Abstract:
Objective:To review the clinical and pathological features, pathogenesis, and differential diagnosis of leiomyomatosis peritonealis disseminata (LPD) during pregnancy.Methods:We report the diagnosis and treatment of LPD in a pregnant woman admitted to Jiaozhou Central Hospital of Qingdao. We retrieved relevant literature from China and abroad to review the clinical characteristics and outcomes.Results:(1) Case report: The 33-year-old pregnant woman who had had previous cesarean sections was admitted at 37 +2 weeks gestation due to premature rupture of membranes 30 minutes before arriving at the hospital with a pelvic mass which was first diagnosed seven months earlier, in the first trimester. A lower segment cesarean section was performed, and the pelvic mass was removed on admission. No relapse was reported during the postoperative follow-up for 26 months. (2) Literature review: thirteen papers involving 15 cases, including the present case, were retrieved. The age at onset was 32 years old (19-47 years old); five of them had a history of myomectomy. Twelve cases had no significant symptoms, and the diagnosis was made at delivery or postpartum; the other three had noticeable features, mainly with abdominal pain. Six had obstetrical complications, including hypertensive disorders of pregnancy, premature rupture of membrane, abnormal fetal position, and oligohydramnios. Two cases had a history of assisted reproductive technology. Eleven cases delivered after 32 gestational weeks, three before 28 weeks, one aborted at ten gestational weeks due to severe complications. Twelve had cesarean section and myomectomy and the uterus and appendages were preserved. Three cases had a cesarean hysterectomy and two of them also had bilateral salpingo-oophorectomy. The pathological manifestations of seven cases were extensive and massively distributed small fibroids, similar to malignant tumor infiltration, with the diameter of 0.5 to 1.0 cm; five cases had multiple large fibroids, accompanied by scattered small fibroids. Conclusion:LPD during pregnancy is rare, and usually benign, with no obvious clinical symptoms. LPD is more likely to be misdiagnosed as a malignant tumor before the operation, and the diagnosis is usually confirmed by postoperative histopathology. A common surgical strategy is a cesarean section combined with pelvic mass resection.
