1/88. carcinoma of the colon in children: a report of six new cases and a review of the literature.Of six children with carcinoma of the colon, none had ulcerative colitis or a family history of carcinoma of the colon or colonic polyposis. In 75 cases traced in the literature, a common early symptom of carcinoma of the colon in children is acute, crampy abdominal pain. At laparotomy for suspected appendictis, the possibility of the acute pain being due to carcinoma of the colon should be borne in mind. Otherwise the symptoms of carcinoma of the colon in children do not differ substantially from those in adults. The prognosis is unfavorable; in only 2.5% of the cases on record did the children survive 5 yr after the operation.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
2/88. Endoscopic features of intestinal smooth muscle tumor in a child with AIDS.Intestinal leiomyosarcomas are exceedingly rare in immunologically intact children, except during infancy. While leiomyosarcomas account for less than 2% of all soft tissue tumors in childhood, they are the second most frequent malignancy in children with the acquired immunodeficiency syndrome (AIDS). In this cohort they are often located in unusual sites for primary soft tissue tumors. This report describes a young girl with advanced AIDS, referred for evaluation of abdominal pain, hematochezia, and wasting syndrome. colonoscopy revealed two 1- to 2-cm submucosal nodules with central umbilication. Repeat colonoscopy 18 months later revealed no changes in these lesions. biopsy revealed a submucosal spindle-cell lesion, with necrosis and cellular atypia. Initially it was characterized as a partially excised low-grade leiomyosarcoma. However, the final consensus diagnosis was smooth muscle tumor of uncertain malignant potential. Because of her advanced AIDS, there was no attempt at surgical resection or chemotherapy. Thirty-six months after initial referral, she remains alive without radiographic or clinical evidence of local extension or metastases. Additional data are required to determine the long-term outcome of these indolent submucosal tumors in the digestive tracts of children with AIDS.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
3/88. Mast cell sarcoma with tissue eosinophilia arising in the ascending colon.Mast cell sarcoma is a rare disease. We report an unusual case of this neoplasm arising in the ascending colon of a 32-year-old Japanese woman who presented with abdominal pain. An ulcerating mass in the colon was resected, along with enlarged mesenteric lymph nodes. Two years after surgery, the neoplasm recurred as left cervical lymphadenopathy and an intra-abdominal mass. Despite predonine and radiation therapy, the disease progressed, and the patient died. The tumor cells had abundant fine granular or clear cytoplasm, and oval, lobulated, or indented nuclei. Numerous mature eosinophils were intermingled with the tumor cells. Immunohistologic studies on paraffin sections demonstrated that the majority of the tumor cells were strongly positive for CD45RB, CD68, and mast cell tryptase. They were unreactive, however, with a broad spectrum of antibodies against myelomonocytic and lymphocytic antigens. The mast cell nature of this rare type of tumor can be best identifiable by immunostains for mast cell tryptase.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
4/88. Continuous inferior mesenteric ganglion block for the control of abdominal pain.BACKGROUND AND OBJECTIVES: A 71-year-old woman was referred for control of intractable left-sided abdominal pain and constipation caused by stage 2B rectosigmoid colon cancer. She was treated with an intravenous morphine sulfate infusion at 4 mg/h which made her drowsy and lethargic. Because the distal colon is innervated by the inferior mesenteric sympathetic ganglion, it was hypothesized that a continuous block of this ganglion would provide both pain control and increased intestinal motility. methods: The patient was placed in a prone position, and a Tuohy needle was placed at an entry site 7 cm lateral to the L3 spinous process. The needle was advanced 2 cm anterior to the L3 vertebral body with fluoroscopic guidance. An 18-gauge indwelling catheter was placed through the needle and a continuous infusion with 0.1% bupivacaine was maintained for 4 days. RESULTS: The patient obtained immediate pain relief and bowel motility. She remained awake and comfortable throughout the duration of therapy. She was discharged home 3 days after stopping the infusion and required a minimal amount of opioids. CONCLUSION: Continuous inferior mesenteric ganglion block may be an option in providing relief for pain caused by distal colon pathology.- - - - - - - - - - ranking = 5keywords = abdominal pain (Clic here for more details about this article) |
5/88. Sigmoid colon carcinoma metastatic to the myometrium.Metastases to the uterus from extragenital cancers are significantly rarer than metastases to the ovaries. Of the approximately 200 cases of metastases to the uterus from extragenital cancers that have been reported in the literature, more than half are cases of metastases from breast carcinoma and only 16 are cases of metastases from colorectal carcinoma. A case of isolated metastases restricted to the myometrium of the right uterine comu from sigmoid colon carcinoma, without involvement of the ovaries, is described. The patient who six months previously had surgery for sigmoid colon carcinoma presented with right lower abdominal pain and a palpable mass in the region of the right uterine cornu. The diagnosis of isolated metastases restricted to the myometrium of the right uterine cornu was confirmed by total abdominal hysterectomy and bilateral salpingo-oophorectomy. This case illustrates that a growing uterine mass in a patient with a history of primary extragenital cancer, regardless of whether abnormal uterine bleeding is present or absent, should alert the physician to consider the possibility of uterine metastases.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
6/88. angiolipoma of the colon with right lower quadrant abdominal pain.BACKGROUND/AIM: An angiolipoma is a common benign neoplasm with a characteristic vascular component that occurs in the subcutaneous tissue and rarely in the gastrointestinal tract. We report on a 69-year-old man with a submucosal angiolipoma in the cecum. methods: This patient was treated with a laparoscopy-assisted ileocecostomy, and a side-to-side anastomosis was performed extracorporeally. RESULTS: A light microscopic study supported the diagnosis of an angiolipoma of the colon. After 5 years of follow-up, the patient has no symptoms or signs of recurrence. CONCLUSION: The colonic angiolipoma was successfully removed using a minimally invasive laparoscopic technique. copyright copyright 1999 S.

