Littoral cell angioma, a rare tumour of the spleen

History and pre-admission findings: Routine abdominal sonography of a 51-ye ar-old man 6 years after removal of the right testis and radiotherapy for a seminoma revealed a 3 cm mass within the spleen. Investigations: All biochemical tests were normal. Computed tomography (CT) and magnetic resonance imaging confirmed the tumour which had not been pre sent on the CT before the seminoma had been treated, No other space-occupyi ng lesions were found in the thorax and abdomen. Treatment and course: A splenectomy was performed because a metachronous me tastasis of the seminoma was suspected. The operation and subsequent course were uneventful. At operation the tumour had been diagnosed as an haemangi oma because of its gross appearance, but histological and immunohistochemic al examination revealed a littoral cell angioma. Conclusion: The littoral cell angioma is a benign vascular lesion in the re d pulp of the spleen, which may be caused by different stimuli such as chro nic infection or tumours. This case illustrates, that this tumour should be considered in the differential diagnosis of an unclear neoplasm in the spl een.
