Primary liposarcoma of the omentum: a rare intra-abdominal tumour.

Two cases of primary omental liposarcoma are described, each presenting in a different manner, thus emphasising the spectrum of clinical features associated with this condition. Treatment guidelines are laid down based upon a review of the world literature. The role of radical surgical excision in the management of this often well-encapsulated but highly malignant tumour is emphasised.
