Abstract: To the best of our knowledge we describe the first case showing the association of increased B cell precursors/hematogones in a
regenerating post-toxic bone marrow with subsequent development of a B-ALL. Since all immunohistochemical/moleculargenetic anaylses
have failed to identify the initial malignant leukemic clone, we suggest a close-meshed follow-up of such cases to identify potential
mechanisms for the malignant transformation of B-cell precursors/hematogones and to prevent further fatal courses. (IJCEP1001007).

Key words: Bone marrow, toxic damage, hematogones, B-ALL
