Cutaneous Meningioma is a very rare neural tissue disorder that I rarely encounter in both my The Woodlands dermatology and Conroe dermatology offices. Cutaneous Meningioma can result from a developmental defect in which meningocytes from the CNS occur in the skin. Clinically, the skin lesions appear as hard nodules along the spine, forehead and scalp and occasionally in the ear canal. Some patients with Cutaneous Meningiomas have an underlying connection the CNS. The “hair collar sign” denotes a small dark area of hair or an area of hair loss surrounded by a collar of dark hair. Some Cutaneous Meningiomas may develop from an underlying intracranial meningioma by extending out through the skull. Patients with these lesions are best managed by a neurosurgery/neurology team.
