[Paraneoplastic hypoglycemia due to malignant histiocytoma (Doege-Potter syndrome) (author's transl)]

A case report is given on a male patient who was 52 years old when he died. 9 years ago a nephrectomy was performed because of a densely-packed mesenchymal tumor of the adipose tissue of the pelvis renalis. 7 years after the surgical intervention he suffered from several hypoglycemic crises. An operation was performed, and 2 large tumor nodes were removed from the greater omentum. A retroperitoneal relapse was inoperable. Nevertheless, the disorder of the carbohydrate metabolism disappeared after the operation. At the autopsy, one year later, a large retroperitoneal tumor with metastases in the lymph nodes was found. The neoplastic growth was classified as a malignant histiocytoma, and the hyperglycemia was taken as a paraneoplastic syndrome (Doege-Potter).
