Lipoma of the adrenal gland is extremely rare. This condition was first described in 1988 and only seven cases have been reported to date. We have experienced a case of adrenal lipoma which was thought to be adrenal myelolipoma on computed tomography (CT). A 56-year-old man was admitted to our department with a complaint of left abdominal pain. Sonography revealed a hyperechoic mass above the left kidney, and a CT scan revealed the mass to be comprised sharply marginated and an inhomogeneous structure. The tumor was comprised of areas of different density including a fatty tissue portion. These findings were strongly suggestive of adrenal myelolipoma or liposarcoma, and a left adrenalectomy was performed. Macroscopically, the tumor was consisted of yellow fatty mass and necrotic areas, which were surrounded by thin fibrous capsule. The adrenal gland was compressed at the bottom of the tumor. The weight of tumor was 290 g. Microscopically, the tumor consisted of large fat cells in direct contact with adrenal cortical cells, and it was then diagnosed adrenal lipoma. Postoperatively, the patient no longer experienced left abdominal pain and there has been no recurrence in the 31 months since the operation.

Lipomas occur through the intestinal tract, from the hypopharynx to the rectum, the colon having the highest incidence, where lipomata are the commonest benign neoplasm after adenomata. Nevertheless they are uncommon. CASE REPORT. 1) A 68-year-old man presented as an emergency with abdominal pain associated with bowel obstruction. He had a 2 to 3 month history of intermittent right-sided abdominal pain, constipation spontaneously resolved. At laparotomy there was a mass of the transverse colon, next hepatic flexure. A right hemicolectomy was performed. The patient made an uneventful recovery. Histologic examination showed a lipoma of the submucosal plane. 2) A 65-year-old man presented as an emergency with lower abdominal pain associated with a prolapsed rectal polyp. He had 1 month history of passing fresh blood per rectum. Ap ast colonoscopy revealed a large polypoid lesion in the descending colon. Transanal examination revealed a polypoid lesion with a maximum diameter of 4 cm, acting as an intussuseptum. Transanal polypectomy was performed. At laparotomy there was an intussuseptum of the descending colon into the rectum: a left hemicolectomy was performed. Histology showed the polyp to be a submucosal lipoma. DISCUSSION. Lipomas are the most common benign nonepithelial tumors of the colon. Lipomata of the large bowel are reported as incidental findings in 0.3-0.5% of cases in large series of autopsies. In the wall of the intestine most lie in the submucosal plane, less frequently they are found in the subserosal plane. The commonest site for symptomatic solitary large bowel lipoma is the ascending colon, including the caecum, followed by the transverse colon, including both hepatic and splenic flexure, descending colon, sigmoid colon and rectum. The peak incidence for lipomata of the large bowel is in fifth-sixth decade. Colonic lipomas are generally asymptomatic but occasionally patients may have intermittent crampy abdominal pain secondary to intussusception of a pedunculated lipoma or with intermittent fresh rectal bleeding. On barium enema lipomas appear circular, ovoid, well demarcated, and smooth. A barium enema showing a relatively radiolucent mass, caused by the radiolucency of fat, is suggestive of a lipoma. The water enema, with water as the contrast agent, accentuates the difference in density between a lipoma and surrounding tissues. Another characteristic feature of lipomas on barium enema is said to be their fluctuation in size and shape during the study: "squeeze sign". Lipomas of the large bowel can be seen, however, by colonoscopy. On computerized tomography scan the lipoma has a uniform appearance and density. In expert hands pedunculated and sessile lesions can be removed endoscopically, but often large bowel lipomata are treated on the basis of a presumptive malignant diagnosis with exploratory laparotomy. CONCLUSION. Colonic lipomas, although unusual, continue to present difficulties in the preoperative differentiation between malignant and benign colonic neoplasm. Two cases of colonic lipomas are reported.

During a seven year period 18 benign small intestinal tumors were histologically documented in patients referred to us for a small bowel study, using a barium infusion technique. These included seven leiomyomas, five adenomatous polyps, two Peutz-Jeghers hamartomas, one myoepithelial hamartoma, one lipoma, one Brunner's gland adenoma and one neurilemmoma. Ten of the patients were women and eight were men, with their ages ranging from 20 to 75 years (mean age 45 years). Presenting symptoms were gastrointestinal bleeding in 12, anemia in 9, abdominal pain in 4, partial intestinal obstruction in 3 and bloody diarrhea in one. The time elapsed from onset of symptoms to radiological diagnosis ranged between one month and seven years (mean time 16 months). Multiple lesions were encountered in four cases and solitary in fourteen. The site of involvement was the duodenum in 3 patients, the jejunum in 8 and the ileum in 7 of them. Main radiological appearances included solitary or multiple intraluminal filling defects, mass effect on neighbouring loops and dilation of intestinal loops proximally to the lesion. The primary tumor, in the form of a mass or other abnormality of the small intestine was identified in all study cases. Correlation with surgical or endoscopic findings showed that radiology depicted all single lesions, whereas multiple lesions were underestimated in one case. The individual morphological changes shown on examination of the resected specimens resembled the appearances on the barium study in all cases. However, enteroclysis missed four out of seven ulcers and a stalk in one of the five pedunculated lesions. A specific tumor-type diagnosis was reached preoperatively in eleven patients, it was suggestive in five and mistaken in two of them. Our experience indicates that enteroclysis is an effective means in evaluating patients with suspected benign small bowel tumors, preoperatively.

