salicylates and Malocclusion

Pachyonychia congenita is a rare genetic disorder characterized mainly by hypertrophy of the nails and hyperkeratosis of the skin and mucosae. Fifty percent of all patients have oral leukokeratosis, which is often painful. The case reported here is of a 41-year-old patient who had white lesions in the form of irregular plaques; these affected multiple regions of the oral mucosa and were sensitive to touch. Histological examination revealed acanthosis, parakeratosis and ballooning of the epithelial cells, consistent with oral leukokeratosis. After therapy including topical steroids and prosthetic rehabilitation, the symptoms resolved.
