Iatrogenic Seeding of Tumor Cells in Thigh Soft Tissue Upon Surgical Removal of Intracranial Meningioma.
BACKGROUND
Meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. It can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. As a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. Trauma and viruses are possible etiologies for meningioma. The ideal treatment of benign meningioma is surgical resection.


METHODS
In this case report, we present a middle-aged man with a seeding metastasis of the cranial meningioma (after its removal) in the left thigh. During the removal operation, fascia lata had been used to repair the dura mater and the skin defect was repaired primarily.


CONCLUSIONS
We believe that the occurrence of meningioma at the site of incision in the thigh is related to using the same surgical instruments for the removal of the brain tumor.
