A Case of Colon Cancer Coexisting with Colonic Tuberculosis and This Presented as Bowel Perforation / 대한소화기내시경학회지

Tuberculosis can involve any part of the body and there are case reports of tuberculosis coexisting with malignancy in most body organs. However, cases of intestinal tuberculosis associated with colon cancer have rarely reported. Inflammatory bowel diseases can progress to malignant diseases due to mucosal dysplastic change. Similarly, intestinal tuberculosis can cause chronic inflammation, but the exact relationship between intestinal tuberculosis and colon cancer is currently obscure. A 71-year-old woman visited our hospital because of abrupt right lower abdominal pain that progressed to rebound tenderness and abdominal rigidity. Abdominal computed tomography showed a polypoid mass in the cecum and a distended terminal ileum. Right hemicolectomy was performed and the surgical specimen revealed extremely well differentiated adenocarcinoma combined with intestinal tuberculosis and bowel perforation in the cecum. We report here on a rare case of colon cancer coexisting with colonic tuberculosis and this presented as bowel perforation. We also include a review of the relevant literature.

A Case of Pancreaticobiliary Duct Obstruction due to Pancreatic Tuberculosis Combined with a Colon Adenocarcinoma and Tuberculous Colitis / 대한소화기내시경학회지

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.

A Case of Diffuse Infiltrative Colon Cancer Coexisting with Colonic Tuberculosis / 대한소화기내시경학회지

Inflammatory bowel disease has a potential risk of developing colorectal cancer. However, there is little causal relationship between intestinal tuberculosis and colon cancer because intestinal tuberculosis is curable disease and has relatively short disease course. But there were a few case reports of intestinal tuberculosis associated with colon cancer. Diffuse infiltrating colon cancer, characterized by tumor cells in the presence of inflammatory changes with much fibrosis, is very rare in the colon. We experienced a 49-year-old woman who had tuberculous colitis combined with diffuse infiltrative colon cancer. She visited our hospital because of chronic diarrhea and abdominal pain. Colonoscopy showed multiple geographic ulcers in the transverse colon and partial intestinal obstruction. Histological examination revealed non-caseating granuloma and Mycobacterium tuberculosis was cultured in biopsied tissue. She took an anti-tuberculosis drug for 2 weeks, but her symptoms were aggravated. Therefore, extended right hemicolectomy was performed and revealed mucin-secreting, diffuse infiltrating adenocarcinoma. Herein, we report a rare case of diffuse infiltrative colon cancer coexisting with colonic tuberculosis with a review of liferatures.

Colon Cancer and Polyposis Associated with Colonic Tuberculosis

Tuberculosis can involve any part of the gastrointestinal tract but 80~90% of patients present the disease in the ileocecal region. The cases of colon cancer coexisting with colonic tuberculosis are relatively rare and ascending colon is the predominant site of the combined disease. A 46-year-old man, without specific past medical or family history, showed multiple colonic polyps and ulcers on colonoscopic examination. After surgery, the surgical specimen disclosed adenocarcinoma in the ascending colon, eleven adenomatous polyps throughout the colon, and multiple tuberculous ulcers in the entire colon. Tuberculosis of terminal ileum was also accompanied. The association of colonic tuberculosis and colon cancer with multiple polyps in this case may have been coincidental. The preoperative colonoscopic examination and pathologic diagnosis by frozen section during operation are necessary for the adequate treatment.

A Case of Colonic Tuberculosis Cured by Secondary Anti - Tuberculosis Medicine / 대한소화기내시경학회지

Tuberculosis is common disease in developing countries manifested by multi-organ involvement. Although the incidence of tuberculosis has been reducing recently due to the advancement of anti-tuberculosis chemotherapy, improvement of public health, and early diagnosis, the rate is still higher in developing countries. The diagnasis of colonic tubcrculosis is difficult due to its frequency, vague manifestation, and difficulty in confirming the disease process. Fortunately, the advent of flexible colonoscopy has provided an opportunity to confirm the diagnosis of colonic tuberculosis, however biopsy can frequently leveal false negative results. A-27-year-old man was admitted with a 2 week history of rectal bleeding. He complained of anorexia, abdominal pain, and weight loss. Routine laboratory tests and chest X-ray findings were within normal limits, with the exception of left pleural thickening. A colonoscopy showed irregular and small, multiple, and shallow polypoid mucosal lesions in the ascending colon and multiple ulcers in the transverse colon. Multiple colonic biopsies suggested tuberculosis. After three months of prirnary anti-tuberculosis medica tion, the patient showed slightly improved coiono- scopic findings. Follow-up colono- scopic findings revealed more aggrevation and chest X-ray findings showed multiple patch consolidation in the left lung field. Primary anti-tuberculosis medication was stopped and substituted for secondary anti-tuberculosis medication. When clinical and colonoscopic methods are found to be compatible with intestinal tuberculosis in countries with a high prevalence of colonic tuberculosis, a therapeutic trial with an antituberculosis agent is usually considered. In a failed therapeutic trial, considerations must be made not only to other inflammatory bowel diseases such as crohn's disease, but also to multi-drug resistance tuberculosis.

Endoscopic Findings of Colonic Tuberculosis / 대한소화기내시경학회지

The purpose of this paper is to review the colonoscopic fingings of twenty two patients with colonic tuberculosis which were diagnosed by colonoscopic finding, histopathology, and follow-up observation after antituberculosis chemotherapy at Pusan National University Hospital from January 1992 to December 1994. The results were as follows: 1) The male to female ratio was 1: 1.2, and the average age of the patients was 39.4 years with a slight predominance in women. The age of peak incidence was the 4th decade 40.9%). 2) Abdominal pain(95%), diarrhea(63%), and weight loss(50%) were the most common clinical findings. Others were constipation, melena, and palpable abdominal mass. The location of the pain was right lower abdomen, epigastrium, central abdomen, and left lower abdomen in decreasing order. 3) Hematologic findings showed decrease in hemoglobin level, increase in ESR, and positive CRP(61.5%). The white blood cell counts were mostly normal. 4) The stool examination showed positive occult blood in 7 cases among 18 cases (38.9%). Acid-fast bacteria was observed in stool of one case. 5) On colonoscopy, the lesion sites were ileoeecal valve(75%), ascending colon(72.7 %), terminal ileum(52.6%), cecum(42.9%), transverse colon(31.8%), descending colon (27.3%), sigmoid colon(9%), and rectum(9%) in decreasing order of frequency. Most of them involved ileocecal area. 6) On colonoscopy, the shape of ulcer revealed circular(41%), fusion(36%), and irregular pattern(18%). It found skipped area in 9 cases, pseudopolyp in 8 cases, patency of ileocecal valve in 5 cases, and severe deformity of ileocecal valve in 6 cases. 7) Microscopic finding of biopsy specimens revealed noncaseating granulomatous inflammation in 12 cases, and nonspecific ulcerative inflammation in 10 cases. In conclusion the diagnostic yield may be greatly enhanced by obtaining multiple target biopsies frorn tbe deep portion of the ulcer bed and margins. Judged from the colonoscopic finding and clinical improvement after antituberculosis chemotherapy, more accurate diagnosis can be acquired.
