Biscotti
CV, Hart WR. Peritoneal
serous micropapillomatosis of low malignant potential (serous borderline tumors
of the peritoneum). A clinicopathologic study of 17 cases.Am J Surg
Pathol. 1992;16:467-75. Department
of Pathology, Cleveland Clinic Foundation, OH 44195-5138. Primary
peritoneal serous micropapillomatosis of low malignant potential, or serous
borderline tumor of the peritoneum, is a relatively rare lesion that is histologically
indistinguishable from peritoneal "implants" associated with ovarian
papillary serous tumors of low malignant potential. We analyzed 17 cases to further define the pathologic
features and prognosis of this entity. The ages of the patients ranged from
16 to 67 years (mean, 33 years). Eight patients
were symptomatic with
chronic pelvic or abdominal pain (five patients), adnexal mass (one patient),
small-bowel obstruction (one patient), and possible endometriosis (one
patient). In nine cases
(53%), peritoneal serous micropapillomatosis of low malignant potential was an incidental finding
discovered during evaluation or treatment of other conditions. Grossly,
the peritoneal lesions were focal or diffuse. They commonly appeared as miliary granules and often were believed to
be peritoneal carcinomatosis. Microscopically,
peritoneal serous micropapillomatosis of low malignant potential had all of the
patterns seen in superficial("noninvasive") peritoneal implants of
ovarian serous borderline tumors. Psammoma bodies
were a prominent feature of all cases. Twelve patients
also had typical endosalpingiosis. Most
patients were treated by hysterectomy and bilateralsalpingo- oophorectomy. Surgical treatment in seven patients consisted only of biopsy. Ten patients had residual
unresected disease at the time of their initial operation. Several
patients received adjuvant chemotherapy. Follow-up was available for 14 of the
17 patients. One patient
died of metastatic breast carcinoma at 3.8 years; another
patient died 7 weeks after operation, possibly as a complication of therapy.
The other 12 patients were alive at last known contact after follow-up
intervals of 8 months to 16.2 years (mean, 7.5 years). Two of these 12 patients
developed multiple episodes of small-bowel obstruction due to persistent
peritoneal serous micropapillomatosis of low malignant potential;neither
received adjuvant chemo- or radiotherapy. Both were
alive without progressive disease 10.9 and 16.2 years after initial diagnosis,
respectively. This excellent prognosis supports a
regimen of conservative therapy for these patients. 主要数据: 年龄:16-67岁,平均33岁 临床表现:有症状8例,其中5例为慢性盆腔/腹腔疼痛。因其他疾病偶尔发现9例。手术所见:局灶性或弥漫性腹膜表面粟粒状颗粒性病变,似癌症广泛转移(Carcinomatosis) 组织学观察:形态结构与非浸润性卵巢交界性浆液性肿瘤相同;砂砾体100%(17/17);输卵管内膜异位70.5%(12/17)。 治疗:全子宫+双侧附件切除8例;仅取活检9例;部分病例接受化疗或放疗。 随访:14/17例,时间8个月-16.2年,平均7.5 年。 结果:一例手术后7周死于并发症;一例3.8 年后死于乳腺癌转移;12例生存,最长者已生存16.2年。 结论:腹膜交界性浆液性肿瘤预后非常好,可保守治疗。 本例与其不同点:无砂砾体;手术后自行消退。 |

