Abstract
OBJECTIVE: Several acute, usually pediatric variants of edematous, symptomatic fungiform lingual papillitis have been reported since the 1990s, most notably transient lingual papillitis (TLP); but no chronic forms have been mentioned. Is there a chronic counterpart, akin to the older palatal examples of inflammatory papillary hyperplasia? The objective of this study was to clinicopathologically characterize a previously unreported entity with clustered, chronic fibrous papules (nonsyndromic) of the tongue. METHODS: Cases were collected from clinics in 2 dental schools. RESULTS: Five women and 4 men were identified with multiple, moderately firm, slightly pedunculated, normally colored masses clustered at the tip of the tongue (n = 4), covering the dorsal surface (n = 4) or on the lateral border (n = 1); 2 showed several erythematous or edematous papules (similar to TLP) admixed with fibrous papules. Patient ages ranged from 31 to 62 years (average 49) and all lesions had been present for many years. All lesions were asymptomatic except for the lateral border lesion, which presented with a burning sensation and mild tenderness (disappeared with antifungal medication). Five cases were associated with mouth breathing or a tongue-thrust habit; 4 were associated with geographic tongue or fissured tongue. Four papules were biopsied. All were composed of dense, avascular fibrous tissue with no or very few inflammatory cells; one showed focal mild neovascularity and edema. The lesion appeared to represent altered filiform papillae, more so than fungiform papillae. CONCLUSIONS: Chronic lingual papulosis (CLP) is an innocuous entity represented by focal or diffuse enlargement of numerous lingual papillae, primarily the filiform papillae. It appears to usually have an adult onset and most likely represents papillary reaction to very low-grade, chronic irritation or desiccation. Some cases with childhood onset, however, seem to be variations of normal anatomy. No treatment or biopsy is required, but a number of systemic disorders and syndromes must be ruled out before applying the CLP diagnosis.
