We present two cases of rare abdominal pathologies, for which the initial diagnosis appeared simple but turned out to be exceptional pathologies. The first was compatible with simple lithiasic cholecystitis with choledocian obstacle, but was diagnosed as an idiopathic multifocal retroperitoneal fibrosis, also known as Ormond's disease. The second patient presented as an acute appendicitis. After a surgical exploration of the lower right quadrant, which did not allow a diagnosis, a median laparotomy was performed, leading to the diagnosis of ileo-caecal ischemic necrosis caused by lymphocytic phlebitis.

As human will stay for long duration in isolated sites like ISS there will be a need to perform quick and reliable diagnosis to evaluate the gravity of the pathology in presence of clinical symptoms. Many pathological situations (abnormal heart rate, pericardic collection, mitral prolaps, cholecystis, renal lithiasis, normal and ectopic pregnancies, ovarian cyst, acute appendicitis, phlebitis ... ) may occur even if all the astronauts are absolutely normal and healthy preflight. Ultrasound echography and Doppler are non invasive methods easy to use in space and very well adapted and used in routine for such diagnosis at the hospital. The objective of the present project was to design a method that guarantee a reliable echographic diagnostic in an isolated site (space station or earth site) by a Medical Doctor located at the expert site that should be the Nasa control center for ISS. It is supposed that there is only a non sonographer person in the isolated site and that the transmission system (audio, video, numeric..) is the only link between the 2 sites. Two options are proposed: (a) A 3D realtime acquisition echograph that can record quickly all the echos of a volume containing the organ suspected to have a lesion, all these echo information being sent to the ground and processed by the ground experts, (b) A robotic arm that hangs the echo probe in the isolated site tele-operated (through sattelite network) from the ground by an expert in clinical ultrasound. (As the expert moves the joystick of his ground computer the robotic arm reproduces the same movements on the probe).

Appendicitis is still the most common acute surgical abdomen all over the world and its complications may be grave. We report an adult case of acute appendicitis complicated by Portal Vein Thrombosis (PVT) and ascending portomesenteric phlebitis treated successfully with antibiotics and anticoagulation with no residual morbidity. Review of published works on the subject matter is also presented.

Enterocolic lymphocytic phlebitis (ELP) is a rare disease of unknown etiology involving most often the intramural and mesenteric small and medium-sized veins of the gastrointestinal tract. The diagnosis of the disorder is based on the histopathological examination of a surgical specimen as endoscopically obtained diagnostic material is usually too superficial. Clinical manifestation of ELP most frequently is characterized by acute symptoms, such as acute abdomen, signs suggesting acute appendicitis, gastrointestinal hemorrhage, sometimes it manifests as chronic gastrointestinal complaints. We report, to our knowledge for the first time in Poland, a case of ELP with clinical symptoms pointing to acute appendicitis, on laparoscopy manifesting as a tumorous mass in the colonic wall with an unchanged appendix.

Here we describe the clinicopathological course of a 20-year-old female patient with enterocolic lymphocytic phlebitis (ELP) of the appendix vermiformis and cecal pole with increase of IgG4-positive plasma cells. The patient presented with acute abdomen, suspicious of acute appendicitis. Diagnostic laparoscopy showed tumefaction of the cecal pole and appendix vermiformis. Histologic examination revealed mural thickening and a dense lymphoplasmocytic, partly obliterative infiltrate of the veins with sparing of the arteries, diagnostic of ELP. In addition, we found an elevated number of IgG4-positive plasma cells blended in with the lymphocytes. The IgG4-to-IgG ratio accounted for >40 %. This case meets the histopathological criteria requested for IgG4-related disease (IgG4-RD) and thus opens the possibility that ELP might be part of the IgG4-RD spectrum.

IgG4-related disease is a recent entity that has been described in a wide variety of organ systems. A 46-year-old female presented with acute appendicitis accompanied by a mass-forming lesion, raising a concern for neoplasm, and therefore, hemicolectomy was performed. The lesion revealed a dense lymphoplasmacytic infiltrate accompanied by storiform fibrosis and obliterative phlebitis. The IgG4/IgG plasma cell ratio was >50%, and the number of IgG4-positive plasma cells was >100/high-power field. In order to assess the IgG4/IgG plasma cell ratio, MUM1 was employed instead of IgG to successfully estimate the plasma cell concentration. There was also a concomitant hyperplasia of S100-positive cell, which could represent dendritic or Schwannian origin and possibly play a pathophysiologic role. The hyperplasia was significant by itself that it may mimic a mass-forming lesion. This newly described entity of the past decade deserves increased recognition due to clinical implication and surgical morbidity. This is the first case of IgG4-related disease in the appendix to our knowledge that fully satisfied all the pathological diagnostic criteria. We would like to also highlight our innovative approach of evaluating the IgG4/IgG plasma cell.
