Combination Therapy of Thalidomide and Low-dose Corticosteroid in the Treatment of Pemphigoid Nodularis

We report a 64 -year old male patient with recurrent generalized erythema, papule and nodularis -like eruption with severe pruritus for 2 years. Generalized, symmetrical distribu- tion of dark red papules, plaques and hard nodules were found on head, neck, trunk and limbs. Erosion or pitting scars with various size between green bean and corn were seen on the surface of most of nodules. No obvious blister was observed. Direct immunofluorescence （DIF） showed the deposition of C3 in a linear pattern at the basement membrane zone. Indirect immunofluorescence （IIF） disclosed circulating anti -basement membrane zone C3 with titre of 1：80. Histopathology showed blisters in subepidermal. The diagnosis was pemphigoid nodularis on the basis on the investigation of clinical features. Combination therapy of thalidomide and low - dose corticosteroid was administrated with satisfactory responses.
