Microscopic mole diagnosis is clarified by villi size and morphology. Findings distinguish between microscopic mole and hydropic degeneration, aiding in accurate trophoblastic disease management.

Area of Science:

  • Gynecologic Pathology
  • Reproductive Endocrinology
  • Maternal-Fetal Medicine

Context:

  • Diagnostic criteria for trophoblastic disease, particularly microscopic mole, require distinct definition.
  • Morphological variations in chorionic villi between normal, aborted, and molar gestations present diagnostic challenges.

Purpose:

  • To investigate morphological changes in chorionic villi to better define microscopic mole.
  • To establish diagnostic standards for differentiating microscopic mole from hydropic degeneration and complete mole.

Summary:

  • Villous morphology, including vessel disappearance, central liquefaction, and trophoblast proliferation, were analyzed in relation to villi size (short axis).
  • Villi with a short axis ≤1,000 microns showed no specific pathological changes. However, villi with a short axis ≥1,000 microns exhibited features overlapping with complete mole, with 2 cases developing successive tumors.

  • Patients with villi ≥1,000 microns exhibiting these features are proposed as microscopic mole, while others are classified as hydropic degeneration.

    • Impact:

    • Provides clearer diagnostic criteria for microscopic mole, improving accuracy in trophoblastic disease classification.
    • Aims to reduce misdiagnosis and ensure appropriate clinical management for patients with suspected molar gestations.
    • Contributes to a better understanding of the biological behavior and progression of early-stage trophoblastic disease.
