ABSTRACT: A 72-year-old man was admitted to our hospital complaining of upper abdominal pain and back pain. Advanced gastric cancer was found at the fundus of the stomach, and severe dysplasia was found at the lower esophagus. We proceeded with neoadjuvant chemotherapy (S-1+CDDP) because the lymph nodes in the lesser curvature of the stomach were metastasized and invasion of the pancreas and some vessels was suspected by computed tomography. The tumor size was reduced remarkably, the esophageal dysplasia disappeared after preoperative chemotherapy, and we were able to perform total gastrectomy.

ABSTRACT: A 59-year-old man realized a left lower abdominal pain and palpable mass about a month ago. He was admitted to our hospital because of the pain and high fever. Blood examinations revealed high levels of white blood cell count and CRP. Ultrasonography showed a wall thickness of the descending colon and 7 cm cystic mass with air around. Moreover, a 6 cm cystic mass was found an outside of the ascending colon. We first treated with antibiotics under the diagnosis of abscesses because of perforation of diverticulum. Colonoscopy revealed an obstructing tumor in descending colon and biopsy specimens of the tumor showed adenocarcinoma. The preoperative diagnosis of the right side tumor was unclear. We performed a partial resection of the descending colon, and the tumor outside of the ascending colon was resected. The pathological diagnosis of the tumors was both mucinous carcinoma of the colon. Mucinous carcinoma tends to be more found in the right side of the colon than in the left side. The rate of lymph node metastasis and dissemination is higher than that in differentiated adenocarcinoma. We report a rare case of mucinous carcinoma originated from the left side of the colon with a solitary dissemination in opposite side of the abdomen.

ABSTRACT: A 71-year-old man began feeling a lower abdominal pain at bowel movement about one year ago. He was found to have a pelvic tumor during a health examination and referred to our hospital for further evaluation. CT and MRI scans demonstrated a giant pelvic tumor, 10 cm in size, which compressed the rectum. The likely preoperative diagnosis was leiomyosarcoma from the rectum or neurilemoma. To regulate intraoperative hemorrhaging and to reduce the tumor size, angiography was performed at two days before the operation and embolization of the tumor vessels was done. He had a tumor resection and a low anterior resection of the rectum and a transient colostomy of the ascending colon without blood transfusion. The resected tumor was covered with thin yellowish-white capsule with smooth surface, elastic hard on palpation, and was measured 10.5 × 9 × 10.5 cm, and weighted 320 g. The pathological diagnosis was neurilemoma (schwannoma) consisting both Antoni type A and Antoni type B sections.