7/88. Colonic carcinoma: a case report in a child and review literature.This article reports one case of child colonic carcinoma. This is a rare disease in children which usually occurs in predisposing conditions, e.g. ulcerative colitis, familial polyposis coli, Gardner's syndrome, Turcot's syndrome and Peutz-Jegher's syndrome. The patient in this report was 12 years old. He presented with chronic intermittent colicky abdominal pain and uncorrectable iron deficiency anemia for 7 months prior to definite diagnosis. This report also reviews the literature about colorectal carcinoma in children. physicians can make an early diagnosis with a high index of suspicion if they cannot explain clearly what causes abdominal pain. Further investigations should be performed, thereby, avoiding delayed diagnosis and improving survival rate.- - - - - - - - - - ranking = 2keywords = abdominal pain (Clic here for more details about this article) |
8/88. Colon cancer in pregnancy: report of a case and review of the literature.Most colon cancer cases occur in patients over 50 years of age, although about 3% of colorectal cancer patients are younger than 40. During pregnancy the incidence of this neoplasm is estimated to be 0.002%. To date only 32 cases of colonic cancer arising above the peritoneal reflection during pregnancy have been described in the literature. We report another such case, stressing the need for constant alertness on the part of physicians in the presence of abdominal pain and/or distension, a palpable abdominal mass, rectal bleeding and/or weight loss during pregnancy. In fact, the reportedly poorer prognosis of this cancer in pregnant patients is mainly due to the fact that the initial symptoms of the malignancy are usually attributed by the patient, but also by physicians, to normal pregnancy.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
9/88. lymphangioma of the colon: a case report and review of the Japanese literature.Intraabdominal lymphangiomas are rare, although these lesions can occur in the mesentery, omentum, retroperitoneum, or gastrointestinal tract wall. Here we report a case of lymphangioma of the transverse colon and review the other cases reported in the Japanese literature. Our patient presented with lower abdominal pain and barium enema revealed a filling defect in the transverse colon. colonoscopy disclosed a submucosal tumor, which changed shape with alteration the patient's position and showed the cushion sign. This lesion was covered with normal-looking mucosa. A correct diagnosis was made from these findings. knowledge of these endoscopic features may help physicians to provide appropriate diagnosis and treatment of colonic lymphangioma.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
10/88. Endosonographic probe-guided endoscopic removal of colonic pedunculated leiomyoma.We report a rare case of endoscopic removal of colonic pedunculated leiomyoma with an aid of endoscopic ultrasonography (EUS). A 46-year-old man was admitted to our hospital with complaints of lower abdominal pain and alternating constipation and diarrhea. colonoscopy revealed a small pedunculated polyp in the transverse colon covered with almost normal mucosa. EUS showed a hypoechoic solid tumor with clear margins and smooth contour in the second to third layer. We considered this lesion as a submucosal tumor of the colon with no continuity to the muscularis propria. We performed endoscopic removal of this tumor successfully, and histological diagnosis was a leiomyoma. Endoscopic removal of colonic pedunculated leiomyoma is rare. Moreover, in our case, EUS showed typical findings of colonic leiomyoma and was useful to assess the location of the submucosal tumor. We describe herein our experience and discuss similar cases reported in the English literature.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
