1/7. Hamartomatous gastric polyposis in a patient with tuberous sclerosis.A 42-year-old female diagnosed with tuberous sclerosis was found to have multiple polyps in the fundus of stomach. On histologic examination, the lesions were hamartomatous polyps. In tuberous sclerosis, many lesions occur in multiple organs and there are several reports about the frequent association of hamartomatous polyps of the colon. However, gastric manifestation of tuberous sclerosis has not been established probably due to its asymptomatic nature. This is the first report of multiple gastric hamartomatous polyposis in patient with tuberous sclerosis.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/7. Malrotation of the bowel resulting in a left-sided caecal carcinoma presenting as a palpable intrahernial mass.An 86-year-old woman presented with a large left-sided intrahernial mass, which was shown on CT to represent an abnormally located caecal tumour. An underlying bowel malrotation was also found explaining the left-sided nature of the mass.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/7. Emergency helical CT scan in acute abdomen: a case of intestinal intussusception.Surgeons are familiar to the nosological entity "partial intestinal obstruction". intussusception constitutes a rare etiologic factor for this entity but usually remains undiagnosed preoperatively. Several imaging techniques have been proposed as useful in the diagnosis of intussusception but none of these has a remarkable sensitivity and specificity. In the following case of partial intestinal obstruction, we performed an helical CT scan of the abdomen. The method revealed with an excellent accuracy the nature (intussusception) and the location (ascending colon) of the partial intestinal obstruction. Having the extra advantage of the shorter examination time than the classical CT scan, we propose the helical CT as an alternative diagnostic modality for preoperative evaluation of patients with partial intestinal obstruction.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/7. Hypertrophic ileocaecal valve simulating a malignant tumour. A case report.A patient presented with rectal bleeding which, on investigation, was though to be due to a polyp within the caecum. The benign nature of the lesion could not be established conclusively without surgical exploration. A limited right hemicolectomy was performed and examination of the specimen revealed a prominent ileocaecal valve. The problem of diagnosing this entity pre-operatively is discussed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/7. Non occlusive ileocaecocolic intussusception caused by caecum cancer--case report.A case of ileocaecocolic intussusception caused by a caecum carcinoma is presented. The authors stress the peculiarity of clinical manifestation, without intestinal obstruction despite the presence of a big abdominal mass involving vessels and bowel, revealed by CT scanning and angiography. endoscopy was not able to identify the nature of the lesion. laparotomy performed with the idea to find a mesenchymal neoplasia, permitted to achieve the diagnosis.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/7. Malignant fibrous histiocytoma of the cecum: report of a case and review of the literature.Malignant fibrous histiocytoma (MFH) of the gastrointestinal tract is extremely rare. Here we report a case of MFH of the cecum and review other cases of large bowel MFH in the literature. A 64-year-old man had a large tumor mass in the cecum associated with multiple small peritoneal implants. Histologically, most of the lesion showed inflammatory pseudotumor-like appearance; that is, a mixed proliferation of fibroblasts and myofibroblasts loosely arranged in sweeping fascicles or whorled structures and an admixture of chronic inflammatory cell infiltrate. The myofibroblastic nature of the spindle-shaped cells was confirmed by their immunohistochemical and ultrastructural findings. In addition, there was atypical histiocytic cells infiltrate in some areas and marked lymphatic involvement and lymph node metastasis by such histiocytic cells. These features were interpreted as MFH, although it had to be distinguished from inflammatory fibrosarcoma and leiomyosarcoma. The differential diagnosis is discussed here.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/7. fruit pit obstruction. "The propitious pit.".Ingestion of fruit pit must be a frequent and innocuous phenomenon, judging from the expected frequency of such occurrences and the relative dearth of medical reports to the contrary. Reported here are four cases in which fruit pits of varied nature completed an otherwise incomplete intestinal obstruction. On of these was in the terminal ileum, with incomplete obstruction due to regional ileitis, in which the offending pit was seen radiologically but was not recognized as such. The other three were in the transverse colon, at the site of annular carcinomatous lesions. The completion of the obstruction by the fruit pits eventuated in earlier symptoms, diagnosis, and treatment. In one case, the fruit pits were multiple; in the remainder, they were single.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
