Lichen planus (LP) is a common skin disorder of unknown aetiology having various morphological variants. Ulcerative and bullous forms are extremely rare and that mimicking granulomata are still rarer. These granulomatous forms often cause diagnostic problems unless they are associated with lesions of lichen planus elsewhere over the body. Ulcerative and bullous LP of the feet with permanent loss of toe nails alongwith cicatricial alopecia of the scalp[1] and ulcerative LP of the feet with serological findings of SLE[2] have been described. The ulcerative lesions are important because they can be a site for epitheliomatous transformation.[3]

A 40-year-old female patient had a big painful ulcer 2x2 cm on the ventral aspect of her left foot for 3 years. The ulcer was having a granulomatous base with irregular margins. She also had two hypertrophic lesions on either side of the ulcer. Toe nails were normal. After about 2 years she developed lesions in the buccal mucosa and lower lip that on examination showed white streaks forming lace-like pattern alongwith few violaceous patches characteristic of LP. From the association of these lesions with those of the foot, she was diagnosed as a case of ulcerative LP of the foot mimicking chronic granulomata. The diagnosis was confirmed with biopsy. She was given dapsone 50 mg tid along with topical corticosteroids. She showed dramatic response and the lesions healed within 3 months.

Ulcerative LP of the feet usually involves the toe nails causing their destruction and gradual shedding.[1] Patients have chronic, progressive, crippling, erosive and ulcerative lesions resulting in scarring and deformities. Our patient showed chronicity and progression but the toe nails were not involved and no epitheliomatous changes were seen. Dapsons has given good results in such cases as we have seen in our patient.
