Summary
This study presents a rare case of a cutaneous meningioma on the forehead. The tumor, likely linked to prior head trauma, showed specific immunohistochemical markers.
Area of Science:
- Dermatology
- Neurosurgery
- Oncology
Background:
- Cutaneous meningiomas are uncommon skin tumors, typically found on the scalp.
- This report details a unique case of a frontal cutaneous meningioma.
Observation:
- A 55-year-old male presented with a firm, 2x3 cm forehead lesion adherent to underlying tissue.
- The lesion was covered by intact skin.
Findings:
- Incisional biopsy showed monomorphic round cells in nests, with some pseudovascular spaces.
- Immunohistochemistry was positive for epithelial membrane antigen and vimentin, but negative for vascular markers, cytokeratins, and S100 protein.
- Cranial CT scan excluded intracranial meningioma.
Implications:
- This case highlights a rare presentation of meningioma in an unusual location.
- The findings suggest a potential association between cranioencephalic trauma and the development of cutaneous meningiomas.
- Further research may elucidate the specific mechanisms linking trauma to these cutaneous neoplasms.
