Four cases of sarcoma of the small intestine (2 leiomyosarcoma, 1 fibrosarcoma, and 1 Hodgkin's disease) are described. In each case, diagnosis was the outcome of surgery: emergency operation for acute abdomen in three cases (2 mechanical ileus, 1 perforation); exploratory laparotomy for recurrent haemorrhage following negative X-ray examination per os and clyster of the digestive tract on a number of occasions. The relevant literature is surveyed. Attention is drawn to the different anatomopathological and clinical forms, and to the difficulty of diagnosis.

A case of perforated leiomyosarcoma of Meckel's diverticulum causing acute abdomen is described. In the available literature only 58 cases of leiomyosarcoma at this site have been reported, with three perforations.

The records of 101 patients with primary small intestinal malignant tumor at NTUH, collected from 1960 to 1989, were reviewed. These patients represented 1.2% of the patients with gastrointestinal cancer at NTUH over the same period. Fourty-two (41.6%) of the cancer patients had lymphomas, 30(29.7%) had adenocarcinomas, 26 (25.7%) had leiomyosarcomas, and 3(3.0%) had carcinoid tumors. The average age at cancer presentation was 47.5 years (range from 3 to 96). The lymphoma patients had an average age of 35.1 years, while adenocarcinoma patients averaged 60.4 years of age. Leiomyosarcoma and carcinoid tumors averaged 51.2 years and 59 years, respectively. There were 65 male patients and 36 female patients, and there was a male predominance in all groups except for the leiomyosarcoma group which had an equal sex ratio. Generally speaking, the incidence rate for the areas involved were similar in the duodenum, jejunum and ileum. However, adenocarcinomas were more common in the duodenum (53%) and 45% of lymphomas were found in the ileum, as were the carcinoid tumors (66%). The most common presenting symptom was abdominal pain (62%), with bleeding second (32%). Obstruction and palpable mass together were present in 29% of the cases. Body weight loss was found in 25% of patients, and 14% of the patients presented with acute abdomen due to intestinal perforation. Laparotomy was the most common diagnostic procedure (60%). Preoperative diagnoses were possible in cases of duodenal and upper intestinal malignancies, but were rarely possible in patients with lower intestinal malignancies. Sixty-eight patients (68%) underwent tumor resection for palliation or cure. The operation mortality was 4%.(ABSTRACT TRUNCATED AT 250 WORDS)

Leiomyosarcomas of the small bowel are quite rare. These tumors are mostly located in the jejunum distal of the duodeno-jejunal flexure. The non-metastasizing leiomyosarcomas have a good prognosis, according to the literature. The adequate surgical treatment is the resection of the small bowel. Chemotherapy is discussed if there is evidence of metastatic disease. For the diagnosis of leiomyosarcomas tumor markers have no significance. We report the case of a 79 years old patient with a leiomyosarcoma of the jejunum who was admitted as an emergency with an acute abdomen and underlying chronic anaemia. This case demonstrates the often unspecific symptoms and characteristics of leiomyosarcomas.

Leiomyosarcomas represent 10-20% of malignant tumors in the small bowel and 1% of those located in the large bowel. These tumors have aspecific symptoms depending on their size, location and histology. Intestinal leiomyosarcomas may be the cause of numerous types of surgical emergency. We report 2 cases of intestinal leiomyosarcoma in the jejunum and transverse colon. Both were diagnosed during an emergency exploratory celiotomy. The clinical features on admission were similar to those of acute abdomen. The main cause of surgical emergency was an extremely rare complication of gastrointestinal leiomyosarcoma: a severe hemoperitoneum. We briefly describe the surgical emergencies caused by intestinal leiomyosarcomas as well as the surgical methods employed in these cases.

Background. Uterine leiomyosarcoma is a rare and aggressive gynecologic malignancy with an overall poor prognosis. Lungs, bones, and brain are common sites of metastases of uterine leiomyosarcoma. Metastases of uterine leiomyosarcoma to the small bowel are extremely rare, and only four case reports have been published to date. Case presentation. A 55-year-old Saudi woman diagnosed with a case of uterine leiomyosarcoma treated with total abdominal hysterectomy (TAH) and bilateral salpingooophorectomy (BSO) presented in emergency room after sixteen months with acute abdomen. Subsequent work-up showed a jejunal mass for which resection and end-to-end anastomosis were performed. Biopsy confirmed the diagnosis of small bowel metastasis from uterine leiomyosarcoma. Further staging work-up showed wide spread metastasis in lungs and brain. After palliative cranial irradiation, systemic chemotherapy based on single agent doxorubicin was started. Conclusion. Metastatic leiomyosarcoma of small bowel from uterine leiomyosarcoma is a rare entity and is sign of advanced disease. It should be differentiated from primary leiomyosarcoma of small bowel as both are treated with different systemic chemotherapeutic agents.
