ABSTRACT
Background: Little is known about the prevalence of testicular cancer in the transfeminine population. Only six cases have been reported in the literature. This case series reports six additional cases of various testicular cancers found in transfeminine patients who underwent vaginoplasty with orchidectomy in our institution. Methods: In our institution, all specimens are routinely sent to pathology following vaginoplasty with orchidectomy. This permitted the identification of all positive cases of testicular cancer. A chart review was conducted to retrieve patient demographics, duration of hormonotherapy, type of neoplasm, the context of its discovery, and cancer follow-up. Results: A total of 2555 patients underwent vaginoplasty with orchidectomy between January 2016 and January 2021. All specimens were sent to pathology for analysis. A total of six (0.23% of patients) specimens revealed malignant lesions. Conclusions: Increased societal awareness toward the transgender population encourages recourse to gender-affirming procedures. Little is known about the incidence of testicular cancer in the transfeminine population. In total, 0.23% of patients in our cohort presented with positive pathology findings indicative of testicular cancer. All cancers were found to be only locally invasive, and all patients were successfully treated. We therefore encourage routine pathology examination for all specimens following vaginoplasty with orchidectomy.
