(A) Ultrasonography revealed a 2.7 x 2.7 cm hetero-echogenic lobulated mass on the left breast. (B) Fusion imaging and (C) maximum intensity projection imaging of positron emission tomography revealed an ill-defined ovalshaped mass with intense fluorodeoxyglucose uptake in the left breast.

Ultrasonography revealed a 2.74 x 2.69 x 2.49 cm lobulated hetero-echogenic mass in the left breast (Fig. 1A), and positron emission tomography demonstrated a strong fluorodeoxyglucose uptake (Fig. 1B and 1C).
Histologic examination of the breast. Diffuse infiltration of primitive cells into the breast parenchyma and adjacent soft tissue was noted between arrows (A: H&E, x40; B: H&E, x200).

Gun biopsy was performed, and an infiltration of primitive cells with focal terminal deoxynucleotidyl transferase-negative and CD34-positive cells was observed on histological examination, suggesting EMR of ALL (Fig. 2).
Important clinical events after allogeneic hematopoietic stem cell transplantation were depicted according to time course. Complete chimerism were maintained until day 509 (broken arrow).
