Endometriosis presenting with recurrent massive hemorrhagic ascites and diagnosed by core needle biopsy: A case
Rationale:
Recurrent massive hemorrhagic ascites secondary to endometriosis is extremely rare in the medical literature.
Patient Concerns:
We report the case of a 24-year-old nulliparous woman presenting with severe abdominal distention, massive ascites, moderate anemia, menstrual pain, and an elevated CA-125 level.
Diagnosis:
We found a thickened peritoneum in the left lower abdomen by ultrasound during the follow-up period, and endometriosis was subsequently diagnosed by performing core needle biopsy (CNB).
Interventions And Outcomes:
The patient received medical treatment for endometriosis and had a good response to the treatment.
Lessons:
This is the first case in which endometriosis ectopic to peritoneum was diagnosed by CNB. Endometriosis should be considered a differential diagnosis when recurrent massive hemorrhagic ascites occur. CNB should be valued as a method for diagnosing endometriosis.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
