  • Ascending Colon Carcinoma with Intestinal Intussusception Complicated by Liver Abscess—A Case Report—

    　View Summary

    <p>Colorectal cancer causing abscesses in distant organs is rare. In this report, a patient with a liver abscess associated with ascending colon cancer causing intussusception is described. A 73-year-old woman presented with bloody stools. Colonoscopy showed ascending colon cancer. Blood tests at the initial visit showed severe inflammation and anemia. On contrast-enhanced computed tomography (CT), a low-density area was seen in the right lobe of the liver, and the patient was diagnosed with liver metastasis or liver abscess. Since antimicrobial therapy failed to improve the inflammation, a right hemicolectomy were performed. The patient was discharged after an uneventful postoperative course. Positron emission tomography showed a nodule in the right lobe of the liver with hyperaccumulation of fluorodeoxyglucose, which had markedly shrunk, leading to the diagnosis of liver abscess. On histopathological examination, the diagnosis was pStage IIIb, and CapeOX was initiated, though it was discontinued after one course. On one-year postoperative CT, no evidence of liver abscess or recurrence of colon cancer was seen. Colon cancer is a very rare cause of liver abscess. The cause of the liver abscess in this patient was presumed to be a transportal infection due to the intussusception secondary to colorectal cancer.</p>

    　View Summary

    <p>A 60-year-old woman who had been attending the outpatient's clinic of nephrology in our hospital because of systemic scleroderma and microscopic polyangiitis developed melena. Gastrointestinal endoscopy showed no abnormal findings, but a small intestinal capsule endoscopy revealed a submucosal tumor with ulceration in the ileum and a submucosal tumor on its anal side. The patient was referred to our department for uncontrollable bleeding with severe anemia (Hb 4.1 g/dL). Intraoperative findings revealed submucosal tumors 30 cm and 100 cm distant from the Bauhin valve. Intraoperative endoscopy revealed no findings other than the two lesions. A partial resection of the small intestine was performed including both lesions. Histopathological examination revealed spindle-shaped tumor cells forming a bundle and cord-like arrangement and positive for Epstein-Barr virus-encoded RNA in situ hybridization (EBER-ISH). EBV-associated small intestinal leiomyosarcoma is a rare disease and we report this case with a review of the literature.</p>

  • Primary Neuroendocrine Tumor Arising with a Retroperitoneal Mature Cystic Teratoma in an Adult: A Case Report

    Hayashi Yuki, Kinjo Tatsuya, Nishigaki Taishi, Miyagi Yoshihiro, Nakagawa Yutaka, Takatsuki Mitsuhisa

    The Japanese Journal of Gastroenterological Surgery ( The Japanese Society of Gastroenterological Surgery )  54 ( 4 ) 293 - 301   2021.04

    Type of publication: Research paper (scientific journal)

    　View Summary

    <p>A 10-cm pelvic tumor was incidentally detected in a 26-year-old woman in screening during pregnancy. Laparoscopy revealed a retroperitoneal tumor, which was suspected to be malignant because a solid lesion was found adjacent to the cystic lesion. She was then referred to our hospital for treatment. Abdominal contrast-enhanced CT and MRI showed a multicystic tumor with an enhanced small nodule at the dorsal side of the tumor that was found in front of the sacrum. Surgical resection was performed and the pathological findings after surgery revealed that the tumor was a retroperitoneal mature cystic teratoma and the small nodule was a neuroendocrine tumor (NET). The clinical course after surgery was unremarkable and the patient was discharged on the 7th day after surgery. Retroperitoneal mature cystic teratomas are relatively rare in adults. Since it has been reported that the frequency of malignant transformation increases with age and the prognosis is poor after this transformation, early surgery is recommended. We report this case as a very rare example of a retroperitoneal mature cystic teratoma containing a NET in an adult, and we include a literature review.</p>
