M. Carey et Me. Kirk, NECROTIC PSEUDOXANTHOMATOUS NODULES OF THE OMENTUM AND PERITONEUM - APECULIAR REACTION TO ENDOMETRIOTIC CYST CONTENTS, Obstetrics and gynecology, 82(4), 1993, pp. 650-652
Background: Necrotic pseudoxanthomatous nodules of the ovary, omentum,
and peritoneum are rare, and have been described as a late manifestat
ion of endometriosis. Case: A 39-year-old woman presented with acute a
bdominal pain and an abdominopelvic mass. Emergency laparotomy reveale
d a ruptured ovarian neoplasm with several liters of old blood in the
abdominal cavity. Left adnexectomy was performed, and exploration of t
he abdominal cavity revealed no other lesions. Pathologic examination
of the neoplasm showed a large endometrioma with an associated endomet
rioid adenocarcinoma. At surgery 7 weeks later, multiple pseudoxanthom
atous peritoneal and omental nodules were found. Conclusion: This case
suggests that pseudoxanthomatous nodules of the peritoneum and omentu
m may arise from a peculiar reaction to endometriotic cyst contents an
d clinically can mimic metastatic ovarian carcinoma.
