title: Naked megakaryocyte nuclei: a clue to malignancy.
abstract: Bone marrow smears from 63 patients with various malignancies and a series of 51 controls were examined for the presence and percentage of naked megakaryocyte nuclei (NMN). Patients with malignancy had more than 15% NMN, which, when compared with the incidence in controls, was statistically significant. The etiology of this artifact is unknown. It is a clue to the presence of malignancy, and might be useful in following treated cases of malignancy for evidence of relapse. NMN should not be confused with metastatic malignant cells.