With the exception of lipoma, neoplasia of the gastrointestinal tract is rare in horses. Lymphosarcoma is the most common neoplasm of the hematopoietic system in horses. In horses with lymphosarcoma of the large colon, clinical signs may include intermittent signs of mild abdominal pain, weight loss, pyrexia, and pelvic flexure impaction caused by impingement of the colonic lumen by the mass. Peritoneal fluid analysis may be normal or have a high total protein concentration. If signs of metastasis are not evident, resection of the large colon affected by the mass may prolong survival.

During CT scanning, a pancreatic lipoma was diagnosed in a 70 year-old woman presenting with abdominal pain, elevated amylase and abnormal liver function tests. The patient underwent surgical excision of the lipoma located in the head of the pancreas. The postoperative course was uneventful. This is the third case of pancreatic lipoma described in the literature. It is a very rare neoplasm that should be included in the category of "non-ductal" tumors of the pancreas. The role of different diagnostic tools for the differential diagnosis of ductal pancreatic adenocarcinoma is discussed.

A case study of a patient who presented with abdominal pain and a palpable mesogastric mass is discussed. Ultrasound and computed tomography (CT) demonstrated that the palpable mass was jejunojejunal intussusception of the small intestine. The lead point of the intussusception was a lipoma that appeared in the CT scan as a small intramural mass with an attenuation coefficient of fat.

The observation of a case of intestinal intussusception caused by lipoma of the colon prompted the authors to review the literature on the subject and to examine the main characteristics of lipoma of the colon which represent the most frequent benign neoplasia of the large intestine after adenomatous polyps. Lipomas of the colon are localised in 90% of cases at the submucous level, are usually solitary, of varying size and may be sessile or pedunculated. They are almost always asymptomatic; only when they are of a reasonable size do they become manifest following alterations of the alveus, rectorrhagia, abdominal pain or the occupation of the colic lumen by the mass, or intestinal intussusception caused by the progression of the pedunculated lipoma. This difficult diagnosis may be aided by colonscopy with biopsy and dual contrast opaque enema. The prognosis of the disease depends on the presence or absence of complications and, in the case of the former, on early diagnosis and treatment. Lipoma of the colon of less than 2 cm may be electively removed endoscopically, those greater than 2 cm by laparotomy or laparoscopy. In emergency cases, it is advisable to perform a more or less extensive resection of the colon depending on the size of the tumour. In the case reported by the authors, an intussusception manouevre was first performed followed by left segmentary colectomy.

Colonic lipomas are often asymptomatic, but large lipomas may produce abdominal pain, diarrhea, constipation, hemorrhage, and intussusception. We report a young woman with a colonic lipoma who presented as an acute abdominal emergency with total colonic obstruction and severe pain associated with intussusception and extrusion of the tumor through the anus. The case was interesting because of its presentation after a double-contrast barium enema and because of the patient's young age and the tumor's location on the left side of the colon.

We report a 63-year-old man who presented with a history of intermittent vague abdominal pain, diarrhea, and weight loss. Colonofibroscopic examination disclosed an ileocolic intussusception with a polypoid tumor on the leading edge of the intussusception. Both double contrast barium enema and computerized tomography of the abdomen confirmed this finding. The excised specimen had an ulcerated ileal lipoma with enteritis cystica profunda on the overlying epithelium.

A patient with a history of epigastric abdominal pain and occasional vomiting is presented. During the study of an upper gastrointestinal hemorrhage, gastroduodenal invagination secondary to a gastric lipoma of 5.5 cm in diameter was diagnosed. Upper digestive endoscopy and gastroduodenal study were not diagnostic. Echography detected a duodenal mass suspect of invagination. CAT diagnosed the lipomatous nature of the tumor. Surgery confirmed gastroduodenal invagination with a gastric lipoma with ulceration in the mucosa which covered the same. Enucleation of the tumor was performed. Histologic study established the diagnosis of gastric lipoma. The post operative period was uneventful. A review of the clinical, diagnostic and therapeutic aspects of this rare disease is reported.
