a collagenous stroma; 10 were grade 1 and five were grade 2. All sarcomas displayed fascicular or storiform patterns, and some of the grade 1 lesions superficially mimicked nodular fasciitis. Electron microscopy of nine cases showed myofibroblastic differentiation, and immunohistochemistry showed smooth muscle actin in 13 of 15 cases, muscle-specific actin in 7 of 9, desmin in 6 of 14, and cytokeratin in 0 of 11. Four of nine grade 1 and three of four grade 2 tumors recurred (one twice), and one grade 2 tumor metastasized to the lungs. Myofibrosarcomas are indolent low-grade or occasionally aggressive intermediate-grade sarcomas which can be recognized by light microscopy. Their clinical importance lies in the resemblance, particularly of low-grade examples, to reactive or pseudosarcomatous conditions.

Abstract
Inflammatory myofibroblastic tumor is a rare gastrointestinal neoplasm. The authors report the case of a 5-year-old girl who initially presented with gastric outlet obstruction secondary to an inflammatory myofibroblastic tumor along the lesser gastric curvature. A subtotal gastrectomy and wedge resection of a left hepatic lobe nodule were performed. Obstructive jaundice developed one month postoperatively. Computerized tomography, percutaneous transhepatic cholangiography, and selective celiac and mesenteric arteriography showed a mass that involved the left hepatic lobe, with concomitant high-grade biliary obstruction and portal venous encasement. Percutaneous biliary drainage was performed. During laparotomy, the tumor was found to be unresectable, and the patient was referred to the Liver Transplant Service at The Children's Hospital of Philadelphia. A total hepatectomy with temporary portocaval shunt was performed, leaving the inferior vena cava in situ. At the back table, an ex vivo left trisegmentectomy was performed, followed by reimplantation of the posterior segment of the right hepatic lobe. The reimplanted liver segment functioned poorly, and completion hepatectomy with portocaval shunt was performed 24 hours postoperatively, because of severe coagulopathy, intraabdominal bleeding, and hemodynamic instability. The patient's condition stabilized, and she was listed for urgent liver transplantation. The anhepatic state was managed with intermittent plasmapheresis. She had transplantation 72 hours later, and was discharged from the hospital 3 weeks postoperatively after an uneventful recovery. She remains disease-free and has normal liver function 8 months after transplantation.

Abstract
The authors report the case of a 2-year-old boy with a recurrent and locally metastasizing, spindle cell, vascular tumor with histiocytoid cells involving the skin, subcutaneous tissue, and muscle of the right forearm, the right distal radius and ulna, and multiple lymph nodes of the right axilla. Diagnoses of hemangioma, hemangiopericytoma, angiomatosis, spindle cell hemangioendothelioma, and malignant hemangioendothelioma were made on successive excision specimens. The soft tissue of the right arm became diffusely enlarged, and a severe syndrome developed that was similar to that described by Kasabach and Merritt. The limb was amputated above the elbow, the axillary lymph nodes were cleared, and a total dose of 6,000 centigrays axillary radiation was given. After operation, the Kasabach-Merritt syndrome resolved. Despite the lymph node metastases and multiple tissues involved, the patient has remained well 6 years after surgery. Although the tumor exhibited some of the histologic features of a spindle cell hemangioendothelioma, the low-grade aggressive behavior resembled that of an epithelioid hemangioendothelioma. The reported case cannot be classified into any of the recognized categories or subdivisions of vascular tumors.

Abstract
A case of a granular cell tumor with a malignant behavior is described. Several repeated biopsy specimens, a resection specimen, and the metastatic lesions were compared with one another. Consecutive specimens showed increasing atypia. Electron microscopy of the metastatic lesions confirmed the granular cell nature of the tumor. The historic aspects of histogenesis are briefly discussed. The findings agree with a presently accepted origin from a primitive mesenchymal cell.

The entity known as "leiomyomatous hamartoma," a term that has been used in reference to metastatic smooth muscle neoplasms of uterine origin (MSMNUO), is uncommon. Several articles have dealt with clinical and light microscopic aspects of this lesion. Four reports on the ultrastructure of this type of neoplasm have been published, but they have been primarily concerned with its smooth muscle component. Much controversy exists as to whether the glandular elements are part of the neoplastic process or preexisting pulmonary elements. This ultrastructural study confirms that the gland-like spaces represent entrapped alveoli and terminal respiratory bronchioles.

Abstract
The authors report a case of chest skeletal muscle involvement by recurrent adenocarcinoma of the breast, in which individual myofibers were invaded by breast carcinoma cells. This unusual type of skeletal muscle involvement is especially interesting because it is known that the sarcolemma of skeletal myofibers is very resistant to enzymatic, mechanical, and chemical breakage.
