Medication use and medical history of 155 patients with oral lichenoid lesions: a retrospective study.

ABSTRACT

Several medications have been reported as possible etiologic factors for oral lichen planus (OLP) and oral lichenoid lesions (OLLs). This study investigated the medication profile and medical history of patients with biopsy-proven OLP or OLLs, also classified by the clinically nonspecific term oral lichenoid mucositis (OLM), in a busy oral medicine clinic. The University of Florida College of Dentistry records from 2009 to 2014 were searched retrospectively for all patients with a biopsy-proven diagnosis of OLP, OLLs, or OLM. Patients were excluded if dysplasia or carcinoma was diagnosed concurrently at the same biopsy site. The demographics, clinical parameters, systemic diseases, histologic diagnosis, and direct immunofluorescence testing results were recorded. Medication category use was recorded based on both commonly used medications and those that have been reportedly linked to lichenoid disease in the literature. A total of 155 patients with an average age of 63.6 years were included. The majority of patients were women (76.8%) and Caucasian (91.8%). Most of the lesions were multifocal and mixed (white-red) in appearance. The most common systemic conditions were hypertension (n = 80; 51.6%) followed by thyroid disease (n = 52; 33.5%) and diabetes (n = 26; 16.8%). Antihypertensives were the most common medication category followed by, in descending order, nonsteroidal anti-inflammatory drugs, cholesterol-lowering medications, psychiatric medications, and thyroid replacement drugs. The records revealed that 87.7% of the patients took at least 1 medication from 1 of the categories studied. Medication use is common in patients with biopsy-proven OLP or OLLs. Although causation cannot be assessed from the results of this study, the clinician should consider the possibility of medication as a complicating factor in patients with OLP or OLLs.
