1/12. Intraluminal implantation of rectal carcinoma successfully resected by endoscopy.A 55-year-old Japanese woman presented at our hospital complaining of hematochezia 4 months after surgery for a rectal carcinoma. A proctoscopy revealed 2 protuberant lesions in the rectum, 5 mm anally from the anastomotic suture line. The diagnosis of adenocarcinoma was confirmed by biopsy. It was considered that these lesions were caused by intraluminal implantation from the primary rectal carcinoma. The patient underwent an endoscopic resection for these recurrent lesions and has remained stable, with neither recurrence nor metastasis, in the 7 years since the resection. For rectal carcinoma, we propose early follow-up by proctoscopy, namely within 4 months after surgery.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
2/12. Metastatic renal cell carcinoma involving the rectum.BACKGROUND AND AIMS: Metastatic spread of a distant tumor to the rectum is extremely rare. To our knowledge, there have been no published reports of hematogenic metastasis from a renal cell carcinoma to the rectum. patients AND methods: A patient with a renal cell carcinoma was initially treated by a radical right nephrectomy. RESULTS: Nine months after the surgery he started to have multiple episodes of hematochezia. colonoscopy showed a nodular lesion located in the distal rectum, and biopsy revealed an undifferentiated carcinoma. The patient then underwent abdominoperineal resection of the rectum, and histological examination showed metastatic renal clear cell carcinoma. CONCLUSION: This case represents an exceedingly rare condition, which has never been reported before.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
3/12. Primary adenosquamous and squamous cell carcinoma of the colon and rectum.Three new cases of squamous cell and adenosquamous carcinoma of the rectum are reported, bringing the total number of cases in the English medical literature to 72. Each of the three patients presented with painless hematochezia. Therapy was by surgical resection followed by chemoradiation therapy in two patients. The incidence, presentation, diagnostic criteria and methods, tumor location, natural history, theory of etiology and management of this unusual tumor are discussed.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |

5/12. Regression of rectal mucosa-associated lymphoid tissue lymphoma but persistence of helicobacter pylori infection of gastric mucosa after administration of levofloxacin: report of a case.PURPOSE: Several articles have reported regression of rectal lymphoma of mucosa-associated lymphoid tissue after anti- helicobacter pylori therapy. It remains unclear, however, whether lymphoma of rectal mucosa-associated lymphoid tissue is related to helicobacter pylori infection. methods: A 60-year-old woman visited our hospital with a complaint of hematochezia. On colonoscopy a pale, ulcerated protrusion approximately 3.5 cm in diameter was found in the rectum. Pathologic diagnosis of a biopsy specimen was low-grade mucosa-associated lymphoid tissue lymphoma. The patient received a ten-day course of levofloxacin, and the cycle was repeated three times over seven months. RESULTS: Although persistence of helicobacter pylori infection was confirmed, the tumor regressed completely. CONCLUSION: Our findings in this case suggest that rectal lymphoma of mucosa-associated lymphoid tissue may be related to unknown microorganisms other than helicobacter pylori. levofloxacin may be effective for treatment of rectal lymphoma of mucosa-associated lymphoid tissue regardless of helicobacter pylori infection.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
6/12. An unusual rectosigmoid mass: endometrioid adenocarcinoma arising in colonic endometriosis: case report and literature review.Malignant transformation is an infrequent complication of endometriosis. The ovary is the primary site in 79 per cent of cases, and extragonadal sites are identified in 21 per cent. Primary involvement of these types of tumors with the colon and/or rectum is a rare clinical entity. Endometrioid carcinoma is a common histologic type that remains a diagnostic challenge-the main differential diagnosis includes colorectal carcinomas. We report a case of malignant transformation arising in colonic endometriosis. The patient had a total abdominal hysterectomy and bilateral salpingo-oophorectomy 10 years before she presented with hematochezia. The patient was ultimately treated by surgical resection. Immunohistochemical staining in addition to the usual histopathology was critical for accurate diagnosis of this endometriosis-associated intestinal tumor.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
