Intestinal lymphangiectasia and colonic polyps: surgical intervention.

A 36-mo-old boy with Milroy's Disease, intestinal lymphangiectasia, and an exudative enteropathy (EE), was shown to have four colonic polyps. A large adenomatous polyp was excised from the transverse colon in an effort to control his EE and hypoalbuminemia (1.95 g/dl). His clinical status then stabilized until age 50 mo when there was a marked exacerbation of his EE. Medical management resulted in a temporary stabilization of his condition. A partial resection (40 cm) of the visually worse affected jejunum was performed. There was no improvement in the EE as measured by 51Cr-tagged albumin study; however, his clinical response was dramatic. In the 10 mo since surgery, he has been well and has shown catchup in linear growth.

[A case of umbilical polyp with aberrant pancreas and small intestinal mucosa--analysis of cases of umbilical polyp reported in Japan].

We report a case of a 60 year-old man with an umbilical polyp composed of the aberrant pancreas and small intestinal mucosa. This is an extremely rare lesion which originates in remnants of omphalomesenteric duct and is usually diagnosed in the infant period. Microscopic examination disclosed the aberrant pancreas with exocrine glands and ducts, but no islets of Langerhans. The above findings suggested that the pancreas might have been HEINRICH II in type.

Symptomatic inflammatory fibroid polyp of the small bowel: report of two cases with review of literature.

Two cases of symptomatic inflammatory fibroid polyps (IFP) of the small intestine are presented, and the 17 adequately described symptomatic IFP previously reported are reviewed. IFP of the small bowel are rare. Most patients present with intestinal obstruction and a few with chronic anemia. IFP have characteristic histologic features and are easily recognized if they are considered in differential diagnosis.

[Diagnosis and treatment of villous polyps of the large intestine and rectum].

The work is based on the examination of 67 patients with villous tumors of the colon and rectum. The peculiar features of the clinical course have been studied, and the efficacy of different diagnostic measures have been analysed. In the diagnosis of villous tumors great importance is attached to endoscopy in the complex of clinical examination of a patient. Roentgenological investigation with the use of the accessory technics--double contrasting, laterography, "angular" roentgenography seem to be an important step in the investigation. Only after the histological study is completed, one can ultimately judge the fact of the polyp malignification. The classification of villous polyps of the colon and rectum based on the histological principle is suggested. The results of the treatment are analysed, and some practical recommendations are given.

[The morphogenesis of polyps of the large intestine].

The proportion of so-called hyperplastic polyps among other colon epithelial tumours remains unclear. Colon polyps are studied in 400 patients: hyperplastic polyps are found in 107, a combination of hyperplastic polyp with tubular adenoma in 143, tubular adenoma in 72, villous adenoma in 41 and tubulovillous adenoma in 37 cases. Hyperplastic structures and formation of adenomatous structures were, as a rule, observed in a polyp tip, this corresponding to the increase of nuclei volume and DNA amount in the tip colonocytes. The determination of karyometric coefficient (the ratio of the colonocyte nuclei volume in the polyp tip to colonocytes in the intact mucosa) is proposed as a quantitative criterion of proliferative and dysplastic processes.

Distribution and significance of the smooth muscle component in polyps of the large intestine.

Immunocytochemical staining for alpha smooth muscle actin specifically reveals the distribution of the muscularis mucosae and pericryptal intramucosal smooth muscle fibers in the normal mucosa and polyps of the large intestine. In the latter, the muscular component is hyperplastic, especially in pedunculated polyps, which display a thick "muscular zone" at the top of the stalk. The diagnostic (and prognostic) significance of the distribution pattern of the muscular component in polyps, and in "early invasion" cases, is discussed.

Polyps of the large intestine in Aarhus, Denmark. An autopsy study.

