Brenner tumor

Brenner tumours very rarely can occur in other locations, including testis.

It has been suggested that these cell rests are the histogenetic origins of Brenner tumors.

Borderline and malignant Brenner tumours are possible but each are rare.

Brenner tumors may be benign or malignant, depending on whether the tumor cells invade the surrounding tissue.

Brenner tumors are uncommon tumours that are part of the surface epithelial-stromal tumor group of ovarian neoplasms.

Epithelial tumors (65-75%) - serous or mucinous cystadenoma/carcinoma, clear cell carcinoma, Brenner tumor 2.

Also, it has been proposed that Brenner tumors and Walthard cell rests signify urothelial differentiation within the female genital tract.

Due to the histological similarity of the epithelium of Walthard cell rests and Brenner tumors to the urothelium of the lower urinary tract.

Brenner tumors are uncommon surface-epithelial stromal cell tumors in which the epithelial cell (which defines these tumors) is a transitional cell.

It is in the transistional cell category of ovarian tumours which also includes malignant Brenner tumour and benign Brenner tumour.

Transitional cell carcinoma is an even rarer entity, in which neoplastic transitional epithelial cells similar to transitional cell carcinoma of the bladder are seen in the ovary, without the characteristic stromal/epithelial pattern of a Brenner tumour.

Not to be confused with Meige syndrome In medicine, Meigs syndrome, also Meigs' syndrome, is the triad of ascites, pleural effusion and benign ovarian tumor (fibroma, Brenner tumour and occasionally granulosa cell tumour).
