title: Mucosal involvement in systemic and chronic cutaneous lupus erythematosus.
abstract: The prevalence and pattern of mucosal involvement in 121 patients with lupus erythematosus (LE) was investigated. Fifty-three patients had systemic LE (SLE) and 68 patients had chronic cutaneous LE (CCLE). Twenty-one per cent (11/53) of patients with SLE and 24% (16/68) of patients with CCLE had signs of mucosal involvement, but the pattern of involvement differed in the two groups. Nasal mucosal lesions were a feature in 2% (I/53) of patients with SLE and 9% (6/68) of patients with CCLE. Hyperkeratotic lichen planus-like plaques on buccal mucosa and the palate occurred in 9% (6/68) of patients with CCLE and 4% (2/53) of patients with SLE. Episcleritis occurred in 9% (5/53) of patients with SLE and not seen in CCLE. Erythematous plaques on the lower eyelids were present in 6% (4/68) of patients with CCLE and these were associated with conjunctival scarring in two patients. Vulval lesions were present in 5% (2/42) of female patients with CCLE. Oral plaques may occur when the disease is relatively quiescent elsewhere. The prevalence of mucosal involvement in lupus is underestimated as the lesions may be asymptomatic.
