Primary cutaneous meningioma. Report of a case
Acta Pathologica Japonica
|March 1, 1987
Abstract:
A cutaneous meningioma in the left upper eyelid was found in a 51-year-old woman. Histologically, arachnoid villi-like feature, meningothelial structure, and numerous psammoma bodies were evident. In the present case, it was predicted that the tumor originated from the extracranial arachnoid cell rests.
Insights
A rare cutaneous meningioma was identified in a woman's eyelid. This eyelid tumor exhibited features suggesting origin from extracranial arachnoid cells.
Area of Science:
- Ophthalmology
- Neurosurgery
- Dermatology
Background:
- Cutaneous meningiomas are rare tumors that can occur in the head and neck region.
- Eyelid involvement is exceptionally uncommon, presenting diagnostic challenges.
Observation:
- A 51-year-old female presented with a mass in her left upper eyelid.
- Clinical examination revealed a distinct lesion requiring histological evaluation.
Findings:
- Histopathological analysis confirmed a meningioma with characteristic meningothelial structures.
- The presence of arachnoid villi-like features and numerous psammoma bodies was noted.
- The tumor morphology suggested an origin from extracranial arachnoid cell rests.
Implications:
- This case highlights the importance of considering meningiomas in the differential diagnosis of eyelid tumors.
- Understanding the origin of extracranial meningiomas aids in surgical planning and prognosis.
- Further research into the pathogenesis of cutaneous meningiomas is warranted.
