An unusual facial location for a meningioma. Case report

Meningiomas are the most common primary tumors of the central nervous system (CNS), but their occurrence in extracranial locations such as soft tissue or skin is extremely rare. They may be congenital (Type I), ectopic soft tissue meningiomas (Type II), or secondary to an intracranial meningioma (Type III), according to the López classification. We report the case of a woman with a history of multiple intracranial atypical meningiomas (WHO grade II) who presented with a subcutaneous lesion in the left malar region. Histopathological examination confirmed the diagnosis of atypical meningioma (WHO grade II). This case represents a rare example of a Type III cutaneous meningioma according to the López classification. It underscores the importance of considering extracranial meningiomas in the differential diagnosis of facial subcutaneous masses, particularly in patients with a history of intracranial meningioma.
