pubmed-article:3408260 | pubmed:abstractText | We report the clinical features of 62 consecutive patients with lichen planus observed in 18 months. The largest number of cases occurred between 50 and 70 years of age. Thirty-four patients had lichen planus only. In the remainder, lichen planus was associated with chronic liver diseases (16 cases), immune-related disorders (7 cases), and diabetes (5 cases). Mucous-erosive lichen planus was significantly more frequent in cases with lichen planus and other diseases. In all patients with liver diseases the histological features always showed a severe liver involvement. No relationship was observed between lichen planus and the etiology of the liver diseases. Females were more affected by immune-related disorders than males. The above data, together with the increased levels found of IgA, auto-antibodies, and cryoglobulins, even in cases with lichen planus only, suggest that lichen planus results from an immune imbalance, often associated with systemic involvement. | lld:pubmed |
