本例足以诊断高级别癌了，浆液性乳头状囊腺癌，但部分区似乎有透明细胞腺癌的感觉。不过这两者都属于高级别癌，预后差。

这个应该是直接诊断透明细胞癌。

若考虑浆液性肿瘤只能算交界性浆液性肿瘤伴细胞透明变，这也是本例挑战之处，因为一旦这样诊断就意味着一个诊断是恶性，另外一个诊断是交界性，对病人影响大

本例明显有透明细胞腺纤维瘤样成分，所以那些乳头就是透明细胞癌的证据了，乳头用浆液上皮解释最多够交界，但是用透明细胞源性解释就直接是浸润型透明细胞癌啦。

透明和浆液都可以有乳头和鞋钉结构，胞浆都可以嗜酸性，确实蛮难鉴别的，尤其浆液还可以伴有细胞透明变的时候。

本例乳头区域有明显的玻璃样变性的乳头纤维轴心，这点或许是透明细胞癌与浆液性肿瘤鉴别的一个重要参考点

交界性的透明细胞腺纤维瘤、交界透明细胞腺纤维瘤伴有微浸润以及良性的透明细胞腺纤维瘤都是极其罕见的病例，文献或报道的例子极少或并未有很好建立其标准。

还有：刚开始看还以为是交界性透明细胞腺纤维瘤合并交界性浆液性囊乳头状腺瘤呢！其实一个透明细胞癌可以解释全部形态

APCCT comprise 0.2% of ovarian epithelial tumors (> ). Among approximately 30 cases of APCCT (clear cell adenoﬁbroma of borderlinemalignancy or low malignant potential) in the literature, the mean age is 60–70 years. The mean tumor diameter is about 15 cm.
Microscopically, the architecture is similar to the clear cell adenoﬁbroma, but glands aremore crowded. The tumor has greater epithelial proliferation and atypia than the adenoﬁbroma and lacks stromal invasion. The cell types lining the glands and cystic spaces are similar to those in benign tumors but display signiﬁcant nuclear atypia with coarse chromatin clumping, prominent nucle- oli, and mitotic activity up to 3 per 10 HPF. The epithe- liummay display stratiﬁcation and budding; true papillary structures are uncommon. Small solid nests of clear cells, signiﬁcant gland crowding, or papillary growth should raise the suspicion of stromal invasion. Distinction of an APCCT from clear cell carcinoma is one of the most difﬁcult distinctions in gynecologic pathology. Some clear cell carcinomas lack an obviously inﬁltrative pattern and are characterized solely by crowded glands. The point at which gland crowding in a clear cell neoplasm reﬂects invasion is not well deﬁned. The vast majority of tumors in which this differential is considered are usually classi- ﬁed as clear cell carcinoma. This practice helps ensure comprehensive staging where metastases might be found and thereby conﬁrm a diagnosis of carcinoma. Further- more, it gives the patient the potential beneﬁt of chemo- therapy if there is doubt about the diagnosis.	Occasionally, an endometriotic cyst is lined by atypical epithelial cells with clear cytoplasm. This has been desig- nated ‘‘atypical endometriosis’’ (see>Chap. 13, Diseases of the Peritoneum)[298]. Rarely, cytologic features of malignancy are present in this setting. If the lesion is well sampled and invasion is not found, the lesion is classiﬁed as APCCT with intraepithelial carcinoma. Microinvasion should be diagnosed if invasive areas measure less than 5 mm, but this ﬁnding should prompt additional sam- pling to look for diagnostic features of carcinoma. There are virtually no published data on clear cell tumors with microinvasion or intraepithelial carcinoma, both of which are exceedingly rare. The rarity of clear cell adenoﬁbroma and APCCT could reﬂect the fact that precursors of clear cell carci- noma most often have the morphology of endometriosis with atypia rather than a clear cell neoplasm. Peritoneal ‘‘implants’’ have not been described with APCCTs. Among the limited reported APCCTs, there is one alleged recur- rence and no tumor deaths.
透明细胞癌 Clear cell carcinomas display several different patterns, which often occur together (> – ). These include papillary, tubulocystic, and solid. In a minority of cases, there is a prominent adenoﬁbromatous component [369](> and > ). Recently, some investigators have subdivided clear cell carcinomas into those arising in a cyst and those that have an adenoﬁbromatous background [369]. The cystic tumors are more frequently papillary, whereas the tubulocystic pattern tends to dominate in the adenoﬁbromatous tumors. The cystic variant is more fre- quently associated with endometriosis. In addition, the behavior of the two types of tumors may be different although the data have been conﬂicting [369]. These ﬁnd- ings suggest that the two variants arise along different pathways. The solid pattern of clear cell carcinoma is character- ized by sheets of polyhedral cells with abundant, clear cytoplasm separated by delicate ﬁbrovascular septae or dense ﬁbrotic stroma. The papillary pattern is character- ized by papillae that are either ﬁbrotic but more often are hyalinized (>Figs. 14.116, >14.117, and >14.120). In fact, the hyalinized papillary cores are a very characteristic feature of this tumor. The tubulocystic pattern is charac- terized by varying size tubules and cysts (>Fig. 14.114). The majority of tumors display combinations of all of these patterns [369]. Despite being designated clear cell carcinoma, many of the cells comprising clear cell carci- noma contain slightly granular eosinophilic cytoplasm.

