Case report of a rare bullous variant of oral lichen planus

The aim of this report is to describe the lichen planus on the oral mucosa in the bullous variant of the disease. It is often misdiagnosed with other mucosa disorders (allergies, bullous dermatosis). A 37-year-old-female patient presented for oral mucosa painful lesions of 3 months duration. A microscopic examination of the lesional areas was consistent with the diagnosis of oral lichen planus and direct immunofluorescence confirmed it. This case showed that although a rare condition the variant of bullous lichen planus can be encountered in daily clinical practice.
