THROMBOCYTOPENIA IN CONNECTION WITH AN INFLAMMATORY BOWEL TUMOR

The acquired thrombocytopenia is part of a large number of diseases ca used by a variety of different factors. Besides the classical failure of bone marrow proliferation respectively the replacement of the bone marrow with malignant cells, there are immunological disorders and man y substances which may cause thrombocytopenia. The diagnosis of an ,,i diopathic thrombocytopenia'' is sometimes posed even at the end of int ensive diagnostic efforts. Possibly a benign neoplasia is also to caus e a massive decrease of thrombocytes. We observed preoperatively in on e patient with extensive stenosis of the sigma, caused by an inflammat ory tumor a thrombocytopenia with a level under 50 000/ml. A normaliza tion in thrombocyte blood counts appeared spontaneously after tumor re section.
