Mesenteric cysts are rare lesions, with 1 case per 100,000 hospital admission reported. They have to be differentiated from ovarian cysts, gastrointestinal duplications and desmoid cysts. The symptoms are variable, ranging from asymptomatic cases with incidental discovery to chronic abdominal discomfort and acute abdomen. They are usually correlated to the location and the size of the lesion. Abdominal ultrasonography and computed tomography may lead to a correct diagnosis, which is regularly made at the time of abdominal exploration. Surgery is the treatment of choice, consisting with the removal of the cyst, eventually associated with bowel resection. It has to be radical in order to prevent the recurrence of the disease. A case of mesenteric cyst in a sixty-nine-years-old woman hospitalized for chronic abdominal pain is reported. In this case the cyst has been enucleated from the mesentery with open surgery without the need for bowel resection.

We report a 72-year-old man with sporadic intra-abdominal desmoid tumor manifesting as acute abdomen. CT scan revealed an air-containing tumor 7 cm in diameter; three weeks later, the tumor had shrunk to 4 cm on antibiotics. At surgery, a tumor arising from the transverse colon mesentery and infiltrating the jejunum was resected. No recurrence occurred over a 1-year follow-up.

Desmoid tumors are rare benign neoplasms with high tendency to local recurrence, and they can be divided into extra- and intra-abdominal types (mesenteric fibromatosis). Eight cases have been treated in our Department from 1997 to 2006. Six patients (3 men and 3 women) affected by extra-abdominal desmoid tumors have been treated with radical excision. In two patients desmoid was intra-abdominal: 1) a 55 years old man admitted for acute abdomen and submitted, in emergency, to a laparotomy with excision of a mesenteric abscess including a jejunal loop at about one meter from Treitz; 2) 52 years old man, submitted to an elective excision of a capsulated neoplasm of the little omentum, which had caused an oppressive abdominal pain. In both cases the hystological diagnosis has been desmoid tumor. Surgical treatment of desmoid tumors must aim at radical excision to avoid frequent recurrences (25-65%); these have stimulated the research of other kinds of treatments, since a new surgical operation itself can lead to a further recurrence. Radiotherapy has been investigated with results in 79-96% of cases, antiestrogenic therapy has been used with success in 51% of patients, and high dose tamoxifen seemed to obtain a stable disease in non operable cases. Non steroidal anti-inflammatory drugs have been experimented in association with tamoxifen and chemotherapy. Conclusive results on the efficacy of these treatments have not been obtained yet, because of the rarity of the desmoid tumors even in greater Centres.

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.

Based on a representative selection of relevant references, the aim of this study was to reflect the change of the algorithm in the surgical management of desmoid tumours (DT) in cases of accompanying familial adenomatous polyposis (FAP). Main focus is concerned with the basics of differential treatment, including additional considerations on epidemiology, diagnosis, outcome and follow-up. DT are rare benign tumours that do not metastasise but tend to invade locally. In contrast to the general population, DT in patients with FAP are more common, show a different pattern of tumour sites and cause considerable morbidity and mortality. Most DT occur in the abdominal cavity and account for the majority of serious problems. Genetic disposition and hormonal factors as well as prior surgical trauma are considered causative for the development of DT. Characteristic symptoms are abdominal pain, nausea and vomiting but DT may also present as acute abdomen. CT scan determines localisation and extension of the tumour. Treatment includes various strategies of medication, surgical resection and radiation. Data concerning diagnostic and therapeutic procedures are based on studies with small case series or case reports only. Therefore data from international multicentre studies are necessary for improving the prognosis and developing reliable and stringent guidelines.

A 51-year-old male patient with no history of medical illnesses presented to the emergency department with abdominal pain and a temperature of 39 degrees Celsius. His condition deteriorated rapidly within a few hours. Clear signs of acute abdomen, raised white blood cell count and small gas-fluid levels on abdominal X ray prompted an urgent CT scan of the abdomen. The latter revealed a space occupying lesion arising from the central mesentery containing gas-fluid levels measuring approximately 9 x 9 cm. An urgent exploratory laparotomy was performed. This revealed a mesenteric mass measuring 10 x 10 cm with an abscess. Anatomopathologic investigations showed a mesenteric desmoid tumor. Both colonoscopy and gastroscopy were within normal range ruling out Gardner's syndrome with no polyps or other lesions. The patient made full recovery with radical surgery. This is to our knowledge the fifth case of a desmoid tumor presenting with abdominal abscess not associated with familial adenomatous polyposis. We therefore believe this is an important finding to report.

We report a review of 208 cases of Meckel's diverticulum among pediatric patients from one single institution. One of the aims of this report is to highlight the different diagnostic modalities of Meckel's diverticulum since a majority of cases is undiagnosed prior to surgery. Our review shows 58 cases containing gastric and/or pancreatic heterotopic tissue, including two unique cases. The first case reported is a desmoid tumor arising at the tip of diverticulum, a case that, to our knowledge, has not been previously reported. The second case involves a female patient appearing with an acute abdomen thought to be appendicitis, instead surgery revealed a diverticulum arising from the ileum. The cause of acute abdomen was due to gonococcal infection. In conclusion, we hope that this large series of Meckel's cases will enrich our readers on the differential diagnosis and preoperative diagnostic techniques of Meckels' diverticulum.
