title: Ptosis Shmosis.
abstract: A 10-year-old girl presented with painless unilateral left upper lid ptosis. A nontender hard mass was palpated in the left upper lid. Blood smear was compatible with the diagnosis of leukemia. The cause of ptosis was now thought to be a mass composed of myeloid blast cells (myeloid sarcoma).
