An Unusual Location of Ossified Intramuscular Lipoma: A Case Report
Khodamorad Jamshidi, Iman Qomashi, Mehdi Ramezan Shirazi


Lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. Some studies show that less than 1% of lipomas were ossified. We describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. To the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and hyperostosis has not been previously reported in the literature.
