Cytomegalovirus (CMV) infection has been reported to be a cause of refractory ulcerative colitis (UC). We herein report a case of refractory ulcerative colitis complicated by CMV infection requiring surgery. A 22-year-old man was admitted to our hospital with lower abdominal pain and bloody diarrhea. Under a diagnosis of acute UC, he was treated with prednisone 60 mg/day and sulfasalazine. Since his symptoms appeared to improve, the prednisone dosage was gradually reduced to 20 mg/day. After 5 months, he had an unexpected flare-up with fever and fresh anal bleeding. Colonoscopy demonstrated a punched out ulcer in the sigmoid colon. Biopsies by colonoscopy revealed cytomegalic inclusion bodies. Serologic and immunologic studies also suggested a recent CMV infection. Under a diagnosis of intractable UC complicated by a CMV infection, ganciclovir therapy was carried out, and the steroid therapy was tapered. Although the serum antigenemia became negative after the antiviral therapy, follow-up colonoscopy confirmed the severe stenosis after the punched-out ulcer healed completely. Since his symptoms did not improve, it was necessary to perform an elective proctocolectomy despite antiviral therapy. He was discharged with an uneventful postoperative course. It is important to recognize CMV colitis as a complication of inflammatory bowel disease, particularly in severe steroid-resistant colitis. Furthermore, in cases which fail to respond to antiviral treatment, the patient may ultimately require surgery.

Aggressive angiomyxoma (AA) is a rare mesenchymal tumor that preferentially involves the pelvic and perineal regions, and is characterized by frequent local recurrences. We describe here a case of large AA in a 31-year-old woman. The patient was admitted to our hospital with a mass in the perineal region, associated with severe menstrual pain. Although her past medical history was unremarkable, she had spotty pigmentation on the lips. Magnetic resonance imaging showed a large mass in the abdominal pelvis traversing the pelvic diaphragm just to the right of the anus, and the border between the tumor and the rectal wall was indistinct. Pathology examination of a frozen intraoperative specimen suggested AA, and, therefore, we completely resected the tumor, using a combined abdominoperineal approach. The tumor was attached to the right wall of the rectum and the pelvic diaphragm between the anus and the puborectalis. The patient recovered uneventfully and there has not been any evidence of local recurrence for 3 years postoperatively. We consider that abdominoperineal resection may be an appropriate treatment for a large AA infiltrating to the perirectal tissues, because the high recurrence rate of this disease has been attributed to incomplete surgical excision.

Abstract We describe herein the case of a patient in whom recurrent liver metastases from gastric cancer were successfully treated by performing repeated hepatic resections. A 63-year-old man underwent a total gastrectomy with regional lymph node dissection for an advanced gastric cancer on November 17, 1992, the pathological findings of which confirmed a diagnosis of well-differentiated tubular adenocarcinoma, ss, INFα, ly1, v0, n1(+). Follow-up computer tomography (CT) and ultrasonography scans done 7 months after the gastrectomy revealed a metastasis in the liver S5, and a partial resection of S5 was performed on July 5, 1993. Subsequently, on November 17, 1994, an anterior segmentectomy of the liver was performed for a liver metastasis in the liver S8, then on August 11, 1998, a partial resection of the liver S6 was performed for a metastasis in the liver S6. The pathological findings of each liver specimen resected were compatible with metastatic adenocarcinoma from the primary gastric cancer. The liver tumors were expansive-growing tumors with capsules and massive necrosis. The patient is currently well with no evidence of recurrence on repeat CT scans, 6 years 6 months since-the initial gastrectomy, and 5 years 10 months since the first hepatic resection.

