Hemangioma is the most common primary tumor of the liver. The widespread use of ultrasonography (USG) and computed tomography (CT) has made the diagnosis more common. Although the vast majority of hemangiomas are diagnosed incidentally and are asymptomatic, treatment is still controversial. Surgery is the treatment of choice, especially in giant, symptomatic hemangiomas and uncertainty of diagnosis. Twenty-two patients (median age: 46 years) underwent resection (n = 12) or enucleation (n = 10) for liver hemangioma from 1989 to 2002. The primary indication for surgery was abdominal pain. Ten patients who were treated by enucleation were compared with twelve patients who were treated by liver resection. Mean tumor size was 90 mm with a range of 40-270 mm. There were no statistically significant differences in tumor size, preoperative liver function tests, hemoglobin levels, and platelet counts between the two groups. Operative time was longer in the resection group, and statistically significant the difference was (p = 0.048). Blood transfusion requirement and blood loss during intraoperative period were higher in the resection group (p = 0.025, p = 0.01, respectively). There were three postoperative complications, 1 in the enucleation group (pleural effusion), 2 in the resection group (liver abscess and wound infection). There was no surgery-related mortality in either group. Although most hemangiomas can be removed by enucleation or liver resection with low morbidity and mortality, if the location and number of hemangiomas are appropriate, enucleation is the choice of the therapy. Hospital stay, blood transfusion requirement, and blood loss can be kept minimal by the selection of enucleation.

The occurrence of both primary gastric lymphoma and gastric adenocarcinoma in the same patient is a rare entity. The possible causative factors of synchronous or metachronous occurrence of both malignancies and varieties in the treatment modalities are reviewed according to published cases in English language medical literature.

The abdominal cocoon is a rare disease that is characterized by a total or partial encasement of the small bowel by a thick and fibrotic membrane. Thirty-five cases were reported since it was first described. It occurs primarily in females. Preoperative diagnosis is a matter of challenge and usually made at laparotomy. We report a patient with partial intestinal obstruction and abdominal cocoon which was diagnosed peri-operatively. We review the literature and discuss the etiology of this disease.

Malignant deciduoid mesothelioma (MDM) is a rare variant of epithelioid mesothelioma. This type of tumor might be associated with the asbestos exposure and carries a poor prognosis in general. MDM was first described by Nascimento et al. in 1994 in a peritoneal lesion of a young woman. And its diagnosis is frequently mistaken with florid mesothelial hyperplasia and peritoneal deciduosis. There are 44 MDM cases reported in the literature up today. A 59-year-old woman patient referred to our clinic was identified with an abdominal mass. Computed tomography of whole abdomen of the patient showed a mass with the widest transverse dimension of 65 × 60 mm at abdominal bifurcation in the mesenteric region. The patient was diagnosed with MDM after the cytopathological examination of the fine needle aspiration biopsy performed from the mass. Consequently, she received a total mass excision and right hemicolectomy under general anesthesia. The cytomorphological appearance of the ascitic fluid is detailed for the first time by Gillespie et al. and is described only in two manuscripts. In the present study, we aimed to report a case of a 59-year-old woman since she was diagnosed with MDM and because her cytological findings were further supported by histomorphological and immunohistochemical evaluations of the operation material obtained from the patient.

Postoperative intestinal obstruction in adults is rarely caused by intussusception. A case of antegrade jejunojejunal intussusception that occurred after Roux-en-Y esophagojejunostomy is described, followed by a discussion of the literature on this unusual entity.
