Bullous Lichen Planus - A Case Report

Abstract

Bullous lichen planus is a rare variant of lichen planus which is usually associated with pre-existing lesion of lichen planus. In general population it has prevalence of approximately ~1%. It is characterized by inflammatory and immune mediated mucocutaneous lesion and presents as vesicles or bullae clinically. Bullous lichen planus is characterized by blistering of typical lichen planus lesions. The extremities are predominantly affected. On examination tense multi-locular bullae are seen. Histopathological examination shows subepidermal bullae along with changes of lichen planus. Such patients respond to corticosteroid treatment.

Here we discuss a case of 67 year old female with complaints of fluid filled lesion all over the body since 3 months. Biopsy from the erosive area revealed hyperplastic, hyperkeratotic squamous epithelium with mild dyskeratosis and subepidermal bullae along with lymphocytic infiltration in the papillary dermis thus favoring the diagnosis of bullous lichen planus.
