Acute scleritis in porphyria cutanea tarda.

We examined three patients who had dermatologic and biochemical manifestations of porphyria cutanea tarda and localized thinning or excavation in the sun-exposed interpalpebral sclera, adjacent to the cornea. All three patients had signs of acute scleritis. The acute scleritis responded to oral indomethacin in one patient, but systemic corticosteroids were required to control the inflammation in the other two patients. Phlebotomy, protection from sunlight, and refraining from alcohol played an important part in the treatment of the patients.
