    This study details the ultrastructural characteristics of pleomorphic liposarcoma, a rare soft tissue tumor. Distinctive cellular features observed via electron microscopy aid in differentiating it from other similar tumors.

    Area of Science:

    • Oncology
    • Pathology
    • Electron Microscopy

    Background:

    • Pleomorphic liposarcoma is a rare soft tissue sarcoma.
    • This study presents an ultrastructural analysis of a pleomorphic liposarcoma case with an unusual clinical presentation.

    Observation:

    • The patient, a 69-year-old female, presented with recurrent superficial phlebitis of the left leg.
    • A mass was excised, and microscopic examination confirmed pleomorphic liposarcoma.
    • Oil red O staining revealed numerous cytoplasmic and intranuclear lipid droplets.

    Findings:

    • Ultrastructural examination showed pleomorphic cells with lipid spaces lacking a limiting membrane.
    • Cells exhibited large, pleomorphic nuclei and abundant cytoplasmic organelles, including prominent centrioles.

  • Immature and scant intercellular collagen was noted.

    • Implications:

    • The distinctive ultrastructural features aid in differentiating pleomorphic liposarcoma from other soft tissue tumors.
    • This detailed ultrastructural analysis contributes to the understanding of liposarcoma subtypes.
    • Electron microscopy is a valuable tool for precise tumor diagnosis.
