title: Proliferation of eccrine sweat ducts associated with heterotopic neural tissue (nasal glioma).
abstract: The term "nasal glioma" refers to the presence of heterotopic neural tissue, mainly glial in nature, at or near the root of the nose. We describe a case in which all three components of neural tissue, that is, leptomeninges, glia, and neurons, were present, associated with sweat-duct hyperplasia. Proliferation of sweat ducts is a reactive process in some benign and malignant neoplasms, hamartomas, and cysts. This is the first documented case of hyperplasia of eccrine ductal epithelium induced by nasal glioma.
