Over the next number of weeks, he developed a persistent, productive cough, which was unresponsive to antibiotic therapy. Radiographic examination revealed a small radiopaque tooth-shaped object in the right hilar lung region.

Histological evidence for lichen planus in clinically normal perilesional tissue.

The objective of this study was to examine the histological features of apparently normal oral mucous membrane adjacent to lesions of oral lichen planus. Twenty-six patients attending an oral medicine unit with clinical lesions typical of oral lichen planus had biopsies of lesional and perilesional sites. Biopsies were examined for histopathological features of oral lichen planus.
