Primary extra-cranial meningioma of head and neck: clinical, histopathological and immunohistochemical study of three cases.
Extracranial meningiomas of the head and neck region are rare neoplasms, the majority being a secondary location of a primary intracranial tumour. We herewith report three rare cases of extracranial meningiomas, located in the temporal muscle, parotid gland and nasal cavity, together with complete pathological, immunohistochemical and ultrastructural studies. Prognosis of this tumour is generally excellent. Surgical excision is the treatment of choice, with no need for further treatment; nevertheless, differential diagnosis must consider other more common tumours of the head and neck and be based on histopathologic examination and relative techniques, including examination of frozen sections. This procedure is particularly useful assessing surgical treatment and should be performed whenever possible to exclude the malignant nature of the lesion and avoid over-treatment. All three patients underwent surgery and are alive and disease-free.