In 336 consecutive autopsies a total of 305 tumors were recorded in the large intestine. Of these, 184 were adenomas occurring in 26% of the 196 men and 17% of the 140 women, resulting in an overall prevalence of 22%, or 15% when standardized to the world standard population (WSP). The prevalence of adenomas increased with age, and a shift from distal to proximal location occurred in the older age groups, mostly accounted for by the greater tendency to multiplicity in old age. Regardless of age 57% of the cases of adenomas could have been identified by flexible sigmoidoscopy. The prevalence of hyperplastic polyps was 13%, and an association between these and adenomas was found. Five adenocarcinomas occurred in the study. With some exceptions, which are discussed in detail, the results are in accordance with studies from other countries with a high incidence of colorectal cancer and similar socioeconomic composition. The study supports the theory of the adenoma-carcinoma sequence.

Inflammatory fibroid polyp of the small intestine: ultrastructural and immunohistochemical observations.

The ultrastructural and immunohistochemical features of a primary tumor of the ileum showing the classic histologic features of an inflammatory fibroid polyp (IFP) of the gastrointestinal tract are presented. Ultrastructurally the proliferating cells showed a combination of fibroblastic and histiocytic features, with abundant rough endoplasmic reticulum and active production of collagen in many of the cells and long, dendritic cytoplasmic projections with large cytoplasmic vacuoles containing remnants of phagocytosed cellular debris in others. Immunohistochemical studies showed strong cytoplasmic positivity in the proliferating cells with vimentin antibodies and scattered positivity with muramidase. Additional findings include the ultrastructural demonstration of oligocilia and occasional primitive intercellular junctions. The findings in this case suggest that IFP may represent a proliferation of primitive submucosal stromal cells exhibiting incomplete fibrohistiocytic differentiation.

Inflammatory fibrous polyp (pseudotumor) of ileum, a rare cause of intestinal obstruction.

Inflammatory fibrous polyp of the ileum is a rare condition. This report adds one patient to the 11 previously reported. These lesions usually involve intermittent, colicky abdominal pain, often of several weeks duration and occasionally as a cause of acute intestinal obstruction. X-rays usually show small bowel obstruction or intussusception, but may be completely normal. The pathological diagnosis is seldom made before microscopic examination of resected specimens. They are clinically interpreted to be neoplasm and treated by segmental resection. No recurrences have been reported after treatment. Etiology is unknown.

Combined endoscopic and surgical treatment for multiple polyps of the small intestine in Peutz-Jeghers syndrome: a case report.

Combined endoscopic and surgical treatment in a 14-year-old girl with Peutz-Jeghers syndrome is reported herein. The patient was diagnosed with Peutz-Jeghers syndrome because of mucocutaneous pigmentation and hamartomas of the small intestine at 10 years of age, when she underwent an emergency laparotomy for an intussusception of the small intestine. Since this diagnosis, she has undergone follow-up, and barium radiologic and endoscopic studies have shown multiple polyps of various sizes from the stomach throughout the small intestine and to the colon. This time, with the use of combined endoscopic and surgical treatment for polyps of the small intestine, 26 polyps were removed endoscopically by performing only one enterotomy. This combined technique may allow for a longer interval between laparotomies, therefore reducing the complications associated with multiple laparotomies and resections.

Giant hyperplastic polyposis of the colon.

A patient with multiple large hyperplastic (metaplastic) polyps of the colon is reported. Hundreds of polyps, some over 3 cm in size, were distributed uniformly throughout the large bowel. There was no evidence of polyps in the stomach or small intestine. The polyps, except for their large size, had the histologic features of hyperplastic polyps. This condition can be clinically confused with adenomatous polyposis coli.

[Clinical manifestations of polyposis and polyps of the large intestine and "risk groups"].

In processing of 1603 clinical observations, studied dynamically during 15 years, using the multifactor analysis of clinico-morphological, roentgenological and statistic parallels, there were registered 156 different possible variants in a combination of the forms and clinical manifestations of polyposis and polyps of the colon. The degree of the malignant transformation risk for various forms of polyposis and polyps of the colon is extremely variable.
