Epithelial ovarian carcinoma (EOC) is an aggressive neoplasm, which has often disseminated to peritoneal cavity at the time of diagnosis. In order to better understand the molecular mechanisms behind EOC progression, we investigated the expression and functional role of neural cell adhesion molecule (NCAM) in this tumour type.

We report a case of a large malignant solitary fibrous kidney tumor. A complete surgical resection of the primary tumor and peritoneal disease was carried out, and a histological examination confirmed the initial diagnosis. We describe and discuss the characteristics of this rare kidney neoplasm.

The following case is reported because of the occurrence of two different types of malignant neoplasm with typical portal cirrhosis of the liver. That a pathogenetic relationship exists between Laennec's cirrhosis and primary carcinoma of the liver is generally recognized. Whether the association of a peritoneal sarcoma with the cirrhosis in this case was more than a coincidence seemed an inter...

A 61-year-old woman was diagnosed with rectal carcinoma. Colectomy and bilateral oophorectomy were performed. There was no peritoneal dissemination. Our case showed that colonic carcinoma coexisted with benign adnexal neoplasm. This fact suggests that the histogenesis of multiple benign or malignant tumors is likely to be secondary to an unexplained stimulus. Perhaps, the collection of cases wi...

Extraneural metastatic disease resulting from a primary central nervous system neoplasm is a rare clinical finding in the pediatric population. We report a case of peritoneal glioblastoma carcinomatosis following placement of a ventriculoperitoneal shunt and chemoradiotherapy in a 6-year-old female patient who initially presented with diffuse intrinsic pontine glioma. This case demonstrates the...

Pseudomyxoma peritonei is a relatively rare and poorly understood condition in which mucus accumulates within the peritoneal cavity. The presence of cells in the mucin, either inflammatory or neoplastic, distinguishes it from simple acellular mucus ascites caused by mucinous spillage. There is widespread seeding of the peritoneal and omental surfaces with a heavy cancerous glaze. This is princi...

Inflammatory myofibroblastic tumour (IMFT) is a relatively uncommon neoplasm with unpredictable malignant potential known to occur anywhere in the body. IMFT involving the omentum is a very rare entity with less than 15 cases reported so far. We report a case of omental IMFT in a 15-year-old girl who presented with multiple peritoneal masses on imaging and the diagnosis was confirmed on histopa...

BACKGROUND Primary diffuse leptomeningeal gliomatosis is a rare neoplasm confined to the meninges without evidence of primary tumor in the brain or spinal cord parenchyma. Cerebrospinal fluid diversion via ventriculoperitoneal shunt may be used as a therapeutic modality. Herein, we describe the first report of cytologic findings of a case of this neoplasm with shunt-related peritoneal metastasi...

AIMS AND BACKGROUND Malignant mixed mesodermal tumor (MMMT) is a biphasic neoplasm (carcinosarcoma) composed of both epithelial and mesenchymal elements. Extragenital MMMT, including primary peritoneal MMMT, is an extremely rare tumor with features consistent with its origin from the secondary Müllerian system. The neoplastic elements of extragenital MMMT presumably arise directly from the meso...

Malignant mesothelioma is an uncommon neoplasm arising in body cavities lined by the mesothelium. Immunohistochemical stains are useful for making a diagnosis, but the correct combination of antibodies as should be selected in a comprehensive assessment. A peritoneal origin combined with desmoplastic histology is an extremely rare disease entity. Here, we report a case of the primary peritoneal...
