Endometriosis is a clinical entity characterized by the presence of normal endometrial mucosa abnormally implanted in locations other than the uterine cavity. Endometriosis can be either endopelvic or extrapelvicdepending on the location of endometrial tissue implantation. Despite the rarity of extrapelvic endometriosis, several cases of endometriosis of the gastrointestinal tract, the urinarytract, the upper and lower respiratory system, the diaphragm, the pleura and the pericardium, as well as abdominal scars loci have been reported in the literature. There are several theories about the pathogenesis and the pathophysiology of endometriosis. Depending on the place of endometrial tissue implantation, endometriosis can be expressed with a wide variety of symptoms. The diagnosis of this entity is neither easy nor routine. Many diagnostic methods clinical and laboratory have been used, but none of them is the golden standard. The multipotent localization of endometriosis in combination with the wide range of its clinical expression should raise the clinical suspicion in every woman with periodic symptoms of extrapelvic organs. Finally, the therapeutic approach of this clinical entity is also correlated with the bulk of endometriosis and the locum that it is found. It varies from simple observation, to surgical treatment and treatment with medication as well as a combination of those.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1968087883113362.

In our experience, the estimated incidence of SRPs is 3.95 cases/100,000 patients/yr. SRPs occur more commonly in men (ratio 3:1). Squamous papillomas occur commonly during the fifth decade of life, glandular papillomas predominate in the sixth decade, and the distribution of mixed type papillomas is from the third to the sixth decade of life. Malignant transformation was observed in a minority of patients.

The immediate postoperative, intraperitoneal administration of 5-FU inhibited wound healing. However, when the colonic anastomoses were covered with fibrin glue, the injection of 5-FU had no adverse effects on the healing of the anastomoses.

The aim of the present study was to evaluate the effect of glue tissue on the healing of colonic anastomosis in rats. Two groups of 20 Wistar rats each were used. Following laparotomy, a segment of 1 cm of the colon was resected, 10 cm from the ileocecal valve. In the control group, the anastomosis was sutured in a single layer with 6-0 polypropylene interrupted extramucosal sutures. In the glue group, the anastomosis was performed by using 2-octyl cyanoacrylate (Dermabond, Ethicon). Rats were sacrificed on day 7 following operation. Integrity of the anastomoses, existence of perianastomotic abscess or peritonitis, and adhesion formation were recorded. Anastomoses were resected including a 2.5-cm of bowel on either side. Bursting pressures were measured and the specimens were sent for histological examination. Anastomotic dehiscence occured in 20% of the animals in each group. Adhesion formation was more extensive in the glue group compared to the control group, but this difference was not statistically significant (p=0.074). Bursting pressures of the anastomoses between the two groups were not statistically significant (p=0.897). The wound healing process, as assessed by inflammatory cell infiltration, blood vessel neodevelopment, collagen deposition and fibroblast activity, did not differ statistically between the two groups (p>0.05). In conclusion, 2-octyl cyanoacrylate provides, under experimental conditions, a sutureless anastomosis equal in healing to the conventionally sutured one. The outcome may differ under demanding clinical situations.

Interleukin 7 and 15 are considered powerful pro-inflammatory cytokines, they have the ability to destabilize chromosomes and induce tumorigenesis. Additionally, they can control malignancy proliferation by influencing the tumor microenvironment and immune system. Immunotherapy has been proposed as a treatment modality for malignancy for over a decade; the exact mechanisms of action and pathways are still under investigation. Interleukin 7 and 15 have been extensively investigated in hematological malignancies since their mode of action influences the stimulation of the immune system in a more direct way than other malignancies such as lung, melanoma, and breast, renal and colorectal cancer.
