Function Studies of the Spleen Using Radioactive-Labeled and Heat-Denatured Erythrocytes and their Clinical Value

1971

The RES as an especially active, functionally versatile, and very extended system has its most important concentration of tissue in the spleen. Till now it was possible only to investigate this organ by cytological and histological methods. Clinical function tests of the spleen were completely unknown until recently. Such investigations have now become possible by labeling the blood cells with gamma-emitting radioisotopes and the development of external counting techniques.

Hämatologische Studien an der Röntgenbestrahlten Rattenmilz

1964

310 mannliche, 130 bis 180 g schwere Albinoratten erhielten als Rontgen-Ganzkorperbestrahlung 1×600 r oder 10×3 r+1×600 r mit folgenden Ergebnissen: 1. Die Lebenserwartung war in beiden Versuchsgruppen gleich; durch die 10×3-r-Rontgenvorbestrahlung wurde weder die Strahlenempfindlichkeit noch die Erholungsgeschwindigkeit beeinflust. 2. Die histologische und zytologische Untersuchung der Milz zeigte 8 Tage nach der 600-r-Rontgen-Ganzkorperbestrahlung bei etwa 3/4 unserer Versuchsratten eine sehr rege und vielgestaltige Hamatopoese; dabei wurde die von “grosen lymphatischen Retikulumzellen” ausgehende Lymphopoese vielfach von der Hamatopoese der roten Milzpulpa ubertroffen, zunachst durch ein…

Frequency and Characterization of Benign Lesions in Pancreatic Specimens of Patients Operated for the Suspicion of Pancreatic Cancer

2012

Context A final diagnosis of benign lesions is reported in up to 21% of patients who underwent duodenocephalopancreatectomy for neoplasia, whereas no data have yet been published for resection of the body-tail. Objective To investigate the frequency and to characterize the benign lesions mimicking a neoplasia in the head and in the body-tail of the pancreas. Methods We retrospectively reviewed all the pancreatic specimens collected from 2005 to 2011 in the database of the Institute of Pathology of Mainz. Patients with a final diagnosis excluding malignancy were analyzed by histological, clinical and imaging findings. Results Three-hundreds and 73 patients were identified. A final diagnosis …

A case of splenic rupture: A rare event after laparoscopic cholecystectomy

2014

Background Laparoscopic cholecystectomy (LC) is generally safe and well-accepted. In rare cases, it is associated with complications (intra- e postoperative bleeding, visceral injury and surgical site infection). Splenic lesion has been reported only after direct trauma. We report an unusual case of splenic rupture presenting after “uncomplicated” LC. Case presentation A 77-year-old woman presented with distended abdomen, tenderness in the left upper quadrant and severe anemia 12 hours after LC. Clinical examination revealed hypovolemic shock. Abdominal computed tomography confirmed the diagnosis of splenic rupture, and the patient required an urgent splenectomy through midline incision. Th…

Sclerosing Angiomatoid Nodular Transformation: Laparoscopic Splenectomy as Therapeutic and Diagnostic Approach at the Same Time

2018

Introduction. Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a rare benign vascular lesion with unknown etiopathogenesis and with definite features of imaging, histopathology, and immunohistochemistry. It was first described by Martel et al. in 2004, and to date, only 151 cases have been reported.Case Description. We report a case of SANT of the spleen detected in a 66-year-old Caucasian, without comorbidities, presented to our department with epigastric pain. We, also, presented a review of the literature.Conclusions. SANT is a benign incidentally vascular condition in the majority of cases. The wide age and gender distribution in our review is in accordance with tha…
