Preoperatively diagnosed mucocele of the appendix.

Mucocele of the appendix is an infrequent entity, characterized by distension of the lumen due to accumulation of mucoid substance and is rarely diagnosed preoperatively. If untreated, mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and the histology of the mucocele.

Duodenal gastrointestinal stromal tumor.

Background: Gastrointestinal stromal tumors (GISTs) are low-grade malignant tumors that may arise anywhere in the alimentary tract, and in the past, most of them were diagnosed as intestinal leiomyoma or leiomyosarcoma. GISTs of the duodenum make up only 4.5% of all GISTs.

Acute spontaneous chylous peritonitis: report of a case.

Acute abdominal pain with peritonitis due to sudden extravasation of lymph into the peritoneal cavity is a rare condition that is often mistaken for other causes of acute abdomen. The diagnosis of spontaneous chylous peritonitis is rarely suspected preoperatively, usually misdiagnosed with diverse common surgical emergencies. We report the case of an 81 year old female who presented with typical symptoms of acute abdomen, presumed as acute mesenteric ischemia.

Appendiceal mucinous cystadenocarcinoma with implantation metastasis to the incision scar and cutaneous fistula.

Introduction: Mucinous cystadenocarcinoma of the appendix with invasion of the anterior abdominal wall and cutaneous fistula development is a rare condition. To the best of the authors' knowledge, five such cases have been reported in the medical literature.

Methods And Results: The patient was a 68-year-old man who presented with a mass growing through the incisional scar and a skin fistula with mucinous discharge 1 year after appendectomy via McBurney's incision.

[Bleeding gastric inflammatory fibroid polyp (Vanek's tumor)].

Inflammatory fibroid polyp's (IFP) or Vanek tumor of the gastrointestinal tract represents a relatively unusual entity. IFP is an extremely rare cause of upper gastrointestinal bleeding. We report herein a case of a 30-year-old woman who had a gastric IFP complicated by gastrointestinal bleeding and obstructive symptoms.

Sporadic retroperitoneal aggressive fibromatosis: report of a case.

We describe herein a case of sporadic retroperitoneal aggressive fibromatosis. A 54-year-old man with a palpable abdominal mass was referred to our hospital for investigation and treatment. Abdominal ultrasonography and computed tomography revealed a solid mass with relatively well-defined borders in the left abdominal retroperitoneum.

[Intrabiliary rupture of the hydatic cyst complicated with acute pancreatitis].

Acute pancreatitis is a rare complication of hydatidosis, and only few reports were published previously. We report a case of a 17-year-old man, with recurrent liver hydatid cyst, who presented with severe upper abdominal pain, vomiting, jaundice. Amylase and bilirubin were elevated.

[Emphysematous necrotizing pancreatitis].

The authors present an additional case of emphysematous necrotizing pancreatitis caused by Escherichia coli. Emphysematous necrotizing pancreatitis represents a rare and potentially life-threatening infection and is characterized by gas formation within or around the pancreas. A 26-year-old man presented with severe upper abdominal pain and vomiting, 7 hours from onset.

[Organized pancreatic necrosis resembling retroperitoneal tumor].

This paper presents the case of a 29 years old patient who has an organized pancreatic necrosis, presenting preoperative differential diagnosis problems and surgical technique difficulties, revealing the fact that, in this particular case, paraclinical investigations have an orientative value, and are not offering information regarding etiology, and do not allow to establish a preoperative strategy. Tumor resection was performed; final diagnosis was established by histological examination. The follow-up period was uneventful.
