“…Most cases were asymptomatic, with one presenting hematuria, however, the patient presented concomitant bladder cancer, and whether the symptom was due to the ETP adenocarcinoma was unclear. Four of the cases were accompanied by prostate gland adenocarcinoma, as in this case 2–4,6 . One case revealed no malignancy in the prostate gland in a prostatic biopsy 5 ; the last case had no prostate gland examination performed 7 .…”

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.

Background Ectopic prostatic tissue is a relatively infrequent condition, usually found accidentally during imaging examinations or surgery. From 1967 to 2021, the reports of ectopic prostate tissue in English literature are increasing. It is rarely reported that ectopic prostate may be misdiagnosed as a nephrogenic adenoma (NA). Case presentationThis article reports a 45-year-old male patient with no symptoms. The computed tomography (CT) scan revealed a homogeneous isoechoic mass in the posterior inferior wall of the bladder. Firstly, the transurethral cystoscopic biopsy revealed a smooth sessile mass that covered normal bladder mucosa located in the middle of the interureteric ridge, and pathological results considered an intravesical NA. Then, the mass was completely resected under laparoscopic pneumovesicum and the pathological diagnosis was ectopic prostate tissue. Conclusions The clinical symptoms of ectopic prostate were similar to other bladder neoplasms, and fewer characteristics of imaging examinations are available to diagnose. Surgery was the mainstay treatment of ectopic prostatic tissue and has a good prognosis. Ectopic prostatic tissue presents as a tumor in the bladder, urologists may easily misdiagnose the condition like a tumor. Therefore, it is necessary to awareness of ectopic prostatic tissue to avoid misdiagnosis.

“…Although the postoperative prognosis is good, ectopic prostatic tissue may be recurrent [10], but no malignant cases of recurrent ectopic prostatic tissue seem to have been reported. However, the development of cancer in the ectopic prostatic tissue of the bladder has been reported [11], and therefore, regular examinations and follow-ups are crucial for patients with this condition.…”

Ectopic prostatic tissue is rare, and it is usually only discovered by chance during imaging examinations or surgery. However, between 1967 and 2021, reports of ectopic prostatic tissue in the medical literature increased. It is rarely reported that ectopic prostatic tissue can be misdiagnosed as a nephrogenic adenoma (NA). This case study aimed to increase the awareness of ectopic prostatic tissue to improve its rates of diagnosis. This paper is focused on a 45-year-old male patient with a history of bladder lesions that were accidentally discovered through a health examination. A computed tomography scan revealed a homogeneous isoechoic mass in the posterior inferior wall of the bladder. At first, a transurethral cystoscopy revealed a smooth sessile mass covering the normal bladder mucosa, which was located in the middle of the interureteric ridge. The biopsy results suggested a possible intravesical NA. The mass was then completely resected under pneumovesicoscopy, and the pathological diagnosis was ectopic prostatic tissue. The clinical symptoms of ectopic prostatic tissue are similar to other bladder neoplasms, but there are too few characteristics available in imaging examinations to allow for an accurate diagnosis. Since ectopic prostatic tissue can present as a tumor in the bladder, urologists may easily misdiagnose the condition. Surgery is the basis of treatment for ectopic prostatic tissue, and it has a good prognosis.
