[Scrotal tumour with growth to the retroperitoneum and the kidney].

Soft tissue sarcomas are a rare form of cancer that around 1000 people are diagnosed with every year in the Nordic countries. In this case report, we describe a patient presenting with scrotal swelling, which was later diagnosed as liposarcoma. The tumour grew in the scrotum, through the inguinal canal, retroperitoneal and in close relation to the left kidney. The tumour was removed with radical surgery, and histology showed a dedifferentiated liposarcoma with clean margins. This case report shows the growth potential of liposarcomas and contributes to knowledge about a rare form of cancer.
