[Rectal Mucinous Cancer with Submucosal Tumor-Like Morphology Preoperatively Diagnosed Using EUS-FNAB - A Case Report].

A man in his 70s presented with a chiefcomplaint ofbleeding during bowel movements. Subsequent colonoscopy revealed a submucosal tumor-like elevated lesion ofapproximately 4 cm situated in the sigmoid section ofthe rectum. EUS-FNAB was performed, and the lesion was identified as mucinous cancer.

[A Case of Anal Canal Squamous Cell Carcinoma Detected with Anal Stenosis Eight Years Following Resection for Rectal Adenocarcinoma].

An 89-year-old woman underwent low anterior resection for rectal adenocarcinoma(Ra, pT3N0M0, pStage II , Cur A)in 2008. In February 2016, she underwent an outpatient examination because of a defecation disturbance. Lower gastrointestinal endoscopy was performed and the stenotic region was biopsied.

[HER2-Positive Advanced Gastric Cancer with Disseminated Intravascular Coagulation and Diffuse Bone Marrow Carcinomatosis Successfully Treated with S-1/Trastuzumab Chemotherapy--A Case Report].

Trastuzumab, a humanized monoclonal antibody against human epidermal growth factor receptor 2 (HER2), has been proven to result in a survival benefit for the treatment of patients with HER2-positive advanced gastric cancer (AGC). However, data are lacking for the treatment of those with disseminated intravascular coagulation (DIC) and diffuse bone marrow carcinomatosis. A 77-year-old woman presented with back pain and fatigue since 2 months.

Capsule Endoscope Aspiration after Repeated Attempts for Ingesting a Patency Capsule.

Capsule endoscope aspiration into the respiratory tract is a rare complication of capsule endoscopy. Despite the potential seriousness of this complication, no accepted methods exist to accurately predict and therefore prevent it. We describe the case of an 85-year-old male who presented for evaluation of iron deficiency anemia.

[A study on nine cases of mucocele of the appendix].

A clinicopathological study was made on 9 cases of mucocele (8 cases of adenoma and 1 case of adenocarcinoma) of the appendix treated at the hospital in the recent 12 years. With abdominal CT, correct preoperative diagnosis was successfully made in 7 out of 9 cases of mucocele of the appendix. Two cases of mucocele of the appendix were diagnosed as peritoneal pseudomyxoma before surgery.

Antitumor effect of intratumoral administration of bone marrow-derived dendritic cells transduced with wild-type p53 gene.

Purpose: Dendritic cells (DCs) are attractive effectors for cancer immunotherapy because of their potential to function as professional antigen-presenting cells for initiating cellular immune responses. The tumor suppressor gene p53 is pivotal in the regulation of apoptosis, and approximately 50% of human malignancies exhibit mutation and aberrant expression of p53. We investigated the antitumor effect of intratumoral administration of bone marrow-derived dendritic cells transduced with wild-type p53 gene.
