Uterine adenomatoid tumors (UATs) are benign tumors of the uterine serosa and myometrium that originate from the mesothelium and forming gland-like structures. This study was conducted in order to determine the true incidence of UATs, which are usually an incidental finding during uterine surgery performed for other causes. UATs may resemble pre-existing vessels and lymphatic ducts, as well as metastatic adenocarcinomas. A total of 199 consecutive surgical operations (134 hysterectomies and 65 uterus-preserving tumor excisions) were performed by a single team of gynecologists and examined by a single attending pathologist, who performed a thorough macro- and microscopic examination of all the specimens. UATs were identified in nine (5%) out of the 199 cases [six (5%) out of the 134 hysterectomies and three (5%) out of the 65 uterus-preserving tumor excisions]. Therefore, the true incidence of UATs may be significantly higher than 1%, which is the incidence reported in the presently available literature.
子宫腺瘤样瘤（UATs）是子宫浆膜层和肌层的良性肿瘤，起源于间皮并形成腺样结构。进行本研究是为了确定UATs的真实发病率，UATs通常是在因其他原因进行子宫手术时偶然发现的。UATs可能类似于原有的血管和淋巴管，以及转移性腺癌。由一组妇科医生进行了总共199例连续手术（134例子宫切除术和65例保留子宫的肿瘤切除术），并由一名主治病理学家进行检查，该病理学家对所有标本进行了全面的大体和显微镜检查。在199例病例中有9例（5%）发现了UATs [134例子宫切除术中6例（5%），65例保留子宫的肿瘤切除术中3例（5%）]。因此，UATs的真实发病率可能显著高于1%，这是现有文献报道的发病率。
