Effect of Allopurinol on Foreign Body Granuloma

A 68-year-old woman presented with erythematous indurated plaques on both her eyebrows. The skin lesions appeared 3 months after she was tattooed on both eyebrows. On histopathologic examination, a granulomatous infiltration was observed in the dermis with no evidence of any fungal, mycobacterial organisms. She was treated with intralesional injection of triamcinolon acetonide, but there was no improvement. After she started to take allopurinol for 5 months, the skin lesion improved without side effects. To the best of our knowledge, this is the first case of foreign body granuloma that was successfully treated with allopurinol in the Korean dermatologic literature.
