ABSTRACT
The pigmented purpuric lichenoid dermatitis of Gougerot-Blum is a subtype of the pigmented purpuric dermatoses characterized by small red-brown lichenoid papules that coalesce to form plaque lesions. This disorder usually persists for months to years and is resistant to conventional therapy. Pentoxifylline has been used to treat various dermatologic diseases, but its effectiveness in pigmented purpuric lichenoid dermatitis has not been reported. We tried oral pentoxifylline treatment, 400mg twice a day on a 63-year-old man with pigmented purpuric lichenoid dermatitis. A response was observed within 2 weeks. And after 8weeks, the skin lesion showed much improvement and therapy was discontinned. Four month later, he had a recurrence on the leg. He was treated again with pentoxifylline and after 3 weeks, the recurrent lesion showed resolution.

Pigmented purpuric lichenoid dermatitis of Gougerot-Blum is one of the diseases classified under the group name of pigmented purpuric dermatoses that are likely variants of each other resulting from lymphocyte-mediated leakage of erythrocytes. This is characterized by minute, rust-colored, lichenoid papules that tend to fuse into plaques with indistinct borders and develop mainly on the legs, thighs, and lower trunk. We report a case of pigmented purpuric lichenoid dermatitis of Gougerot-Blum on the lower abdomen, buttocks, and lower legs in a 69-year-old male patient.
