[The liver splenosis in a patient following a procedure for the malignant seminoma].

Splenosis is characterized by a presence of islets of the splenic tissue in the abdominal and, rarely, also in the thoracic cavity, most frequently as a consequence of the splenic injury. The authors describe a case of splenosis in a patient followed-up after surgery and radiotherapy for the testicular seminoma and who, 42 years ago, had splenectomy for polytrauma. With respect to the location of the splenosis in the hepatic region, the differential diagnosis was difficult, bearing in mind a possibility of the malignancy relaps. Although splenosis was highly suspected, based on the results of the examinations conducted, with respect to the preexisting malignancy, the tumor was excised. The histopathologist confirmed the diagnosis of splenosis. This case is rare in the literature, considering the time gap between the diagnosis of splenosis and the trauma.
