    This study reports the first case of Tn polyagglutination preceding acute myelogenous leukemia. Chemotherapy led to remission of both the leukemia and the Tn polyagglutination.

    Area of Science:

    • Hematology
    • Transfusion Medicine
    • Oncohematology

    Background:

    • Tn polyagglutination is a rare blood group phenomenon.
    • It is characterized by the expression of Tn antigen on red blood cells.
    • This antigen can cause transfusion complications.

    Observation:

    • A 66-year-old male presented with Tn polyagglutination during splenectomy for thrombocytopenia.
    • The polyagglutination was confirmed through various serological and biochemical tests.
    • The condition persisted for several years.

    Findings:

    • The patient later developed acute myelomonocytic leukemia.
    • Chemotherapy achieved remission for both the leukemia and the Tn polyagglutination.
    • This is the first documented instance of Tn polyagglutination preceding acute myelogenous leukemia.

    Implications:

    • Tn polyagglutination may be an early indicator of underlying hematological malignancies.
    • Further research is needed to understand the link between Tn polyagglutination and leukemia.
    • This case highlights the importance of careful blood group investigation in patients with unusual serological findings.
