Lipomas are usually easy to diagnose on clinical examination. They are soft, mobile with margins that may be difficult to define. They are not usually larger than 8 cm(1). Lipomas may calcify, however, there should be suspicion of a liposarcoma especially if the patient is male, the lesion is greater than 10 cm, there is less than 75% fat, there are non-fatty areas or there are thick septae(2).
