Proliferation of eccrine sweat ducts associated with heterotopic neural tissue (nasal glioma).
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.