Cystic and adenofibromatous clear cell carcinomas of the ovary: distinctive tumors that differ in their pathogenesis and behavior: a clinicopathologic analysis of 122 cases.

Abstract

Ovarian clear cell carcinomas (CCC) typically present as large adnexal, stage I tumors and are generally considered highly malignant. They are frequently associated with endometriosis and, less often with clear cell adenofibromas. We hypothesized that CCCs are a heterogeneous group of tumors, some arising from a cyst and others from an adenofibroma. To test this hypothesis, 122 cases of CCC were retrieved from the surgical pathology files of National Taiwan University Hospital (74), The Johns Hopkins Hospital (23), and Serei Mikatahara General Hospital (23) (1985 to 2006). Cases were divided into 3 subgroups: (1) cystic, (2) adenofibromatous, and (3) indeterminate. Various features were analyzed including: age, race, laterality, tumor size, architectural pattern (papillary, tubulo-cystic, solid, mixed patterns), grade, mitotic index, association with endometriosis including atypical endometriosis/intraepithelial carcinoma, stage and survival. Nearly 70% of all the patients were diagnosed as stage I. The 2-year and 5-year survival (all stages) was 78% and 68%, respectively. Striking clinicopathologic differences were observed between cystic and adenofibromatous CCCs. Cystic CCC was more frequently diagnosed as stage I compared with adenofibromatous CCC (75% vs. 44%). Conversely, adenofibromatous CCCs were diagnosed more often in advanced stages (stages II-IV) compared with cystic CCCs (56% vs. 18%). Both the cystic and adenofibromatous CCC forms were associated with endometriosis and atypical endometriosis/intraepithelial carcinoma, but the frequency was much higher in the cystic group. Specifically, endometriosis was found in 91% of cystic CCCs and atypical endometriosis/intraepithelial carcinoma in 62% of these cases, whereas endometriosis was found in 44% of adenofibromatous CCCs and atypical endometriosis/intraepithelial carcinoma in 11% of cases. A predominantly papillary pattern was seen in 47% of cystic CCCs, whereas none of the adenofibromatous carcinomas displayed a predominantly papillary pattern. A more favorable outcome was observed for cystic CCCs compared with adenofibromatous CCCs (all stages) which was accounted for by the high proportion of stage I tumors. The 2-year and 5-year survival for the cystic CCCs was 82% and 77% and for the adenofibromatous CCCs (all stages), 62% and 37%, respectively. In summary, subdividing ovarian CCCs into cystic and adenofibromatous CCC reveals differences in a number of clinicopathologic features including their association with endometriosis, histologic patterns, stage distribution, and clinical behavior. Because there were a relatively small number of adenofibromatous CCCs in this series, additional cases must be studied to confirm these findings.

