Pathogenesis

Pathophysiology

  • In jills, smooth muscle hyperplasia was found in a large number of ovaries in a published report.
  • Leiomyomas found in a significant number of ovaries, sometimes unilaterally or bilaterally.
  • They may be solitary or multiple, reaching a diameter of 1.8 cm; most are smaller.
  • Visible macroscopically as an opaque white solid mass against the pinkish-gray ovarian tissue; well defined and show ovarian tissue stretched over their surface.
  • Occasionally the myoma is embedded in the ovary.
  • The intra-ovarian myomatous tissue may be continuous with the hyperplastic smooth-muscle tissue.
  • Hydrometra (aseptic fluid within the uterus) and a persistent corpora lutea are seen.
  • Other reported ovarian neoplasms include teratoma, Leydig cell tumor and granulosa cell tumor.
