“…Primary ectopic meningiomas can arise from arachnoid cells that accompany cranial nerves as they exit the GNS; such tumors have a predilection for soft tissues of the orbit, ear, atid neck. Other primary ectopic menitigiomas, of less certain origin, develop in the soft tissues of the head and rarely at sites more remote from the GNS, Each of the 3 categories of ectopic meningioma can involve the skin (1,(12)(13)(14)(15)(16), Such cutaneous involvement is invariably acquired and has the microscopic appearances of conventional meningioma. There is an additional group of meningeal lesions, often congenital, that arise entirely within the skin (15,(17)(18)(19)(20)(21)(22)(23)(24)(25).…”

We studied 5 primary cutaneous meningiomas. All were congenital. Four were nodules or plaques on the scalp, and one was a lumbar polyp. Two were alopecic. A skull defect was present deep to one lesion, and the lumbar polyp was attached to dura. The tumors were concentrated in the subcutis, where strands of meningocytes were embedded in dense collageous tissue. Meningocytes wrapped around collagenous fibers, producing "collagen bodies". These formed the nidus for calcification that included psammoma bodies. Meningocytes also dissected between collagenous fibers, creating anastomosing spaces that mimicked a vascular tumor. Meningothelial-lined clefts, several milimeters in length, were present in 4 cases. Two lesions extended through dermal defects into the superficial dermis, where adnexa were reduced or absent. The meningocytes contained vimentin and epithelial membrane antigen. They lacked cytokeratin, S100 protein, and endothelial markers. The meningothelial lesions described herein lack the nodular and sheet-like growth patterns that typify meningiomas of the central nervous system and most primary ectopic meningiomas, including some that develop within the skin. They appear closely related to meningoceles and should be viewed as developmental abnormalities rather than neoplasms. The term "rudimentary meningocele" seems appropriate for these lesions.

“…3) Meningiomas of unusually large size have been described in the literature. 4,6,10,11,13) These tumors occurred in both intra-and extracranial locations. Massive meningiomas that presented as skull and scalp swellings commonly caused death due to ulceration and infection of the overlying scalp.…”

A 55-year-old man was admitted with a swelling on the top of his head progressively growing for 2 years. The swelling had grown to a huge size with the appearance of a double head. A huge meningioma with predominantly extracranial growth and invasion into the superior sagittal sinus was subtotally excised. The excised tumor mass weighed 1380 g. The residual tumor was treated by irradiation. No recurrence was seen at one-year follow-up examination.
