Background/Aim: Acute lymphoblastic leukemia (ALL) is a blood malignancy characterized by a rapid proliferation of lymphoid progenitor cells. Extramedullary relapse (EMR) is the recurrence of leukemia that occurs outside the bone marrow. The central nervous system is the most prevalent site of EMR in ALL, whereas other organs, particularly the renal organs, are less commonly involved. Case Report: A 49-year-old man diagnosed with Philadelphia chromosomenegative ALL (Ph-negative ALL) received a second umbilical cord blood transplant (uCBT) and was confirmed to be in his third hematological complete remission. However, the perirenal mass lesion emerged after two weeks, and was difficult to detect on echography in the prone position. We successfully performed a percutaneous biopsy of the mass in a sitting position and pathologically identified it as EMR. After the diagnosis, chemotherapy was restarted, and the patient was scheduled to receive a third uCBT. Conclusion: This is the first report of EMR in a perirenal lesion of ALL and shows that this novel biopsy can be performed as a renal biopsy, even in a sitting position. This case is the first to describe a biopsy technique in detail and demonstrates the value of collaboration between hematologists and nephrologists in diagnosing EMR of the kidneys.
