A case report of a renal liposarcoma with penile metastases

Abstract

A 73-year-old man presented to his general practitioner with a left sided abdominal mass, intermittent night sweats and left sided sciatic pain on movement. A computed tomography (CT) scan revealed a well encapsulated mass arising from the left kidney, measuring 180 mm × 150 mm. Following an open nephrectomy, the tumour was confirmed as being Trojani Grade II dedifferentiated liposarcoma. Repeat CTs at four months and one-year post-surgery were clear of metastases, but after 17 months the patient presented in the emergency department with severe right-sided flank pain. A CT scan showed evidence of metastatic recurrence in the lungs, sternum and right quadratus lumborum muscle. The patient was treated with palliative radiotherapy and a repeat CT taken to assess the rate of disease progression showed a new metastatic deposit within the right penile corpus cavernosum.
