The incidence of leiomyomas in pregnancy is approximately 1%. Their presence has been linked to spontaneous abortion, premature labor, soft tissue dystocia, uterine inertia, fetopelvic disproportion, malposition of the fetus, retention of the placenta, and postpartum hemorrhage.
This case report documents a seldom-described event of a submucous leiomyoma masquerading as retained products of conception. The patient presented 4 weeks postpartum with complaints of urinary retention and heavy bleeding with cramping. Examination revealed a large mass resembling placental tissue filling the vaginal vault. The necrotic mass was removed with blunt and sharp dissection. The final pathology report revealed a degenerating leiomyoma.
Complicating factors associated with this fibroid included a history of spontaneous abortion and preterm labor, as well as fetal malpresentation and carneous degeneration of the leiomyoma. Gestational myomas, although rare, can have an unusual appearance that may be misinterpreted.
妊娠期间平滑肌瘤的发生率约为1%。其存在与自然流产、早产、软组织难产、子宫收缩乏力、胎盆不称、胎位异常、胎盘滞留及产后出血有关。
本病例报告记录了1例罕见的事件,即黏膜下平滑肌瘤伪装成稽留流产产物。该患者产后4周出现尿潴留、大量出血伴绞痛。检查发现一个类似胎盘组织的大肿块充满阴道穹窿。采用钝性和锐性剥离术切除坏死肿块。最终病理报告显示为变性平滑肌瘤。
与该肌瘤相关的复杂因素包括自然流产和早产史,以及胎位异常和平滑肌瘤肉质变性。妊娠期肌瘤虽然罕见,但其外观可能异常,容易造成误诊。
