title: Pigment in the lining of nasopalatine duct cysts: report of two cases.
abstract: In a review of 20 nasopalatine duct cysts, two cases were encountered with a pigmented epithelial lining. In the literature we have found one similar case only. The pigment in our cases was shown to be melanin. The authors suggest that the melanin-containing epithelial cells are derived from Jacobson's organs and, therefore, most likely should be considered olfactory epithelium.