Abstract

We occasionally encountered clear cell adenofibromatous (CCAF) components coexisting in the ovarian clear cell adenocarcinoma (CCA). To reveal the clinicopathologic significance of CCAF components in CCA, we classified 67 cases of surgically resected CCA into CCA with and without CCAF components [CCAF(+) and (-) groups], and compared clinicopathologic parameters, that is, patient age, clinical stage, the degree of optimal cytoreduction, patient outcome, histologic grade and Ki-67 labeling index of the CCA, and the presence of endometriosis, between these 2 groups. Fourteen cases (21%) and 53 cases were classified as CCAF(+) and CCAF(-) groups, respectively. Of these 14 CCAF(+) cases, the CCAF components with atypia were observed adjacent to the CCAF components without atypia in 10, and adjacent to the obvious CCAs in 13 cases. In comparison with the CCAF(-) group, the CCAF(+) group showed a higher frequency of histologically low-grade tumors [93% (13 of 14) vs. 43% (23 of 53), P=0.0027], a lower Ki-67 labeling index (mean 35.9% vs. 44.0%, P=0.0492), and better patient prognosis (5-year survival 78.8% vs. 49.3%, P=0.0277). Endometriosis was much less frequent in the CCAF(+) group than in the CCAF(-) group [14.7% (2 of 14) vs. 67.9% (36 of 53), P=0.00096]. Multivariate analysis identified only optimal cytoreduction as independent favorable prognostic factor. These results suggest that CCAF besides endometriosis is associated with the development of CCA, and that the CCAF(+) group may be a distinct subgroup of CCA with less aggressive biologic behavior.

Pathogenesis of ovarian clear cell adenofibroma, atypical proliferative (borderline) tumor, and carcinoma: clinicopathologic features of tumors with endometriosis or adenofibromatous components support two related pathways of tumor development.

Abstract

The clinicopathologic features of 472 ovarian epithelial clear cell neoplasms (4 adenofibromas [AFs], 41 atypical proliferative [borderline] tumors [APTs], and 427 carcinomas [CAs]) were studied in order to elucidate the morphologic steps involved in the pathogenesis of these tumors and determine whether clear cell CA is a type I or type II tumor in the dualistic model of ovarian carcinogenesis. Thirty-three percent of the CAs had an adenofibromatous background [CA(AF+)], and 67% did not [CA(AF-)]. Endometriosis was found in all types of tumors, but tumors arising in endometriotic cysts were more frequent with CA(AF-)s (p<0.0001). The subset of women with CA(AF-)s with endometriosis were younger (p<0.0001), their tumors were more frequently cystic (p<0.0001), they more commonly had a mixed carcinoma component of non-clear cell type (p=0.006), and they were more frequently oxyphilic (p=0.015) compared with CA(AF+)s. The architecture of the former tumors was more commonly papillary compared to tubulocystic in the latter (p=0.0006). Atypical endometriosis was more common in CA(AF-)s than in AFs, APTs, and CC(AF+)s [p=0.004]. The subset of CA(AF-)s without endometriosis presented more frequently in advanced stage (>I) and were higher grade compared to CA(AF+)s or CA(AF-) with endometriosis (p-values, <0.0001 to 0.0071). All AFs and APTs were stage I compared to 79% of CA(AF+)s. An increase in mean tumor size correlated with each respective tumor category from AF (6.8 cm) to CA(AF+) [12.9 cm]. Notable nuclear atypia was absent in all AFs but was focally present in 27% of APTs and in the adenofibromatous background of 24% of the CA(AF+)s. An increase in the proportion of carcinoma in the CA(AF+)s correlated with an increase in grade and advanced stage. In summary, ovarian clear cell CA appears to develop along two pathways, both of which are related to endometriosis. We speculate that, in one, epithelial atypia arises in an endometriotic cyst and then evolves into clear cell CA, and, in the other, non-cystic endometriosis induces a fibromatous reaction resulting in the formation of AF, which then develops into APT and subsequently a clear cell CA. The absence of endometriosis or adenofibromatous components in CC(AF-)s may be due to overgrowth and obliteration by the invasive carcinoma. Finally, the findings in this study support the view that both types of clear cell CA [CC(AF+) and CC(AF-)] are more closely related to type I tumors.

