Lichen planus and vitiligo are common skin disorders. Colocalization which is rarely reported may consider the koebner phenomenon related to the photo damage causing initiation of lichen planus over vitiliginous skin. We report a 37-year-old mother and her 23-year-old daughter, both farmers and known cases of vitiligo with subsequent gradual onset of pruritic skin lesions of lichen planus start...

Association of lichen planus and cutaneous malignancies is rare. Reports of neoplastic changes are mostly related to buccal chronic erosive lichen planus. We report herein a 29-year-old man who developed squamous cell carcinoma on previous lesions of chronic hypertrophic lichen planus of lower legs. Careful follow up of patients with chronic lichen planus and biopsy sampling of uncommon lesions...

A 43-year-old man with generalized lichen planus demonstrated serum antibodies against autologous lesional skin. Indirect immunofluorescence using serum and papular lesional skin revealed a lichen planus specific antigen found only in the granular layer. The specific tissue antigen was not detected in normal skin from this patient, in normal skin from patients with skin disorders other than lic...

Ulcerative lichen planus of the feet is a rare variant of lichen planus. We report a case presenting with chronic painful ulceration of the feet and cicatricial changes of the toenails. The pathology of the ulceration showed diagnostic of lichen planus. She also had typical lichen planus on the dorsal hands. The ulceration was resistant to many kinds of topical agents, but completely healed wit...

Dysphagia is not uncommon in gastroenterology practice. The differential diagnosis is wide and includes both mechanical and motility causes. Esophageal lichen planus is uncommon but now increasingly recognized. It occurs in more than half of cases of lichen planus with muco-cutaneous involvement. Often there is a delay in diagnosis and subsequent treatment. The endoscopic picture of esophageal ...

Lichen planus is an uncommon disease in children, and only 2 to 3% of affected patients are under twenty years of age. This dermatosis may appear in several clinical forms, which vary according to the morphology and distribution of lesions. In less than 0.2% of all lichen planus cases, the lesions are distributed along the lines of Blaschko, and is a variant called linear lichen planus. This is...
