The authors present an unusual case of benign, solid, complex teratoma of the ovary with rupture into the rectum. A young woman, investigated for bowel problems, was found to have a prolapsing tumour in the upper rectum. A diagnosis of benign solid teratoma of the ovary was made by histologic examination of the surgical specimen; the tumour had perforated the rectal wall and protruded into the bowel lumen, a most unusual complication for this type of tumour. Pararectal teratomas can arise from either the ovaries or the soft tissues of the sacrococcygeal region. The latter do, on rare occasions, perforate the rectum. The possible mechanisms of rectal perforation by these teratomas are briefly discussed.
作者报告了一例罕见的卵巢良性实性复杂畸胎瘤破裂进入直肠的病例。一名因肠道问题接受检查的年轻女性，被发现直肠上段有一个脱垂的肿瘤。通过对手术标本的组织学检查，诊断为卵巢良性实性畸胎瘤；该肿瘤已穿透直肠壁并突入肠腔，这是这类肿瘤极为罕见的并发症。直肠旁畸胎瘤可起源于卵巢或骶尾区域的软组织。后者在极少数情况下会穿透直肠。本文简要讨论了这些畸胎瘤导致直肠穿孔的可能机制。
