Abstract

STUDY DESIGN: Case report.
OBJECTIVES
To report a case of a giant intramuscular lipoma after a blunt trauma. SUMMARY OF LITERATURE REVIEW: Lipomas are the most frequent benign tumor of the mesenchymal tissue. Although the etiopathogenesis is not complete understood yet, it is known that lipoma develope with a 1% rate after traumas in the related localizations. Traumata induce hematoma and initiates inflammatory reactions in fatty tissue and can trigger the development of lipoma.
MATERIALS AND METHODS
2 years after a blunt trauma a 56years male patient developed a back mass. A massive lipoma was confirmed clinical and radiological.
RESULTS
A total excision was performed and the result was histopathologic confirmed.
CONCLUSIONS
Patients who develop hematoma after a trauma need a close lipoma progress observation which decrease the invasive treatment of post-trauma hematoma.
