A case of acute myelomonocytic leukemia with subconjunctival tumor.

A subconjunctival tumor in a 29-year-old woman with acute myelomonocytic leukemia was reported. The tumor was located in the bulbar conjunctiva of her left eye, with vasodilatation and slight elevation. The pathological examination of the tumor revealed infiltration by myelomonocytic leukemia cells. The patient developed numerous skin tumors simultaneously with the conjunctival tumor and died two months thereafter despite intensive reinduction chemotherapy. The clinical course of the patient suggested that subconjunctival tumor is a clinically important sign of acute relapse in myelomonocytic leukemia.
