Bilateral inguinal tumors. A. Pelvic CT scan showed bilateral heterogeneous tumors with solid and cystic components (white arrows). B. Gross features of left inguinal mass showed a cystic tumor of para-gonadal tissue and tan-white, firm, and nodular gonad (arrow). C. Histologic features of para-gonadal tumor showed complex hierarchical branching papillae with frequent psamommatous calcification (H&E 40×). D. High-power-field shows papillary lining cells with cytologic atypia (H&E 200×). E. Diffuse nuclear stain for PAX8 of tumor cells (100×). F. Simple serous cysts were seen in para-gonadal tissue (H&E 100×).

We report a case of complete androgen insensitivity syndrome (CAIS) accompanied by serous borderline tumors in a 75-year-old patient. Müllerian epithelial tumors are extremely rare condition in CAIS patients with only a few case reports. We report a case of late-diagnosed testicular feminization with hamartomas, and the first report of serous tumor...

... examination showed a protruding mass at left inguinal area. Further computed tomography (CT) scan revealed bilateral multilocular masses with heterogenous solid and cystic components herniating into the canal of Nuck ( Figure 1A). The left side mass was 19 cm in size, and the right side mass was 7 cm in size. ...

... the left abdominal and inguinal tumor mass showed cystic and solid components with rough surface and focally polypoid inner lining. The bilateral gonads were multinodular, firm, and tan-white in color ( Figure 1B). The majority of tumor mass was located within pelvic cavity and the soft tissue of inguinal canal, only focal surface attachment to the left gonad was seen. ...

... the tumor showed hierarchical, branching papillae, lined by cuboidal to columnar epithelium with only mild nuclear atypia. Numerous psammomatous calcifications were seen within the tumor ( Figure 1C and 1D). The tumor cells showed diffuse nuclear immunostaining for PAX8 ( Figure 1E), supporting the Müllerian origin. ...

Among testicular neoplasms, ovarian-type epithelial tumors constitute an exceedingly rare group, with only a few cases reported in the literature. We describe the case of an 82-year-old man, presented with complaints of right leg pain and difficulty walking, who was found to have a large right tibial metastasis of unknown primary origin. Whole body CT scan did not reveal any cranial, thoracic or abdominal tumor masses, but it showed abnormal para-aortic lymph nodes and right spermatic cord swelling. An extemporary ultrasound examination found a right testicular mass. The patient underwent radical orchiectomy, and the diagnosis of a serous papillary carcinoma of the ovarian epithelial type of the testis was made. To the best of our knowledge, this is the first case in the literature of isolated bone metastasis from ovarian-type epithelial tumor of testis.
