Four cases of spontaneous acute hemoperitoneum due to rupture of a liver tumor are presented. The resulting acute abdomen was the first manifestation of the neoplasia. The four tumors corresponded histopathologically to a cavernous hemangioma, a bening adenoma related to anabolizing androgens, and two hepatocarcinomas in cirrhotic livers. All of the patients presented abdominal pain and shock, the characteristics of which are described in this report. One of the patients died due to cardiac arrest before surgical treatment. Emergency surgery was performed on the other three, consisting of left hepatic lobectomy and ligature of the hepatic artery for the hemengioma, and segmented hepatectomy for the adenoma and the hepatocarcinoma. Only the patient with benign tumor survived. Lastly, the authors review the literature, commenting on the clinical, physiopathologic, therapeutic, and prognostic aspects.

Angiomyolipoma is an uncommon benign tumor of the kidney. The tumor is composed of fat, smooth muscle, and blood vessels. The same pathological entity can appear in two clinically different forms, with or without tuberous sclerosis. We present two cases of renal angiomyolipomas with unusual manifestations. One was associated with tuberous sclerosis and both had the presentation of acute abdomen. Case one presented with epilepsy, angiofibroma, subungual fibroma, periventricular calcification, and bilateral renal angiomyolipomas. Tuberous sclerosis is characterized by these findings. Both cases had spontaneous hemorrhage with hypovolemic shock. Massive hemorrhage resulting in shock is uncommon and the incidence has been estimated to be about 10 per cent. In fact, many angiomyolipomas are clinically occult. The size of the tumor correlates well with the presence or absence of symptoms which include microhematuria, flank pain, hypertension and urinary tract infection. Abdominal CT is the preferred modality for diagnosis of angiomyolipoma. The most important finding is the presence of an intrarenal tumor with fat component which is recognized as a relative low density on CT. Our patients were hospitalized under the impression of angiomyolipoma after the CT study. In addition, the CT defined either the size of the tumor or the extension of the hemorrhage. Although many believe that renal angiography is not sufficient by itself to establish the diagnosis of angiomyolipoma, occasionally it is mandatory in the management of the tumor. The management is decided by two factors, the size of tumor and the clinical presentation. The attitude of management should include conservative treatment with regular follow-up, selective arterial embolization, enucleation, and partial or total nephrectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

We made a retrospective analysis of 43 cases of primary tumor of the small intestine, 28 benign and 15 malignant, diagnosed and treated in our hospital over a period of 18 years. A preoperative diagnosis was reached in 13 cases (30%), while in 37.2% the tumor was a casual finding during operation by other methods. The remaining 32.5% debuted as acute abdomen and were an emergency surgical indication. Simple tumoral resection was practiced in 19 cases (44.1%) of benign tumor, intestinal resection with end-to-end anastomosis in 22 cases (51%) and only biopsy in two cases (4.6%). Coadjuvant chemotherapy was given to five patients (11.5%) and radiotherapy to one (2.3%). The one-year survival for malignant tumors was 73%, and only 18% (2 cases) survived more than 5 years after the operation).

Lymphangioma is an uncommon tumor. Lymphangiomatosis, a benign tumor consisting of a cluster of dilated lymphatic channels, is very unusual. Most lymphangiomatoses are found in the neck and head area. Less than 5% are diagnosed intraabdominally and they are very infrequently encountered in the retroperitoneal area. Herein, we report a rare case of a 32 year-old woman who had disseminated intra-abdominal and retroperitoneal cystic lymphangiomatosis, which presented as acute abdomen. She received exploratory laparotomy due to the suspicion of malignancy, which was finally confirmed as cystic lymphangiomatosis. The clinical manifestations, imaging features, and management of this patient are discussed and compared with previous literature.

Cystic lymphangioma is a rare benign tumor that occurs more often in children with different localizations. Abdominal localization and its development may produce symptoms and clinical features of acute abdomen leading to problems in the differential diagnosis. The Authors report a rare case of pancreatic lymphangioma in a nine years old child resolved by surgical treatment. A review of the literature concerning problems of diagnosis and treatment is also presented.

