A case of an ectopic meningioma in a 67-year-old woman is presented. The tumor was located subcutaneously on the little finger of her right hand. Microscopic examination revealed a typical psammomatous meningioma with no signs of malignancy. The location of this tumor is most unusual, and theories regarding its histogenesis are briefly discussed. A neuroectodermal origin is suggested.
