[The Schloffer tumor. Morphology and clinical aspects of 3 cases].

Three cases of the so-called Schloffer tumour are presented. It is a rare inflammatory pseudotumour of the abdominal wall with aggressive connective tissue proliferation which frequently infiltrates neighbouring abdominal organs. Usually this tumour occurs several years after abdominal surgery or trauma, thus posing substantial problems in the interpretation of the clinical and morphological findings. In one of our male patients for instance, a sarcoma of the abdominal wall was suspected pre- and intraoperatively. A female patient was falsely considered to have a carcinoma of the urinary bladder. The lesion belongs to the reactive tumour-like fibromatoses and has to be distinguished from genuine soft tissue tumours, especially the abdominal desmoid.
