Unusual gingival epithelial proliferation: primary pseudoepitheliomatous hyperplasia.
A primary pseudoepitheliomatous hyperplasia arising in the gingiva of a 9-year-old-boy with histologic features of carcinoma was surgically excised and has not recurred after 2 years. It is suggested that the histogenesis is atypical proliferation of an aborted gingival cyst arising from dental lamina.
