7.1 POJA-L1843+1338
Title: Corpus hemorrhagicum after ovulation, ovary (human)
Description: Stain: (A) Hematoxylin-eosin; (B) Azan.
(A): Extended corpus hemorrhagicum (corpus rubrum) (1) found recently and located around lining (2) of lumen of cystic follicle (3). Remnants of central blood clot (1a) within blood-soaked pre-existent ovarian stroma and intact blood vessels.
(B): Recent rupture of another follicle with blood in the antrum (4) from the decompressed lining. Mural granulosa cells (5), a faint border (arrow) followed by internal theca cells (6) and a more fibrous external theca (7).
Background: After the oocyte is released during the ovulation the reaming granulosa and theca cells of the emptied follicle initially look red due to the left blood clots (corpus rubrum or hemorrhagicum) that will seal the “ovulation window”. The remaining follicle sheath is going to be reconstructed during the first 2-3 days, and later on turns into a corpus luteum.
