Retroperitoneal liposarcoma is a rare malignant tumour with an incidence of 2.5 per million people annually. It is the most common type of all the retroperitoneal malignant tumours. Early diagnosis of the tumour is difficult because of absence of specific clinical presentation. Symptoms would only occur if the tumour exhibits pressure on the surrounding organs. It usually occurs between the fourth to sixth decades of life affecting both genders equally. Histological subtypes include: well-differentiated, poorly differentiated, myxoid, round cell and pleomorphic. Radiological imaging useful in diagnosis include: ultrasonography, computed tomography and magnetic resonance imaging. Complete surgical resection of the tumour and the adjacent viscera involved or organs remained the mainstay of treatment. Radiotherapy plays a role in reducing the risk of recurrence but its effect on the overall survival of patients is not known. The case presented is a 48-year-old male patient with retroperitoneal liposarcoma, treated by complete surgical resection of the tumour and right hemicolectomy and currently on follow-up for possible recurrence.