Abstract

We occasionally encountered clear cell adenofibromatous (CCAF) components coexisting in the ovarian clear cell adenocarcinoma (CCA). To reveal the clinicopathologic significance of CCAF components in CCA, we classified 67 cases of surgically resected CCA into CCA with and without CCAF components [CCAF(+) and (-) groups], and compared clinicopathologic parameters, that is, patient age, clinical stage, the degree of optimal cytoreduction, patient outcome, histologic grade and Ki-67 labeling index of the CCA, and the presence of endometriosis, between these 2 groups. Fourteen cases (21%) and 53 cases were classified as CCAF(+) and CCAF(-) groups, respectively. Of these 14 CCAF(+) cases, the CCAF components with atypia were observed adjacent to the CCAF components without atypia in 10, and adjacent to the obvious CCAs in 13 cases. In comparison with the CCAF(-) group, the CCAF(+) group showed a higher frequency of histologically low-grade tumors [93% (13 of 14) vs. 43% (23 of 53), P=0.0027], a lower Ki-67 labeling index (mean 35.9% vs. 44.0%, P=0.0492), and better patient prognosis (5-year survival 78.8% vs. 49.3%, P=0.0277). Endometriosis was much less frequent in the CCAF(+) group than in the CCAF(-) group [14.7% (2 of 14) vs. 67.9% (36 of 53), P=0.00096]. Multivariate analysis identified only optimal cytoreduction as independent favorable prognostic factor. These results suggest that CCAF besides endometriosis is associated with the development of CCA, and that the CCAF(+) group may be a distinct subgroup of CCA with less aggressive biologic behavior.

Abstract

The clinicopathologic features of 472 ovarian epithelial clear cell neoplasms (4 adenofibromas [AFs], 41 atypical proliferative [borderline] tumors [APTs], and 427 carcinomas [CAs]) were studied in order to elucidate the morphologic steps involved in the pathogenesis of these tumors and determine whether clear cell CA is a type I or type II tumor in the dualistic model of ovarian carcinogenesis. Thirty-three percent of the CAs had an adenofibromatous background [CA(AF+)], and 67% did not [CA(AF-)]. Endometriosis was found in all types of tumors, but tumors arising in endometriotic cysts were more frequent with CA(AF-)s (p<0.0001). The subset of women with CA(AF-)s with endometriosis were younger (p<0.0001), their tumors were more frequently cystic (p<0.0001), they more commonly had a mixed carcinoma component of non-clear cell type (p=0.006), and they were more frequently oxyphilic (p=0.015) compared with CA(AF+)s. The architecture of the former tumors was more commonly papillary compared to tubulocystic in the latter (p=0.0006). Atypical endometriosis was more common in CA(AF-)s than in AFs, APTs, and CC(AF+)s [p=0.004]. The subset of CA(AF-)s without endometriosis presented more frequently in advanced stage (>I) and were higher grade compared to CA(AF+)s or CA(AF-) with endometriosis (p-values, <0.0001 to 0.0071). All AFs and APTs were stage I compared to 79% of CA(AF+)s. An increase in mean tumor size correlated with each respective tumor category from AF (6.8 cm) to CA(AF+) [12.9 cm]. Notable nuclear atypia was absent in all AFs but was focally present in 27% of APTs and in the adenofibromatous background of 24% of the CA(AF+)s. An increase in the proportion of carcinoma in the CA(AF+)s correlated with an increase in grade and advanced stage. In summary, ovarian clear cell CA appears to develop along two pathways, both of which are related to endometriosis. We speculate that, in one, epithelial atypia arises in an endometriotic cyst and then evolves into clear cell CA, and, in the other, non-cystic endometriosis induces a fibromatous reaction resulting in the formation of AF, which then develops into APT and subsequently a clear cell CA. The absence of endometriosis or adenofibromatous components in CC(AF-)s may be due to overgrowth and obliteration by the invasive carcinoma. Finally, the findings in this study support the view that both types of clear cell CA [CC(AF+) and CC(AF-)] are more closely related to type I tumors.

Clear cell carcinomas display several different patterns, include papillary, tubulocystic, and solid. The papillary pattern is characterized by papillae that are either ﬁbrotic but more often are hyalinized. In fact, the hyalinized papillary cores are a very characteristic feature of this tumor. The tubulocystic pattern is characterized by varying size tubules and cysts. The majority of tumors display combinations of all of these patterns.

受各位老师开导，特别是TK1905 老师的精彩文献引用，本人认同卵巢透明细胞癌。
