Immunohistochemical assessment of cannabinoid type-1 receptor (CB1R) and its correlation with clinicopathological parameters in glioma.

Background: Glioma is the most frequent primary brain tumor and one of the most aggressive forms of cancer. Recently, numerous studies have focused on cannabinoids as a new therapeutic approach due to their antineoplastic effects through activation of the cannabinoid receptors. This study aimed to investigate the immunohistochemical expression level of cannabinoid type-1 receptors (CB1R) in human glioma samples and evaluate its clinicopathologic significance.

Breast adenomyoepithelioma, a case report.

Background: Adenomyoepithelioma is a rare tumor of the breast characterized by a dual/biphasic proliferation of two cell populations: the epithelial cells and the myoepithelial cells. The first case was reported in 1970. The majority of the cases are benign, but few malignant cases were reported in literature.

A giant mesenteric fibromatosis adherent to the appendix and colonic wall, case report.

Background: Mesenteric fibromatosis, is a rare neoplasm arising usually from the bowel mesentery, with intermediate behavior and local invasion potential. They can be sporadic or related to multiple factors contributions. They usually presents as an asymptomatic growth of intraabdominal mass, and can reach a large diameter before symptoms appearance.

Splenoptosis in young female, case report.

Background: Splenoptosis is an uncommon disorder defined as the dislodgment of the spleen from its anatomical location in the left hypochondrium to another location in the intraabdominal cavity. This migration is the result of laxity or absence of the ligaments that fix the spleen to surrounding structures. Splenoptosis is either diagnosed after it causes symptoms, or incidentally using different imaging modalities.

Small bowel obstruction due to splenosis 30 years after splenectomy.

Splenosis is the autotransplantation of splenic tissue into abnormal locations due to trauma or iatrogenically. Usually, this causes no symptoms, but in rare cases the mass effect of the transplanted nodules can cause small bowel obstruction. Resection of the culprit splenic tissue is recommended, but not more extensive dissection of non-involved nodules.
