①Brenner tumour

Brenner瘤

Definition

Brenner tumour is a tumour composed of nests of bland transitional/urothelial epithelium set within a dense fibromatousstroma.

定義

Brenner瘤是一種由溫和的移行上皮/尿路上皮細胞巢組成的腫瘤，位于致密的纖維瘤性間質(zhì)中。

ICD-O coding

9000/0 Brenner tumour NOS

ICD-O編碼

9000/0 Brenner瘤NOS

Essential and desirable diagnostic criteria

Essential: tumours with nests of bland transitional/urothelial epithelium set within fibromatous stroma.

必需和理想的診斷標準

必需:形態(tài)溫和的移行/尿路上皮細胞巢位于纖維瘤性間質(zhì)中。

Fig. 1.59 Brenner tumour. A Transitional/urothelial nests (some of which show cyst formation) are in a fibromatous stroma. B Characteristic cytological features include uniform oval cells with pale cytoplasm, nuclei with occasional grooves, fine chromatin, and small nucleoli.

圖1.59 Brenner瘤。A移行/尿路上皮巢(其中部分有囊腔形成)位于纖維瘤性間質(zhì)中。B細胞學特征包括一致的卵圓形細胞，胞質(zhì)淡染，偶有核溝，染色質(zhì)細，核仁小。

②Borderline Brenner tumour

交界性Brenner瘤

Definition

Borderline Brenner tumour is a tumour of transitional/urothelial epithelium displaying papillary architecture and lacking stromal invasion.

定義

交界性Brenner瘤是一種移行/尿路上皮腫瘤，呈現(xiàn)乳頭狀結(jié)構(gòu)，缺乏間質(zhì)浸潤。

ICD-O coding

9000/1 Brenner tumour, borderline malignancy

ICD-O編碼

9000/1Brenner瘤，交界性惡性腫瘤

Essential and desirable diagnostic criteria

Essential: papillary growth resembling low-grade papillary urothelial neoplasms of the urothelial tract or (rarely) crowded nests of transitional/urothelial epithelium, without stromal invasion.

Desirable: a benign Brenner component.

必需和理想的診斷標準

基本特征:乳頭狀生長，類似于尿路低級別乳頭狀尿路上皮腫瘤，或(罕見)擁擠的移行/尿路上皮巢，無間質(zhì)浸潤。

理想的:良性Brenner瘤成分。

Fig. 1.61 Borderline Brenner tumour. A This tumour shows an endophytic, ribbon-like growth pattern. B Cytologically, this tumour shows uniform transitional-type epithelium.

圖1.61交界性Brenner瘤。A腫瘤顯示內(nèi)生性、帶狀生長模式。B細胞學上，該腫瘤顯示一致的移行上皮。

③Malignant Brenner tumour

惡性Brenner瘤

Definition

Malignant Brenner tumour is anovariancarcinoma resembling an invasive urothelial carcinoma, associated with benign or borderline Brenner tumour.

定義

惡性Brenner瘤是一種類似于浸潤性尿路上皮癌的卵巢癌，與良性或交界性Brenner瘤相關(guān)。

ICD-O coding

9000/3 Brenner tumour, malignant

ICD-O編碼

9000/3 Brenner瘤，惡性

Essential and desirable diagnostic criteria

Essential: Malignant tumour with urothelial differentiation; a benign or borderline Brenner tumour component in the background.

必需和理想的診斷標準

必需：惡性腫瘤伴尿路上皮分化;背景中有良性或交界性Brenner瘤成分。

B Confluent sheets of tumour with solid growth and pseudoglandular structures. C GATA3 is positive in the esidual benign component but lost in the malignant Brenner tumour.

圖1.62惡性Brenner瘤。A腫瘤呈實性融合和乳頭狀生長，下方有良性Brenner瘤殘余。B腫瘤融合成片，實性生長和假腺樣結(jié)構(gòu)。C GATA3在殘余的良性腫瘤中呈陽性，但在惡性Brenner瘤中呈陰性。
