“…The remaining 5% are found in unusual sites (6) that very rarely include the prostate (21), the testis (2) the urethra (28) and, in approximately 31 reported cases, including the present, the kidney (1, 3-5, 7-12, 14-20, 22, 24-27, 29-31). In cases of renal carcinoid, the male female ratio appears equal and age at diagnosis varies from 12 to 79 years (mean 48 years; median 53 years).…”

A case of renal carcinoid tumour arising within a teratoma in a horseshoe kidney in a 23-year-old male is reported. The presenting symptom was abdominal pain, and bone tissue within the tumour was initially misinterpreted as a calyx stone, leading to unsuccessful attempts at extracorporeal shock-wave lithotripsia and percutaneous lithotripsia. This unusual tumour is over-represented in patients with horseshoe kidney and other congenital developmental renal defects.

“…A carcinoid tumor develops sporadically in various organs such as liver, kidney and ovaries, although it is usually discovered in the bronchus and digestive tract. A carcinoid tumor developing in the urethra is very rare, and there have only been two reports of this to our knowledge 1,2 . We report here the first case of urethral typical carcinoid tumor found in a Japanese woman.…”

We experienced an extremely rare tumor in the female urethral orifice in a 57-year-old Japanese woman. To our knowledge, only two cases of primary urethral carcinoid tumor have been reported. The previous reports of urethral carcinoid tumor were recognized in the male middle urethra and penile urethra. The present case was resected, and diagnosed as a carcinoid tumor by histological, immunohistochemical and ultrastructural findings. The tumor cells were stained by chromogranin A, synaptophsin and neuron-specific enolase, and neurosecretory granules were confirmed with electron microscopy. The patient did not complain of any symptoms until 5 years after the resection of the tumor. Therefore, the case we describe here is the first known report of carcinoid tumor in the Japanese female urethra.

“…Using Pubmed and the search words "urethra" and "carcinoid" only four articles are found, each reporting a single additional case of a urethral carcinoid tumor [1-4]. The first case of urethral carcinoid, reported by Sylora et al in 1975, involved an 8 mm lesion of the penile urethra in a 47-year-old man.…”

Carcinoid tumor of the verumontanum (colliculus seminalis) of the prostatic urethra with a coexisting prostatic adenocarcinoma: a case report

et al. 2010

IntroductionUrethral carcinoid tumors are very rare tumors with only four cases described in the literature.Case presentationWe present the case of a 61-year-old man with a primary carcinoid tumor of the verumontanum (colliculis seminalis) portion of the prostatic urethra with a coexisting prostatic adenocarcinoma. In addition to whole mount hematoxylin and eosin staining, special immunoperoxidase staining specific for chromogranin A, neuron specific enolase, synaptophysin, pan-cytokeratin and PSA, and a special combined staining for racemase (α-methyl CoA) antigen and p63 antigen were performed. A review of the literature is included.A single focus of invasive prostatic adenocarcinoma was identified in the periphery of the mid-left, posterior quadrant of the prostate. Approximately 17 mm from this adenocarcinoma, within the verumontanum of the prostatic urethra, there was a 3 mm maximal dimension carcinoid tumor.ConclusionBased on different histological features and antigenic profiles, we concluded that the two tumors were distinct.

Primary Carcinoid Tumor of the Urethra

Abstract: The first reported case of a carcinoid tumor of the urinary tract is presented. Because of rapid local recurrence and distant spread early radical surgery is recommended. Several methods of palliation of the carcinoid syndrome-surgical, pharmacologic and chemotherapeutic-are discussed.
