[Peno-gingival syndrome. A male equivalent of vulvo-vagino-gingival syndrome?].

A 52-year-old man presented with a chronic erosive gingivitis associated with eroded genital lesions which caused preputial adhesions. Histological examination of the gingival lesions showed typical changes of erosive lichen planus. A few months later, pseudo-peladic alopecia of the vertex and lichen planus lesions of the mouth appeared. Local steroids were ineffective to treat oral erosions, but the lesions were not painful. After one year, all changes remained unchanged. We therefore propose the diagnosis of erosive lichen planus involving the mucous membranes of mouth and genitalia; this association was never reported in male patients. This syndrome represents the exact male equivalent of the vulvo-vagino-gingival syndrome described in women. "Genito-gingival syndrome" is therefore proposed for this new clinical form of erosive lichen planus.
