    Myeloid sarcoma (MS) is a rare extramedullary manifestation of acute myeloid leukemia, often misdiagnosed as primary tumors.

    The case study details a 68-year-old woman with sequential MS in the nasal cavity and breast, occurring 6 years apart.

  • 3

    Initial nasal MS was diagnosed through histopathological and immunohistochemical analyses, leading to complete remission.

  • 4

    The patient's breast nodule was initially suspected as a primary malignancy but confirmed as an MS relapse via IHC.

  • 5

    This case underscores the importance of comprehensive IHC panels in differentiating MS from poorly differentiated carcinomas.