7/12. life-threatening hematochezia from a rectosigmoid vascular malformation in Klippel-Trenaunay syndrome: long-term palliation using an argon laser.Recurrent severe hemorrhage from intestinal vascular malformations, although extremely rare, may be associated with significant morbidity and mortality. The treatment may require extensive surgical resection, vascular embolization, and repeated blood transfusions. An adolescent boy with the Klippel-Trenaunay syndrome involving the pelvis and left leg presented with recurrent life-threatening hematochezia associated with defecation. endoscopy documented that the bleeding originated from the submucosal venous angiomata in the region of the hemorrhoidal plexus. An argon laser was used to systematically coagulate the venous angiomata involving the distal 7 cm of the anorectal canal. Postoperative minor rectal bleeding and rectal tenesmus resolved in a few days. The patient has had only one brief episode of hematochezia in more than 4 years of follow-up. The use of the argon laser has provided effective palliation of colorectal vascular malformations with minimal morbidity but more importantly has allowed the preservation of normal anorectal function.- - - - - - - - - - ranking = 6keywords = hematochezia (Clic here for more details about this article) |
8/12. Cyclical rectal bleeding in colorectal endometriosis.Three case reports of cyclical rectal bleeding in endometriosis affecting rectum and sigmoid colon emphasize the close relationship between such cyclical bleeding and intestinal endometriosis. The cause of bleeding, however, is still unclear. The predilection of endometriotic deposits for the outer layers of the bowel wall suggests that mucosal involvement is not a prerequisite for rectal bleeding. The frequent absence of identifiable intramural haemorrhage casts doubt on the premise that intestinal endometriotic deposits 'menstruate'. The cause may simply be a transient tear in normal mucosa due to swelling of an underlying endometriotic deposit at the time of menstruation.- - - - - - - - - - ranking = 0.0061947883158735keywords = haemorrhage (Clic here for more details about this article) |
9/12. Inflammatory cloacogenic polyp in a child: part of the spectrum of solitary rectal ulcer syndrome.A 15-year-old boy with Marshall-Smith syndrome presented with increased frequency and urgency of stooling, hematochezia, and rectal pain. A polypoid mass was found at the anorectal junction and excised. Microscopically, the lesion was covered by both squamous and columnar mucosa. It was villiform in configuration with focal ulceration and strands of smooth muscle in the lamina propria. These features are characteristic of an inflammatory cloacogenic polyp, a lesion not previously reported in the pediatric age group. Inflammatory cloacogenic polyp is related to solitary rectal ulcer syndrome and is most likely due to prolapse of the anorectal transition zone. Although rare in this age group, solitary rectal ulcer and its variants should be considered in the differential diagnosis of anorectal and rectal lesions in the pediatric patient.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
10/12. Case report of primary squamous carcinoma of the rectum.PURPOSE: To report a patient with primary squamous carcinoma of the rectum. CASE REPORT: A 40-year-old woman with hematochezia and change in bowel habits was studied. The main laboratory finding was a mild anemia. A barium enema and a proctoscopy revealed a rectal neoplasm at eight cm from the anal verge. A transendoscopic biopsy demonstrated an squamous rectal carcinoma. A transrectal ultrasound and CT scan of the abdomen revealed a big rectal mass with transmural affection and possible involvement of the lymph nodes. The carcinoembriogenic antigen (CEA) was high (32 ng/mL). The patient underwent radiotherapy with 46 Gy, and 5-fluorouracil as radiosensitizer. Three months later, a new CT scan showed significant reduction of the size of the mass, and the patient underwent a very low anterior resection with double-stapled anastomosis. The analysis of the specimen showed a squamous carcinoma of the mid-rectum, invading through the wall without lymph node affection and with proximal, distal, and radial margins free of tumor. The CEA returned to normal after surgery (1.3 ng/mL). The patients is alive and without evidence of disease 18 months after the operation. CONCLUSION: Primary squamous carcinoma of the rectum is a rare disease, and surgery seems to be a good option of treatment, with the possibility of sphincter preservation depending upon the location of the tumor.- - - - - - - - - - ranking = 1keywords = hematochezia (Clic here for more details about this article) |
