PURPOSE: To investigate the relationship between metal content of hepatocellular carcinoma (HCC) and signal intensity pattern on magnetic resonance images. MATERIALS AND METHODS: The patterns 59 HCCs 3 cm in diameter or smaller were correlated with histologic findings content. RESULTS: high T1-weighted images demonstrated more steatosis (P = .035) higher copper .008) than did surrounding hepatic parenchyma. T2-weighted clear cells .001) intensities related to a lower degree differentiation,...

Colorectal schwannomas are rare and usually benign gastrointestinal mesenchymal tumors. However, these tumors often overtreated, possibly owing to misleading malignant potential. To our knowledge, there have been no previous reports of ascending colon schwannoma preoperatively diagnosed as schwannoma. Herein, we report a case accurately by endoscopic biopsy successfully treated wedge resection. The patient was 76-year-old woman with complaints bloody stool. She had relevant past medical...

Abstract Background Automatic staplers are often used to reconstruct the digestive tract during surgeries for gastric cancer. Intragastric free cancer cells adhering automatic may come in contact with laparoscopic port area and progress site recurrence. This study aimed investigate presence/absence of surgery using cytological examinations. We further determined positive predictive clinicopathological factors clinical implications attached staplers. Methods included 101 patients who...

Serine/threonine kinase 11 (<i>STK11</i>) is known as a critical tumor-suppressor gene that frequently mutated in broad spectrum of human cancers. Among these, the p.F354L mutation <i>STK11</i> has been identified sporadic colon or lung cancer cases. Here, we report case 75-year-old male patient who underwent surgical treatment for multiple tumors gastrointestinal system. Genetic mutations were screened all resected samples, including duodenal high-grade adenoma,...

We present an 84-year-old female patient with a colostomy for pelvic recurrence of esophagogastric junction cancer (T3 N2 M0, StageIIIA). Four months postoperatively, she complained cessation output and abdominal pain. The was stenosed owing to the progression peritoneal metastases. placed self-expanding metallic stent (SEMS) via site. Her distention improved once passed stool. She started eat from next day discharged hospital 11 days later. Stenting malignant stenosis may effectively...

Duodenal tumors with a sporadic adenoma-carcinoma sequence are extremely rare. For such clinically suspected cases without specific family history, performing comprehensive gene search is important to understand the germline mutation background. We present 68-year-old woman genetic or familial history of adenomatous polyposis (FAP), Peutz-Jeghers syndrome, Lynch syndrome who presented Kosei Hospital, Japan, exertional dyspnea induced by abdominal pain lasting 3 weeks. A duodenal tumor was...
