A case report on aggressive giant cell tumor of greater trochanter: a divergent site

Abstract Background Giant cell tumor is a of benign nature which usually arises in the long bone, but it can also be seen at unusual sites. Only few cases have been reported so far regarding involvement greater trochanter femur as very divergent site for giant tumors; our case one them. tumors are 20–40 years age metaepiphyseal regions bones. If has to involved, distal end usually. Case presentation We present 45-year-old female with chief complains swelling and left hip pain since over month. Magnetic resonance imaging was done where location extent found. What makes this interesting that on fine needle aspiration cytology lesion showed multinucleated osteoclasts background osseous matrix spindle cells suggesting tumor. Conclusion It sometimes tricky make diagnosis these lesions typical features may not present, hence, such circumstances helping clinicians additional information like location, extent, margins utmost importance.
