Abstract Liposarcoma is the most common primary malignant tumour of the retroperitoneum. As the retroperitoneum is a large space, these tumours can grow significantly before diagnosis. In this case, a 67-year-old male was admitted to a hospital with the complaint of weight loss and abdominal distension. A palpable mass was detected on physical examination, the A scan of this showed it to be retroperitoneal, heterogenous, with multiple septations, calcifications and solid components.

Abstract Renal angiomyolipoma is a benign, rare type of tumour which consists of mature adipose tissue, thick-walled blood vessels, and smooth muscle cells. This tumour can grow to a large size, and is then defined as giant. We are describing the case of a 34-year-old female with a giant renal angiomyolipoma, measuring 32cm x 28cm x 6cm, which caused her pain and constipation. The mass was removed successfully, and partial nephrectomy was done.
