Abstract

Osteolipomas are a rare variant of lipomas. We present a case of osteolipoma of external audiotry canal in a 30 year old lady who presented with right sided ear fullness since 2 years. A well circumscribed mass was found arising from right bony external audiotry canal. Computed tomography revealed a calcified lesion measuring 9 × 7 mm in the cartilaginous portion of right external auditory canal. Diagnosis of Osteolipomas was made histologically and patient was treated with simple excision of the mass under local anaesthesia.
