[Cancer risk after splenectomy].

Removal of the spleen may possibly affect functions of the immune system. Cancer risk following splenectomy was evaluated by performing a linked register study in Denmark from 1977-89. From the Hospital Discharge Register we identified 1103 patients splenectomized after traumatic rupture of the spleen and 5212 patients splenectomized for various malignant or non-malignant disorders and both groups were followed for cancer occurrence in the Danish Cancer Registry. No increased risk for cancer was observed among patients who underwent splenectomy due to trauma. In contrast, there were excesses of a number of specific cancers among patients who underwent splenectomy for non-traumatic reasons, but to a large extent this could be explained by factors related to the underlying disease and/or treatment of the disease.

Splenic lesions: sonographic patterns, follow-up, differential diagnosis.

This report concerns 172 patients with sonographically diagnosed benign and malignant splenic lesions. A variety of echopatterns was observed, but a differential diagnosis was often impossible without contributory clinical data. Thirteen patients underwent ultrasound-guided fine-needle biopsy for histological confirmation or therapy. In 14 cases splenectomy was performed for treatment or final diagnosis. Twenty-three patients had malignant space-occupying lesions of the spleen. 26 cases presented with normal splenic size, 47 showed splenomegaly of different extent. Lymphoma was the main basic illness in 60 patients. Thirteen cases presented with splenic metastases from other neoplasms. 71 malignant splenic lesions were hypoechoic when compared with normal splenic echotexture. Only two patients exhibited hyperechoic metastases. In three cases a 'halo' sign was seen. In 99 patients benign focal lesions of the spleen were diagnosed. These included splenic infarction (n = 36), dysontogenetic cysts (n = 23), splenic abscesses (n = 7), splenic calcification (n = 13), and hyperechoic lesions (n = 17) most probably representing splenic hemangioma.
