Corneal melting and scleromalacia perforans in a patient with pyoderma gangrenosum and acute myeloid leukemia.

Postoperative endophthalmitis may present in an atypical fashion (absent or minimal anterior chamber reaction) in the presence of underlying immunosuppressive disorder. The authors describe an apparently healthy 58-year-old man who displayed endophthalmitis with minimal anterior chamber reaction following penetrating keratoplasty for granular corneal dystrophy with underlying acute myeloid leukemia. Scleromalacia perforans in association with pyoderma gangrenosum subsequently developed, leading to ciliary staphyloma and corneal melting. Pyoderma gangrenosum is an uncommon, idiopathic skin disease that may also have ocular manifestations.
