Nodular fasciitis of the upper labial fascia: Cytometric and ultrastructural studies

The rare case of nodular fasciitis in the upper labial fascia is reported. Light microscopic, electron microscopic and cytometric studies were performed. The histopathology corresponded to intermediate and reactive types in the Price and Bernstein classification. Cytometric study of evaluating DNA of fibroblasts revealed a high distinct peak in myxoid and inflammatory areas. Ultrastructurally, fibroblasts and myofibroblasts were identified in the lesion. Reported Japanese cases of orofacial nodular fasciitis are reviewed and compared with the European-American literature.
