Gastrointestinal stromal tumors (GISTs) have been reported to occasionally occur in patients with neurofibromatosis type 1 (NF-1), and many cases have had multiple lesions predominantly involving the small intestine. We report herein a case of multiple GISTs associated with NF-1 from whom laparoscopic surgery was beneficial. In a 79-year-old female admitted(More)
Integrin alpha4beta1 is a receptor for vascular cell adhesion molecule-1 and fibronectin. It is important in lymphopoiesis, inflammatory recruitment of leukocytes, and other situations that require cell adhesion to the vascular endothelium. The avidity of the cells expressing alpha4beta1 integrin can be rapidly changed by chemokines and chemoattractants.(More)
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract arising from Cajal's cells and expressing c-kit. In a consensus report, the clinical behavior of GISTs was categorized into risk classes according to the tumor size and mitotic count. We analyzed the risk categories based on GIST patients who(More)
An unusual case is described in which an abdominal wall and thigh abscess was an initial symptom of ascending colon cancer. A 76-year-old woman was referred to our hospital for investigation of fever and abdominal and thigh swelling. Computed tomography revealed a right abdominal wall, retroperitoneal, psoas and thigh abscess formation suspected to be(More)
The tree pattern matching problem is, given two labeled trees P and T , respectively called pattern tree and target tree, to find all occurrences of P within T. Many studies have been undertaken on this problem for both the cases of ordered and unordered trees. To realize flexible matching, a kind of variable-length-don't-care's (VLDC's) have been(More)
We present a case in which chemoradiation therapy was effective in a geriatric patient with Stage IV anal canal cancer. The patient is an 81-year-old woman who complained of proctorrhagia and anal pain. She was referred to us by her family doctor who suspected rectal cancer. Tumors as large as 6.5 cm in diameter mainly on the right side of the rectum as(More)
Autoradiography (ARG) has been used for quantitative analysis of the cerebral blood flow using <sup>123</sup>I-IMP, and the regional cerebral blood flow (rCBF) can be assessed more accurately with scatter and attenuation correction. Currently, the filtered back projection (FBP) method is generally used for image reconstruction. However, we anticipate(More)
Breast cancer with cartilaginous and/or osseous metaplasia is a type of metaplastic carcinomas and is a rare disease. We report the case of a 49 year-old female who underwent right mastectomy for a large breast tumor. Histological examinations revealed a mixed tumor with both stromal and epithelial elements;the stroma showed poor differentiated(More)
Case 1 involves a 60-year-old woman who underwent surgery (breast total resection[Bt]plus axillary lymph node resection [Ax]) for the treatment of carcinoma of the right breast when she was 37 years of age. She underwent another surgery due to cancer recurrence in the right musculus pectoralis major when she was 50 years of age. The right fourth rib and the(More)
The first case of dural metastasis occurred in a 60s years old woman, who presented with bone metastasis to the right breast. Nine months later, disorientation and left hemiplegia developed, the right coronal bone metastasis enlarged, and dural metastases were detected close to the tumor, as observed by using cranial magnetic resonance imaging (MRI).
