Abstract
The majority of colorectal and anal malignancies are adenocarcinomas and squamous cell cancers, respectively. Despite the predominance of these neoplasms in these locations, rare histiotypes of the colon, rectum, and anus do occur. These histotypes include but are not limited to lymphoma, melanoma, diffuse cavernous hemangioma, and sarcomas, such as leiomyosarcoma or Kaposi's sarcoma. These tumors often present challenges to clinicians with respect to diagnosis, staging, management, and pathology because of their unfamiliarity. A Medline search using "colon," "rectum,""anus," "lymphoma," "melanoma," "diffuse cavernous hemangioma," "squamous cell carcinoma," "carcinoid," "sarcoma," "leiomyosarcoma," "Kaposi's sarcoma," "Paget's disease," "Bowen's disease," and "basal cell carcinoma" as key words was performed as well as a cross-referencing of the bibliography cited in each work. Rare tumors of the colon, rectum, and anus present diagnostic and management dilemmas for clinicians. Because of their infrequency and poor prognosis, the optimal management of these tumors is controversial. For some histotypes, such as squamous cell carcinoma and carcinoids of the rectum, treatment depends on location and size of the tumor. For uncommon anal lesions, such as Bowen's disease, Paget's disease, and basal cell carcinoma, wide local excision (WLE) with negative margins is the standard of care. For other lesions such as anorectal melanoma or leiomyosarcoma, abdominal perineal resection versus WLE is still being debated. Because the optimal treatment of these tumors is still unclear, we recommend a multidisciplinary approach including a surgeon, primary care physician, medical oncologist, radiation oncologist, and pathologist to offer the patient the best outcome.

Abstract
AIMS The histological and immunohistochemical features of a congenital stromal tumour of the jejunum are compared with those of adult gastrointestinal stromal tumours (GIST). The literature concerning the diagnosis and prognosis of congenital small intestinal stromal tumours is reviewed. METHODS AND RESULTS A term female infant presented with intestinal obstruction, from birth. Histology of a 15-mm jejunal nodule showed a predominantly spindle-cell tumour with epithelioid areas. There was a low mitotic count and mild nuclear pleomorphism, extensive necrosis and haemorrhage, and focal calcification. Immunohistochemically, tumour cells stained for muscle specific actin and vimentin. Staining for CD117 (c-kit), S100, desmin and CD34 was negative. The features were compared to those of seven adult cases: no morphological feature was specific to the congenital tumour, which was smaller than the adult cases. There were no ultrastructural features specific for a particular line of differentiation. Immunohistochemical staining patterns were similar, except for CD117, which was strongly positive in all adult tumours, but negative in the congenital tumour. CONCLUSIONS This congenital jejunal stromal tumour morphologically resembled adult GIST, but lack of c-kit expression suggests that it is nosologically distinct. Despite the presence of histological features which would cause the tumour to be categorized as malignant in an adult, it is apparent from previous reports of congenital small intestinal stromal tumours that the prognosis is favourable.

Abstract
PURPOSE The aim of this study was to determine the outcome of patients with leiomyosarcoma of the rectum or anus treated with local excision and brachytherapy. METHODS Eight patients with leiomyosarcoma of the rectum (7 patients) or anus (1 patient) were treated with a transanal excision followed by a temporary iridium-192 interstitial implant to 4,500 cGy. Median tumor size was 4.2 (range, 1.5-5) cm. Margins were positive in six patients, negative in one patient, and close in one patient. RESULTS With a median follow-up of 53 months, median survival time was 53 months and the three-year actuarial survival rate was 71 percent. The cumulative incidence of failure as a component of failure for local was 25 percent (2/8), for abdominal was 0 percent (0/8), and for distant was 25 percent (2/8). Four patients eligible for functional analysis all had excellent sphincter function (1-2 bowel movements per day, no soilage). CONCLUSION In selected patients the use of conservative surgery followed by brachytherapy is a reasonable alternative to an abdominoperineal resection. However, more experience and longer follow-up are needed before this approach can be recommended routinely.

Abstract
Primary intestinal leiomyosarcomas in children are rare tumors. Twenty-seven previous cases are documented in the literature with little information available on the treatment, survival, and prognostic factors surrounding these tumors. The authors report the 28th case of pediatric intestinal leiomyosarcoma and its follow-up, that of a newborn presenting with intestinal obstruction. Follow-up from all previously reported cases is not recorded and is needed. Our patient, like most children with this tumor, underwent complete excision with no evidence of recurrence at 5 years. Visceral metastases from these neoplasms are atypical, and recorded long-term prognosis may be favorable, unlike their counterpart in the adult population.

