    Pyoderma gangrenosum (PG) is increasingly linked to myeloproliferative disorders like leukemia. Two new cases of PG with acute myeloblastic leukemia highlight atypical presentations, including bullae, which can delay diagnosis.

    Area of Science:

    • Hematology
    • Dermatology
    • Oncology

    Background:

    • Pyoderma gangrenosum (PG) is a rare, inflammatory ulcerative skin disease.
    • Increasing reports link PG to myeloproliferative disorders (MPDs).
    • MPDs include monoclonal gammopathies, myeloma, myeloid metaplasia, and polycythemia.

    Observation:

    • Seven cases of PG associated with various leukemias were recently described.
    • These included acute myeloblastic leukemia, chronic myelogenous leukemia, and acute lymphoblastic leukemia.
    • Two additional cases of PG with acute myeloblastic leukemia are presented here.

    Findings:

    • Patients with PG and acute myeloblastic leukemia often present atypically.
    • Clinical features can include bullae and superficial skin involvement.

  • These atypical signs may obscure the diagnosis of PG.

    • Implications:

    • Recognizing the association between PG and acute myeloblastic leukemia is crucial for timely diagnosis.
    • Awareness of atypical presentations, such as bullae, can improve diagnostic accuracy.
    • Further research into the pathogenesis linking PG and hematologic malignancies is warranted.
