ABSTRACT

Lichen planus pemphigoides (LPP) is a rare, acquired and autoimmune disorder. LPP clinically, histologically and immunologically appears to be a combination of lichen planus and bullous pemphigoides. LPP is usually idiopathic but some cases have been associated with drugs, phototherapy, infections and malignancy. It has different clinical variants such as presenting with only oral lesions; with oral and cutaneous lesions and with only cutaneous lesions, respectively. We present two cases with typical histologic and immunofluorescence features of LPP.

Our 55 years old male case had typical lichen planus lesions with widespread bulla and erosions; he responded systemic steroid treatment in a short time. Bulla and erosions were not prominent in our 16 years old female case and with topical treatments to her lesions improved in a short time. LPP should be considered in the clinical differential diagnosis of vesiculoerosive oral mucosal and cutaneous diseases. (Turk J Dermatol 2010; 4: 25-8)
