Serous papillary cystic tumor of borderline malignancy with focal carcinoma arising in testis: Case report with immunohistochemical and ultrastructural observations

Ovarian Type Surface Epithelial Carcinoma of the Testis with Delayed Metastatic Spread

“…These tumors occur in an older age group than other testicular carcinomas with a median age of 64 years [1] . Patients most commonly present with painless scrotal enlargement, sometimes in association with a hydrocele [2][3][4][5] .…”

“…Secondary müllerian tumors develop by metaplasia from the mesothelium of the tunica vaginalis corresponding to the female pelvic mesothelium which in part forms the covering epithelium of the ovaries. These tumors include the testicular tumors of ovarian type surface with mucinous, serous and other subtypes [1,[3][4][5] .…”

“…The localized presentation of the overwhelming majority of the reported cases gives the impression of a favorable clinical outcome [3,5] . However, the malignant potential with a tendency to later metastatic spread as illustrated by this case should be taken into consideration.…”

Papillary serous carcinoma of the peritoneum in a man

“…4 It is recognized as a distinct clinicopathologic tumor that arises from mesothelial cells under Mü lle-PSCO in the male peritoneum, including rare lesions involving the tunica vaginalis testis, and epididymis. 7,8 rian influences.…”

Selected other problematic testicular and paratesticular lesions: rete testis neoplasms and pseudotumors, mesothelial lesions and secondary tumors

“…1,13,14,16 Microinvasion (using ovarian criteria) may infrequently be seen in borderline tumors, however, one such case has been clinically malignant, indicating that ovarian criteria may not be appropriate in this region and further experience with this form of serous neoplasia, and for that matter other forms, is required before any firm conclusions concerning prognostic criteria can be made. 19 Generous sampling and continued clinical surveillance are thus required for all borderline tumors. The prognosis is usually excellent for completely excised borderline serous tumors.…”
