正常子宮肌肉發生肌瘤是很常見的,然後,在苗勒氏管遺蹟長出肌瘤非常罕見。本文病例為一陰道發育不良,在苗勒氏管遺蹟上長出肌瘤的病例報告。術前超音波發現比腫瘤呈現乳突狀生長,及具囊狀一固體狀成份,所以術前診斷斷疑為卵巢癌症。術後病理發現此為一苗勒氏管遺蹟長出的肌瘤,因肌瘤產生透明變化及軟骨狀變生,幾乎沒有此種病報告。
Leiomyoma are very common in the normal uterus; however, they are rather rare in mullerian duct remnant. We report a case of mullerian duct remnant leiomyoma associated with vaginal agenesis. The mass had papillary growth with cystic-solid components by ultrasound. Ovarian cancer was suspected preoperatively. Finally, A fibroid with hyalinization and chondroid metaplasia was diagnosed histopathologically. To the best of our knowledge, this is the first case of mullerian duct remnant leiomyoma with degeneration, mimicking ovarian cancer by ultrasound. We provide the clinical details of this case and discuss a diagnostic pitfall.
