Unlike bilateral tubal ligation, which has a greater protective risk of endometrioid and clear-cell carcinoma of the ovary, bilateral salpingectomy appears to further reduce risk of serous carcinoma of the ovaries as well.
Fertility-sparing surgery in patients with clear-cell carcinoma of the ovary: is it possible?
We suggest that clear-cell carcinoma RCC should be included as a distinct tumor diagnosis, as the phenotype presents clear-cell morphology without evidence of a primary kidney tumor.
A 55-year-old man presented eight years after partial nephrectomy for clear-cell carcinoma of the left kidney with multiple bilateral pulmonary nodules, low left renal nodules, and a soft tissue lesion in the right orbit.
YSTs can show variable presentation under a microscope, and pathologists may have difficulty in differentiating microcystic or endodermal sinus-like structures from clear-cell carcinoma.[sup][3] Indeed, our patient was diagnosed initially with suspected clear-cell carcinoma, and the presence of a YST was determined postoperatively.
In another study, RCC of the native kidney in the context of a renal transplant was found to have an incidence within 0.35%-3.9%, with histologies consisting primarily of clear-cell carcinoma and papillary renal cell carcinoma [10].
Histopathology report demonstrated a metastatic lesion of renal clear-cell carcinoma with dimensions of 70 mm x 50 mm x 50 mm, paratubal cyst, and hyperemia (Figure 3).
Postoperative pathological examination confirmed advanced clear-cell carcinoma (pT4N0M0 Fuhrman grade II).
described adenocarcinoma, adenoacanthoma, adenosquamous carcinoma, clear-cell carcinoma, and papillary serous carcinoma in 60%, 22%, 7%, 6%, and 5% of the cases [22].
A phase II study of the cancer vaccine TG4010 alone and in combination with cytokines in patients with metastatic renal clear-cell carcinoma: clinical and immunological findings.

Duration of breastfeeding did not affect the overall risk of epithelial ovarian cancer, although the risk of clear-cell carcinoma (a relatively rare type of ovarian tumor) was substantially reduced among women who breastfed for at least six months (0.2).