Abstract
A 7-week-old boy presented with a 6-week history of failure to thrive, acute intestinal obstruction, and an apparently irreducible intussusception (noted on contrast enema). He underwent abdominal exploration, during which a cecal mass was identified and resected. The mass proved to be a leiomyosarcoma. Histologically, it was an intermediate-grade malignancy with a predicted 5-year survival rate of 16% to 23% based on data from the adult experience. Three years after resection and without having received adjuvant therapy, he is healthy and free of disease. A review of the literature showed that in infants these tumors are predominantly colonic, compared with the predilection for small intestinal lesions found in the older pediatric and adult populations. Infantile intestinal leiomyosarcomata are rare malignancies that do well if complete surgical excision of the disease can be accomplished. The histological prognostic indicators proposed for intestinal leiomyosarcomas in the adult population cannot be extrapolated to infants because when they occur in infants, they appear to be less aggressive, and these patients do well without adjuvant therapy.

Abstract
A case of an adolescent girl with metastatic gastric stromal tumor is described. There were three metastatic nodules in the liver at the time of the admission. A subtotal gastrectomy was performed. The tumor had distinctly nodular appearance and was composed of a variety of cells suggestive of smooth muscle differentiation. Electron microscopy revealed cytoplasmic neural processes and densecore neurosecretory granules. Immunohistochemistry showed positive neuron-specific enolase, synaptophysin, and chromogranin A in some of the tumor cells. Similar findings in the primary tumor and its liver metastases indicated a primitive neural differentiation and enabled us to classify the lesion as a gastric autonomic nerve tumor. No other tumors that would suggest that the gastric lesion is a part of Carney's triad were detected. The child was treated with chemotherapy but the liver metastases did not change significantly. She is alive with unresectable liver metastases 10 months after the gastrectomy.

Abstract
Intestinal leiomyosarcoma is a rare tumor in infants and children; only 46 cases have been reported in the English literature. Presenting signs and symptoms include abdominal pain and gastrointestinal obstruction and bleeding. We describe a neonate with the unique presentation of ileocecal intussusception accompanying an ileal leiomyosarcoma. In contrast to adult patients, where intussusception is associated with smooth muscle tumors in 30% of cases, leiomyosarcoma and subsequent intussusception is rare in infancy and childhood. The overall prognosis for long-term survival is similar for both pediatric and adult patients with leiomyosarcoma of the intestinal tract, with a five-year survival in reported cases of 53% and 40%, respectively.

Abstract
A 5-month-old white boy infant exhibited remarkable growth retardation and subsequently developed ileal obstruction, which was found to be due to solitary intestinal fibromatosis. This rare lesion has an excellent prognosis if it is completely excised. This is in contrast to cases of congenital fibromatosis with multiple lesions, which carries a poor prognosis.

Abstract
Leiomyosarcomas of the large intestine are unusual neoplasms, comprising less than 0.1% of all malignancies of the colon and rectum. Six cases of leiomyosarcoma of the anus have been reported. The optimal treatment for this neoplasm is not known. The standard surgical approach is abdominoperineal resection. The authors report the seventh case of this rare neoplasm and outline its treatment using local excision and iridium 192 brachytherapy in an attempt to preserve the anal sphincter. In selected patients, conservative surgery followed by radiation therapy may be an alternative to radical surgery, with the goals of local control of the disease and anal sphincter preservation. However, more experience is needed before this approach could be recommended routinely.

Abstract
A 78 year old woman with a rectal leiomyosarcoma is presented. The case is of interest because of very unusual radiological and operative features of a large rectal diverticulum. As a result of the difficulty in making the correct diagnosis pre- or intraoperatively, a simple, but possibly suboptimal, resection was performed. Although the patient has done well, the long-term outlook is uncertain. The problems of optimum management and prediction of outcome in this uncommon condition are discussed.

Abstract
Leiomyosarcoma of the rectum is rare. The standard treatment is abdominoperineal resection and, in the past, radiation therapy has been employed in the palliative setting only. The authors report two additional cases of this rare tumor and its treatment using sphincter-preserving surgery and radiation therapy. In selected patients, conservative surgery followed by radiation therapy (brachytherapy with or without external beam radiation) may be an alternative to radical surgery with the goals of local control of the disease and rectal sphincter preservation. However, more experience and longer follow-up are needed before this approach could be recommended routinely.

Abstract
A rare case of a newborn infant with leiomyosarcoma of the transverse colon is reported. The condition was associated with meconium peritonitis due to a perforation proximal to a portion of the transverse colon that was completely surrounded by the tumor. The 12 previously published cases of leiomyosarcoma of the colorectum in childhood are reviewed, and the pathogenesis of meconium peritonitis is discussed.

Abstract
Primary intestinal leiomyosarcomas in children are unusual tumors with little known about their natural history. Two patients (aged 9 and 10 years) with leiomyosarcoma of the jejunum treated at our institution are reported and added to the 20 other patients reported in the literature. The first patient had a grade 1 leiomyosarcoma completely resected, received no additional therapy, and remains alive with no evidence of disease 14 years later. The second patient presented with a perforated grade 2 leiomyosarcoma which was incompletely resected; he received combination chemotherapy with an initial good response, but eventually died from sarcomatosis 7 years after initial diagnosis. The 22 cases of pediatric intestinal leiomyosarcoma presented more commonly with obstruction or perforation, were able to be completely resected more often, and appear to have a better prognosis than in adults. Thus, intestinal leiomyosarcomas in children appear to have a natural history different from that of the same tumor arising in adults.
