OBJECTIVES To assess the viability and induction of immunotolerance of nonvascularized splenic alloimplants. The phagocytic functions of splenic implants also were studied. MATERIALS AND METHODS Thirty-six adult female New Zealand and California rabbits were used, and these animals were divided into the following 5 groups: (n = 6 / groups 1-4) group 1 (sham operations); group 2 (total splenec...

Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, extremities, or head and neck regions; they are very rarely located in the abdominal cavity. The patient was a 71-year-old man who was referred to our hospital for a mass and pain in the right lower abd...

Mesothelioma is the most common malignant primary tumor of the pleura and usually associated with inhalation of asbestos fibers. In contrast, peritoneal mesothelioma is a rare entity whose pathomechanism is not yet fully understood. The coexistence of pleural mesothelioma with secondary involvement of the abdominal cavity has not been addressed in the literature. In this case report, we describ...

A 42-year-old male presented to the Emergency Department complaining of right lower quadrant pain of 2 days duration. He had no previous surgical history. On physical exam, the patient was afebrile with diffuse abdominal tenderness and peritoneal irritation. White blood cell, electrolytes, amylase and lipase serum levels were normal. A contrast-enhanced CT scan of the abdomen and pelvis (Pictur...

The patient was a 72-year-old female with the chief complaint of abdominal fullness. A giant primary myoma of the uterine cervix was suspected, and total hysterectomy was performed. Based on a postoperative histopathological examination of the tumor a diagnosis of diffuse large B-cell lymphoma (DLBCL) was made in the uterus and a mass in the greater omentum was diagnosed as a marginal zone B-ce...

Exploratory laparoscopy revealed necrosis of almost the entire greater omentum with torsion at its base and an indirect inguinal hernia with affected omentum and small bowel inside the hernia sac. The procedure was converted to a middle median laparotomy, and the omentum was ligated and resected at its base, ensuring that the entire necrotic part was removed (Fig. B). At the end, a Lichtenstein...

Primary tumors of the omentum are uncommon, and leiomyomas arising in the omentum are exceedingly rare. We report on a patient who presented with a large abdominal cyst presumed to be an omental cyst. At laparoscopy, after aspiration, the cyst was found to be attached to a solid mass arising from the greater omentum. The entire tumor was successfully excised laparoscopically. Histopathology an...