我想请大家讨论几个问题,从前后2次活检形态学上的共同点(图1-第一次和图10-16第二次)开始。
前后二次的共性为 卵巢(腹膜)表面乳头状腺纤维瘤。 复习PubMed有关卵巢腺纤维瘤文献, 其中最大一组为法国医生在1993 年的研究报道。RNS, et al. Randrianjafisamindrakotroka NS, Gasser B, Philippe E. CHU Majunga, Madagascar. 主要数据为: 1)回顾性分析10年期间855例卵巢上皮性肿瘤,腺纤维瘤为118例(13.8%) 良性100例(84.7%),恶性18例(15.3%)。 2)表面乳头状腺纤维瘤5例(4.2%),平均年龄27 岁。囊性腺纤维瘤 77.5%, 平均年龄53岁;腺纤维瘤17.5%, 平均年龄64 岁。 3)单侧性100例;双侧性118例。 4)组织学分类:浆液性110例、粘液性6例、嗜酸-透明细胞型2例。 5)形态学良性100例;恶性118例。其中13例为上皮增生、5例有浸润(平均年龄70岁)。 6)随访结果:5例腺纤维瘤伴有浸润性癌的病例中3例死于肿瘤转移、1例手术后生存了9年;1例失访。 7)5例表面乳头状腺纤维瘤临床均为良性。 请教:表面乳头状腺纤维瘤的临床病理特点?此病例的治疗建议? 谢谢! |
表面乳头状腺纤维瘤的临床病理特点(surface papillary adenofibroma):应该是乳头结构(一般比较粗大的,中心是纤维化的)+ 单层上皮。
既然是上皮就可以恶变,公认的顺序:腺瘤 --》 交界性 --》 低度恶性浆液性癌,但是肿瘤does not read textbook,所以不会总是按照套路出牌的,可以跳过交界性肿瘤直接到低度恶性的癌症或者一上来就是低度恶性的浆液性癌。还有目前认为低分化或者高度恶性的浆液性癌是直接起源于包含体腺体(surface inclusion glands或者表片上皮),分子机制跟低度恶性的浆液性肿瘤是不一样的.
"The 13 adenofibromas with atypical epithelial hyperplasia (at a mean age of 60 years) were all made of serous cells; 6 of them were low-grade and 7 high-grade tumours with 3 microinvasions"--我觉得他们的提法不确切,既然已经是癌了,就不是adenofibromas了, 只是具有结构上象adenofibromas。
本例病例应该随访就可以了,即使是交界性的肿瘤也不用化疗。
以下是引用xljin8在2010-1-13 20:30:00的发言: 谢谢曹医生和Dr.wfbjwt的宝贵意见,要注意活检部位的差异、怀孕期长期高激素水平对微浸润的影响、和可能引起的A-S反应。 |
这是个很有意思的病例。 焦点在于:第一次活检所见的“交界性肿瘤”是否是由于A-S反应引起的,而肿瘤本来是cystadenofriboma/cystadenoma, 然后在孕激素退了以后,肿瘤回复到原来的面目?
对于第一个问题:我认为一般认为腹膜是种植的。
第2个问题: 可能性是存在的。组织学上也象。
第3个问题: 经典型卵巢浆液性乳头状瘤合并妊娠目前文献上有些报道,但是A-S 反应样的改变还没有报到。
我现在最想知道的是: 第一次和第2次手术腹膜和大网膜的组织学对比? 是否第一次手术在腹膜显示的是“交界性的”而第2次是腺瘤样的改变? 如果是这样,那么就比较支持A-S样的反应。
我希望能看到片子就好了。金老师请查您的短信。
以下是引用天天田田在2010-1-14 5:41:00的发言: 我在一月前遇到一例剖宫产(23岁),卵巢囊实性肿块21*15*15cm,最后诊断:黏液性交界性肿瘤,伴局灶上皮内癌;当时曾怀疑与妊娠有关,建议患者去上海红房子会诊,结论与我们一致;患者也未作进一步治疗,目前还在随访中。 今天看到金老师的病例,也希望请教一下各位专家,在妊娠条件下,卵巢肿瘤的诊断是不是要适当退一退,不要过诊断?有无研究资料介绍妊娠与肿瘤的关系? 谢谢! 非常感谢您的参与,能否把您的病例发到网上一起讨论,谢谢! |

and the frequency and features carcinomas developed on these benign tumours are
little known.Eight-hundred and forty-five epithelial tumours of the ovary
diagnosed over a 10-year period have been re-examined. One-hundred and eighteen
adenofibromas and cyst-adenofibromas were recorded. One-hundred were benign and
formed an architectural spectrum from which emerged: (1)surface papillary
adenofibroma accounting for 5% of the cases and appearing at a mean age of 27
years; (2) cystadenofibroma in 77.5% of the cases at a mean age of 53
years; (3)adenofibroma in 17.5% of the cases at a mean age of 64 years.
Adenofibroma was bilateral in 18 cases. Among the other cases were an
endometrioid cyst and two simple serous cysts. The cells were serous in 110
cases, mucinous in 6 cases and weakly acidophilic to clear in 2 cases. Eighteen
of these tumours were malignant:13 were associated with epithelial hyperplasia
and 5 with a carcinoma. The 13 adenofibromas with atypical epithelial
hyperplasia (at a mean age of 60 years) were all made of serous cells; 6 of
them were low-grade and 7 high-grade tumours with 3 microinvasions. One patient
died at the age of 78, of an unknown cause; the others are still alive after a
mean follow-up of 11.3 years. The 5 invasive carcinomas appeared on an
adenofibroma at the mean age of 70 years; 3 patients died (2 of metastases),
one is alive after 9 years and one was loss sight of.

今天看到金老师的病例,也希望请教一下各位专家,在妊娠条件下,卵巢肿瘤的诊断是不是要适当退一退,不要过诊断?有无研究资料介绍妊娠与肿瘤的关系?
谢谢!今天我把病例图片发到网上,请金老师和各路高手帮我看看,谢谢!
卵巢病理恐怕是人体器官病理最复杂的。交界性浆液性肿瘤又是争论最大的, 连名字都有3个。
左侧卵巢前后2次的病理不同可以用同一个肿瘤不同部位来解析,因为很多交界性肿瘤往往还有腺瘤成分(二者比例多少视肿瘤生长时期而定,只要大于10%的地方是交界性就可以把整个肿瘤叫做交界性肿瘤),所以第一次取材取得是交界性的地方,第二次取材的是腺瘤的地方)。
这个病人发现肿瘤是怀孕的, 孕激素对交界性浆液性肿瘤肯定是有影响的,否则不会出现孕期的浆液性交界性肿瘤的微小浸润的比例是非孕期的8-9倍。但是到底怎么个影响法,我想目前知道太少。是否会出现孕激素退了以后,肿瘤也退化呢(缺乏生产激素?)?不知道,目前也没有这方面的报道, 没有报道不等于不存在。
不知道是否有大网膜和腹膜的前后2次的病理学的对比? 这个病例的病理学的对比可能需要全面的对比, 否则不能排除取材的因素。
