IHC results:
Positive:AE1/AE3、EMA、CK7、LeuM1、AFP、Hepar-1
Negative:Vim、α-inhibin、Calretinin、CD10、CD99、HMB45、S100、A103ER、AR、WT1、 PAX8、HNF1β、CgA、HCG、CEA
Discussion:(讨论)
1、Rare primary ovarian carcinoma. 2、Introduced by Ishikura and Scully in 1987 3、occurs almost exclusively in postmenopausal famales
4、Elevation of serum AFP and serum CA125 5、Most of the hepatoid carcinoma cases were clinically advanced tumors 6、large, polygonal, round or oval cells, abundant amounts of eosinophilic cytoplasm, distinct cell borders resembling hepatocellular carcinoma 7、Arranged in sheets, trabecular pattern 8、May combine with other surface epithelial carcinomas, sex cord stromal tumor 9、Metastasis to lymph node, spleen, liver, lung, soft tissue, etc. 10、most likely a variant of common epithelial carcinoma by a process of neometaplasia or transdifferentiation
(• 罕见的原发性卵巢癌 •Ishikura 和 Scully 在 1987年首次介绍 • 几乎总是发生于绝经后妇女 • 血清AFP和血清 CA125都升高• 大多数肝样癌病例为临床晚期 • 细胞大、多角形、圆形或卵圆形,胞质丰富、嗜酸性,细胞边界清楚,类似肝细胞癌 • 排列成片状、小梁状结构 • 可合并其他表面上皮癌、性索-间质肿瘤 • 转移到淋巴结、脾、肝、肺、软组织等 • 很可能是普通上皮癌的一种亚型,发生了肿瘤性化生或转分化)
Differentiated diagnosis(鉴别诊断)
1、Steroid cell tumor 2、Clear cell adenocarcinoma 3、HCC metastasis 4、Hepatoid Yolk sac tumor
(类固醇细胞瘤 、 透明细胞 腺癌、 HCC 转移 、 肝样卵黄囊瘤)
Steroid cell tumor (lipid cell tumor) 类固醇细胞肿瘤 (脂质细胞肿瘤)
(1、average age 43 (2-80) years 2、average size 8.4cm, well circulmscribed, lobulated or multinodular, solid, yellow to brown 3、diffuse or cords pattern, >90% unilateral 4、medium to large cells with distinct cell membranes 5、granular eosinophilic or vacuolated cytoplasm 6、round and centrally placed nucleus with single nucleolus 7、frequently no cytologic atypia and <2 mictoses/10HPF 8、a delicate fibrovascluar stroma 9、malignant: 43%, >2 mitoses/10HPF, 10、necrosis, >7cm, hemorrahage, high-grade nuclear atypia )(平均 年龄 43 (2-80) 岁;平均 大小 8.4cm,边界清楚,分叶状或多结节状,实性,黄色到褐色;弥漫或条索状结构,>90%为单侧性;中-大细胞,细胞膜清楚;颗粒性嗜酸性胞质或空泡状胞质;核圆形,中位,有单个核仁;通常没有细胞学异型性,核分裂<2/10HPF;纤细的纤维间质;恶性: 43%, 核分裂>2/10HPF, 坏死, >7cm,出血, 高度核异型性)
IHC features;(免疫组化特征)
1、Inhibin and calretinin + 2、A103, CD10, CD56 and vimentin frequently + 3、S100 and HMB45 + in some cases
4、Some tumors may stain for CK or CD99
(Inhibin+,calretinin +、 A103, CD10, CD56 和 vimentin 通常 +、部分病例S100 +和 HMB45 +、部分肿瘤表达CK 或 CD99)
HCC metastasis
1、high risk of HCC: chronic hepatitis B or hepatitis C infection, liver cirrhosis 2、in china, young patients with HBV+
3、Liver lesions 4、Bilateral ovary 5、bile ductal differentiation 6、IHC: CK7-, EMA-,Hepar-1+, Arg+, AFP+
(HCC 转移:HCC高危因素:慢性乙肝或丙肝,肝硬化;中国,年轻患者伴HBV+;肝脏发现疾病;累及双侧卵巢;肝细胞分化;免疫组化: CK7-, EMA-,Hepar-1+, Arg+, AFP+)
Clear cell adenocarcinoma
1、Solid pattern, always show other architectural patterns, tubulocystic, glandular and papillary, hobnail cells are common 2、Clear or eosinophilic cytoplasm 3、Adenofibromatous background and/or endometriosis 4、IHC: PAX8+, HNF1β+, AFP-, Hepar-1-
(透明细胞 腺癌:实体型,通常显示其他结构:管囊型、腺体和乳头,常见靴钉细胞;透明或嗜酸性胞质;腺纤维瘤背景和/或子宫内膜异位症;免疫组化: PAX8+, HNF1β+, AFP-, Hepar-1-)
Yolk sac tumor (Hepatoid and solid pattern)
1、Mostly young (<20 yrs) 2、The most common is reticular and microcystic pattern 3、Pseudopapillary, hepatoid, glandular patterns 4、Solid pattern, may predominate in recurrences 5、Primitive cells display nuclei with prominent nucleoli and brisk mitotic activity
(卵黄囊瘤 (肝样和实性结构):大多数年轻 (<20 yrs);最常见网状和微囊结构;假乳头、肝样和腺样结构;复发时可能主要为实性结构;原始细胞,核仁明显,核分裂活跃)
