LICHEN PLANUS AND BULLOUS PEMPHIGOID

A patient with the clinical and histological features of lichen planus subsequently developed the clinical and histological features of bullous pemphigoid with immunofluorescent findings of linear basement membrane zone (BMZ) C₃ deposition and circulating anti-BMZ antibodies. This case with others in the literature suggests that lichen planus pemphigoides may actually represent co-existent lichen planus and bullous pemphigoid.     

GRISEOFULVIN THERAPY IN LICHEN PLANUS

Summary.— Thirty-four patients with lichen planus were treated in a double-blind trial in which either 500 mg of griseofulvin-FP or a placebo was issued to the patients on a random distribution basis. A significant difference was found between the results obtained with griseofulvin and those with the placebo. The favourable response to the treatment was accompanied by more or less typical histopathological features. No untoward effects, or recurrence in lesions were noted in the course of the trial.     

MELASMA-LIKE (PIGMENTED) ACTINIC LICHEN PLANUS

Four patients suffering from pigmented actinic lichen planus were studied. Clinically, the lesions are melasma-like, affecting mainly the face and exacerbating in summer and spring time. The histopathologic and immunofluorescence studies showed typical changes of actinic lichen planus. The possibility of pigmented actinic lichen planus should be considered in every patient with facial melanosis.
