IntroductionEctopic prostatic tissue is prostatic tissue located distant from the prostate gland. Although its existence is not uncommon, the occurrence of adenocarcinoma in ectopic prostatic tissue is rare.Case presentationA 68‐year‐old man was suspected to have a nodular‐type tumor in the bladder trigone and a tumor in the prostate based on magnetic resonance imaging and cystoscopy results. Transurethral tumor resection and transrectal prostate needle biopsy revealed the coexistence of ectopic prostatic adenocarcinoma in the bladder trigone and low‐risk orthotopic prostate cancer. Four years later, the tumor evolved to intermediate‐risk prostate cancer during active surveillance, and the patient underwent prostatectomy with resection of the bladder trigone. Pathology indicated no residual ectopic prostatic tissue or adenocarcinoma at the bladder trigone.ConclusionAdenocarcinoma in ectopic prostatic tissue is very rare; however, when found, the possibility of concurrent cancer in the prostate gland should be considered.
We present a case in a 74-year-old female patient whose initial symptom was right flank pain. Enhanced computed tomography showed a mass (about 15×12 cm) in the retroperitoneum, inferior vena cava tumor thrombus (Level III: Neves and Zincke system) and liver metastasis. The primary tumor exploded and inferior vena cava tumor thrombus caused congestive liver one and a half month later. Preoperative diagnosis was right adrenocortical carcinoma (cT4N0 M1 stage IV). We performed complete resection of tumor including metastasis. Pathological findings on the resected specimen revealed pleomorphic leiomyosarcoma, which was discontinuous tumor from the right normal adrenal grand. There was no evidence of local recurrence or metastasis after 6 months with no additional treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
