Abstract
Although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, nonneoplastic reactive processes may involve the gastrointestinal tract and mesentery, causing diagnostic confusion with more aggressive neoplasms, such as fibromatosis or gastrointestinal stromal tumors. In this study, we report a series of fibroinflammatory lesions of the gastrointestinal tract that we think represent a relatively cohesive group of tumors and describe the clinical and pathologic features of this entity, which we have termed "reactive nodular fibrous pseudotumor." The tumors affected five patients (four male and one female patient) who ranged in age from 48 to 71 years (mean 56 years). Two patients presented with acute abdominal pain without a significant past medical history, two had incidental lesions discovered during evaluation for other medical conditions, and one was found to have an abdominal mass. Three patients had a history of abdominal surgery. The tumors were multiple in three patients and solitary in two patients. In four cases, at least one of the tumors involved the small intestine or colon, and the lesion was confined to the peripancreatic soft tissue in one case. The tumors were firm, tan-white, ranged in size from 4.3 to 6.5 cm in greatest dimension, and were grossly well circumscribed. All of the lesions were of low to moderate cellularity and composed of stellate or spindled fibroblasts arranged haphazardly or in intersecting fascicles. Three cases had microscopically infiltrative borders. The stroma was rich in collagen, which was wire-like, keloidal, or hyalinized. Intralesional mononuclear cells were sparse but were more numerous peripherally and frequently arranged in lymphoid aggregates. Immunohistochemical stains demonstrated that all of the tumors stained for vimentin, 80% stained for CD117 or muscle specific actin, 60% stained for smooth muscle actin or desmin, and none of the tumors stained for CD34, S-100 protein, or anaplastic lymphoma kinase-1. Follow-up information was available in all cases: four patients had no residual disease following surgical resection (mean follow-up 16.3 months) and one patient who had an incomplete surgical resection had stable disease at 26 months. In summary, we report a series of distinct intraabdominal fibroinflammatory pseudotumors that we have collectively termed "reactive nodular fibrous pseudotumors." These lesions are uncommon and may infiltrate the bowel wall, thereby mimicking primary bowel neoplasms or intraabdominal fibromatosis. Recognition of these nonneoplastic lesions is important, as they pursue a benign clinical course, but may be confused with other mesenchymal neoplasms that require more aggressive treatment.

Abstract
We reviewed 84 cases coded as mesenteric lipodystrophy (ML), mesenteric panniculitis (MP), or retractile mesenteritis and sclerosing mesenteritis (SM), grading fibrosis, inflammation, and fat necrosis, and evaluating clinical subgroups. There was no gender or racial predominance. Patient age range was 23-87 years (average 60). Patients most often presented with abdominal pain or a palpable mass. A history of trauma or surgery was present in four of 84 patients. The most common site of involvement was the small bowel mesentery as a single mass (58 of 84) with an average size of 10 cm, multiple masses (15 of 84), or diffuse mesenteric thickening (11 of 84). All patients had some degree of fibrosis, chronic inflammation, and fat necrosis. Although a few patients showed a sufficient prominence of fibrosis, inflammation, or fat necrosis to permit a separation into SM, MP, or ML, respectively, in most patients these three components were too mixed for a clear separation. The clinical, demographic, and gross features did not help in defining these three entities. Contributors diagnosed 12 as sarcoma. Of 39 patients followed beyond the postoperative period, none died of these lesions. We conclude that SM, MP, and ML appear to represent histologic variants of one clinical entity, and in most cases "sclerosing mesenteritis" is the most appropriate diagnostic term.

Abstract
A patient suffering from Weber-Christian panniculitis was found at necropsy to have similar lesions in the visceral adipose tissue. When the lesions occur internally, diagnosis during life is complicated by the difficulty of examining visceral adipose tissue and the disease may often go unrecognized, but patients suffering from Weber-Christian panniculitis should be investigated bearing in mind the possibility of internal lesions. Only 11 cases confirmed by necropsy appear to have been reported hitherto. The aetiology remains obscure. It is suggested that the name ;systemic Weber-Christian disease' be applied when the lesions occur in adipose tissue other than the panniculus adiposus and that the term ;Weber-Christian panniculitis' be used when the lesions are confined to the subcutaneous adipose tissue.

Abstract
Primary mesenteritis is a rare disease. Two cases and two additional patients with mesenteric fibrosis/fibromatosis are reported. A classification of primary and secondary mesenteritis is suggested in order to replace the confusing variety of terms used for the same disease process. Differential diagnosis of mesenteric fibrosis versus mesenteric fibromatosis may be difficult, and some criteria for the separation of these two entities are discussed. Among the clinical symptoms, transmission of aortic pulsations to the anterior abdominal wall is a rare but important aid for diagnosis. Associated diseases are malignant lymphoma, colonic adenomatosis (Gardner's syndrome) and retroperitoneal fibrosis. Microscopically, mesenteric lipomatosis and Whipple's disease must be ruled out. Usually, surgical treatment is not necessary. Prednisone and azathioprine may be helpful in severe cases. Fatal outcome of primary mesenteritis is extremely rare.

Abstract
A case of nodular mesenteritis simulating a carcinoma of the sigmoid is presented. The unusual features of the case are analyzed. Emphasis is placed on the basic histologic reactions seen in nodular mesenteritis and on their possible implications. The questionable relationship to Weber-Christian disease is discussed.

Abstract
Abstract
A second case of bilateral ureteric obstruction owing to diffuse pelvic lipomatosis is reported. The clinical features and possible aetiological factors are discussed. The condition may be mistaken for a pelvic neoplasm due to high fixation of the bladder and colon, but it is felt that the diagnosis can be made on the basis of characteristic radiological findings. Surgical intervention is unsuccessful in replacing the bladder and colon to their normal positions but may be necessary for relief of obstruction.