Abstract We report herein a rare case of diverticulitis causing a high serum level of carbohydrate antigen (CA) 19-9. A 52-year-old man was admitted to our hospital with lower abdominal pain. Laboratory data showed evidence of inflammation and a high serum level of CA 19-9 (370 U/ml). Computed tomography demonstrated thickening of the wall of the sigmoid colon. He was diagnosed as having diverticulitis of the sigmoid colon and was treated with antibiotics. Although his symptoms improved, the presence of a malignancy such as colorectal cancer could not be completely ruled out because of the persistently high serum level of CA19-9. A laparotomy was performed and the sigmoid colon was found to be adherent to the bladder. Under a diagnosis of diverticulitis, a sigmoidectomy was performed. Pathological examination revealed diverticulitis of the sigmoid colon, but there was no evidence of malignancy in the resected specimen. The serum CA19-9 level decreased to normal postoperatively and immunohistochemical staining revealed CA19-9 antigen in the cytoplasm of the diverticular epithelium. Therefore, a possible explanation for the high level of this tumor marker was diverticulitis of the sigmoid colon.

PurposeWe report four cases of Crohn’s disease (CD)-associated colorectal cancer (CRC) in our department.Case 1A 42-year-old Japanese man had a 14-year history of ileocolon CD. He had a history of an ileocecal resection and a stricture plasty. At the age of 42, sigmoid colostomy was performed because of the deterioration of the anal stenosis. After this operation, the perianal pain had remained, and a magnetic resonance imaging scan revealed a rectal tumor.Case 2A 30-year-old Japanese man had a 13-year history of ileocolon CD. He had a history of an ileostomy, a subtotal colectomy, and ileo-rectal anastomosis. At the age of 30, he had perianal pain, and a colonoscopy revealed a rectal cancer. An abdomino-perineal resection of the remnant rectum was performed.Case 3A 46-year-old Japanese man had a 9-year history of ileocolon CD. He experienced abdominal fullness. Colonoscopy revealed an ascending colon cancer. He underwent a subtotal colectomy and ileo-rectal anastomosis.Case 4A 33-year-old Japanese woman had a 16-year history of ileocolon CD. She had no changes in symptoms of CD. Surveillance colonoscopy revealed a transverse colon cancer. She underwent a subtotal colectomy and ileo-rectal anastomosis.ConclusionAs the number of patients with CD and with CD-associated CRC has increased in Japan, CD-associated CRC, as noted in these patients, should be kept in mind in the management of patients with CD. In addition, a surveillance system of patients with CD should be established and should prompt further study about CD-associated CRC.

A 67-year-old Japanese man complained of a painful lump in his anus. He had a 15-month history of myelodysplastic syndrome (MDS) and had been diagnosed with MDS overt leukemia. A solid lump measuring 1.0 cm in diameter was detected in the anal verge. Under a diagnosis of a thrombosed external hemorrhoid, thrombectomy was performed under local anesthesia. One week after thrombectomy, the wound had not healed, and grayish-green tissue was seen at the bottom. A biopsy of the wound revealed atypical mononuclear cell infiltration. Myeloperoxidase and lysozyme were positive on immunohistochemical staining. Finally, the diagnosis of granulocytic sarcoma (GS) was made. Though it is well known that perianal complications occur quite often in patients with leukemia, it is unusual for a diagnosis of GS of the anus to be definitely established. To our knowledge, there has not been a previous report of GS presenting as a thrombosed external hemorrhoid. The development of GS should be considered during the management of such lesions, especially in patients with bone marrow disorders, such as acute myeloid leukemia (AML) or high-risk MDS.

急性膵炎における合併症として大腸穿孔をともなうことはまれである. われわれは急性膵炎が原因と考えられた横行結腸穿孔例を経験し手術によりこれを救命しえたので報告する. 症例は48歳の男性で, 発熱と全身倦怠感を認め検査のため入院となった. 腹部超音波検査, CT検査にて後腹膜膿瘍を疑い, 注腸造影検査を施行したところ横行結腸において腸管外への造影剤の漏出が認められたため, 後腹膜膿瘍および大腸穿孔と診断し緊急手術を行った. 開腹すると後腹膜は膨隆し切開にて多量の膿の排出を認め, 横行結腸に穿孔を認めた. 術式は横行結腸, 下行結腸切除と人工肛門造設ならびに後腹膜ドレナージを行った. 切除した大腸の穿孔部位の炎症所見は漿膜側において顕著で組織学的にpericolitisおよびmarginal arteryの血栓を認め, 急性膵炎による虚血性変化が大腸穿孔の原因と考えられた.