The hibernoma is a rare benign tumor derived of embrionary fat seen in adult, which is usually localized in scapular and interscapular region. It express as a slowing growth bulk without symptoms. The authors present a 2 years old boy with acute abdomen requiring urgent laparotomy, that shows a tumor connected to mesocolon by a vascular pedicle that had undergone torsion. No other similar case published been found. The treatment is surgical resection although recurrences have been reported due to incomplete resection.

Renal Angiomyolipoma (AML) is a rare benign tumor As it is usually asymptomatic and small, AML sometimes may cause acute abdomen by spontaneous rupture and hemorrhage that may be life threatening in some cases for which surgical management is necessary. A 58-year-old female patient was admitted for right side and right upper abdominal pain, nausea and vomiting. Right upper abdominal and right side sensitivity were remarkable on physical examination. Whole blood count revealed the ongoing with steady remarkable decrement in hematocrite and hemoglobin. Radiological examination showed right kidney mass with retroperitoneal hematoma. Patient underwent a right nephrectomy with mass excision. Her postoperative period was uneventful. On this case report we conclude that; angiomyolipoma may cause serious complications by the spontaneous rupture and life threatening hemorrhage. In case of massive hemorrhage and/or whole renal involvement, nephrectomy is the most feasible surgical treatment of all the other treatment methods.

The ovarian fibroma is a rare benign tumor originating from the connective tissue of the ovarian cortex. On occasion, the general surgeon may encounter ovarian fibroma while operating an acute abdomen. We present a series of 15 ovarian fibromas encountered in 13 patients over 11 years experience in our general surgical ward. Only four cases required emergency operations due to either tumors or adnexal torsion. High-resolution ultrasound scan with color Doppler suggested an ovarian fibroma in only ten cases, while CT and MRI were suggestive for the diagnosis in three other cases. Surgical treatment consisted of five ovarectomies, three adnexal resections and five total hysterectomies with bilateral salpingo-oophorectomy. Seven patients underwent laparoscopic surgery, four of them for an ovarian resection and in three for an adnexectomy. Laparoscopic approach has significant advantages by limiting parietal aggression with better cosmetic results, short hospital admission, lower costs, few postoperative adhesions and rapid recovery.

Inflammatory myofibroblastic tumor (IMT) is a very rare benign tumor composed of myofibroblastic spindle cells of uncertain etiology, which can occur at any age and affect any organ system. More and more cases of IMT in children have been described in pediatric literature in recent years. However, this tumor occurring intraabdominally in children has rarely been reported in Taiwan. Here we present a 1-year-9-month-old boy who had fever and abdominal pain only for 2 days, symptoms mimicking acute abdomen. After imaging study, a huge tumor nearly 10 cm in diameter was incidentally found over the right abdomen with unknown origin and nature. After surgical removal of the tumor, IMT was confirmed by the pathological findings. It is very difficult to make an accurate preoperative diagnosis on this tumor according to past experience, so the role of pathological diagnosis with immunohistochemical study becomes important. This case illustrates that IMT should be considered as a possible cause of intra-abdominal mass in children who have fever of unknown origin.

Desmoid tumor is a rare benign tumor derived from fibrous sheath or musculoaponeurotic structure. The tumor is benign histologically but considered as malignant clinically because it has high propensity on infiltrative growth with local invasion and tendency to recurrence after local excision. Especially, when this tumor happens to be in the intra-abdomen, the prognosis is worse because it can cause intestinal obstruction, ureter obstruction and, fistula formation. It also can invade major vessels in abdomen. This tumor occurs more frequently in patients with familial adenomatous polyposis (FAP), in post-partume women, and at old surgical incision site. However, in this case, the patient had neither previous surgery nor a FAP history. We report a rare case of the young male patient who presented with an acute abdomen and underwent laparotomy and was found to have an intra-abdominal desmoid tumor with abscess formation.
