Case report: Meningothelial hamartoma of the scalp in a 9-year-old child.

Meningothelial hamartomas represent a collection of meningothelial elements in an ectopic location. Lesions are histologically characterized as a proliferation of connective tissue elements and small- and medium-sized vessels admixed with meningothelial elements. Lesions are most often located on the scalp, present at birth, and do not extend past the subcutis. We discuss the case of a 9-year-old African American girl presenting with one such lesion on the parietal aspect of the scalp.
