A uterine prolapse associated with a leiomyoma (fibroid) was observed in a live-stranded Atlantic spotted dolphin (Stenella frontalis). A 7 cm segment of the reproductive tract including the cervix, uterine neck and caudal uterine body had intussuscepted and prolapsed into the cranial vaginal vault. In the leading edge of the intussuscepted/prolapsed uterine wall was a 6 × 3 × 3.5 cm leiomyoma expanding the myometrium. The leiomyoma and prolapse were associated with necrotizing exposure endometritis. This is the first report of a uterine prolapse associated with a leiomyoma in a cetacean. This lesion was believed to be the underlying cause of the live stranding.
在一只搁浅的大西洋斑点海豚（宽吻海豚）体内观察到子宫脱垂合并平滑肌瘤（纤维瘤）。一段7厘米长的生殖道，包括子宫颈、子宫颈部和子宫体尾部发生套叠并脱垂至阴道穹窿前部。在套叠/脱垂子宫壁的前缘有一个6×3×3.5厘米的平滑肌瘤，使子宫肌层扩张。平滑肌瘤和脱垂与坏死性暴露性子宫内膜炎有关。这是鲸类动物中子宫脱垂合并平滑肌瘤的首例报告。据信该病变是导致搁浅的根本原因。
