We report a case of an inflammatory pseudotumour (IP) involving the floor of the skull base, which demonstrated aggressive behavior both clinically and radiologically. In this case, the diagnosis was established by clinical presentation, magnetic resonance imaging (MRI), histopathological examination (HPE) and the dramatic response towards high dose steroid therapy. The clinical features improved with oral cyclophosphamide in combination with oral steroid, which were given for a period of three months.

Myxoid liposarcoma is the major subtype of liposarcoma and commonly presents in the extremities, particularly in the thigh. We introduce an unusual case of a myxoid liposarcoma presenting as a large perineal swelling occupying the para-rectal and para-anal spaces in a 49-yearold male patient. The diagnosis, management, and prognosis of myxoid liposarcoma are discussed. A literature review is performed for myxoid liposarcoma.
