Introduction

Most lipomas tend to be asymptomatic. However large lipomas, due to their size exert pressure symptoms on nerves and vessels thereby causing functional impairment. Clinically, lipomas most often present as a slowly growing asymptomatic mass. Pain is a late and uncommon symptom, usually in deep and very large lipomas and is most likely due to compression or expansion of adjac-ent soft tissues or adjacent peripheral nerve^(1,2,3,4,5)

We present a caseof 30 years old male patient who had swelling over the right gluteal region and was giving discomfort to the patient along with hip impingement.
