Use of combined myeloperoxidase and immunogold technique in hybrid leukemia: a case report.
A case of hybrid leukemia is presented. A 30-year-old man had two blast cell populations with bone marrow. The majority of the blast cells had B-lymphoid markers on their surfaces and a small number of cells had both lymphoid markers and penoxidase activity on the same cell. Immunoelectron microscopy combined with ultrastructural cytochemistry (MPO reaction) demonstrated the biphenotypic nature of the blast cells.
