Herein we present a previously unreported rare case of mucinous adenocarcinoma arising from a congenital ejaculatory duct cyst. Radiographic and endoscopic examinations revealed the tumor occurred in a cyst running through the prostate. Initially, the immunohistochemical pathology results showed that it was a metastatic mucinous adenocarcinoma, but no other primary lesions were clinically evidenced. Based on the embryonic development process of the male urogenital tract, the malformation of the patient's ejaculatory duct, and the pathological examination of the resected specimen, we considered the tumor to be a primary mucinous adenocarcinoma which originating from the hypoplastic ejaculatory duct. The tumor may have developed from the foci of intestinal metaplasia from cloacal remnants during embryonic development.

There have been no reports of ruptured solid pseudopapillary neoplasm (SPN) into adjacent organs. A 22-year-old female was referred to our hospital for treatment of a pancreatic head tumor. Computed tomography (CT) examination at our hospital showed a 5-cm tumor containing air, although CT at a previous hospital revealed an 8-cm tumor without air. Thus, a spontaneous rupture of the tumor into the duodenum was suspected. Subtotal stomach preserving pancreaticoduodenectomy with combined resection of the portal vein was performed. Contrast radiography of resected specimen showed the medium injected into the tumor leaking out from the 2nd portion of the duodenum. Histologically, the patient was diagnosed as SPN. Microscopic invasion to the portal vein and duodenum were also confirmed. She did not experience any postoperative complications and has remained well without any signs of recurrence during 2 years of follow-up. Although there have been 14 studies reporting ruptured SPN, this is the first report of SPN that spontaneously ruptured into the duodenum. An extremely rare case of SPN of the pancreatic head that spontaneously ruptured into the duodenum was reported.

CONTEXT: Primary adenocarcinomas of the bladder are uncommon and usually occur by contiguity with or hematogenic dissemination of other adenocarcinomas such as colorectal, prostate and gynecological tract carcinomas. Mucinous and signet-ring cell histological patterns are even rarer and it is often difficult to morphologically distinguish them from metastatic colorectal adenocarcinoma. CASE REPORT: We present and discuss a rare case of primary mucinous adenocarcinoma of the bladder with signet-ring cells in a 57-year-old male patient. Other primary sites for the tumor had been excluded and, in the absence of digestive tract tumor and for confirmation that it was a primary bladder tumor, an immunohistochemistry study was performed.

Hemangioma are rare tumor originating from the pericytes, the contractile cells that surround capillaries. This tumor arises from pericapillary cells or pericytes of Zimmerman and can occur anywhere where capillaries are found . Howeverhemangiopericytoma develops mainly in the lower extremities, retroperitoneum or pelvis. The recommended treatment for a hemangiopericytoma is wide excision. Since many benign and malignant diseases occur in the area surrounding the anus, recognizing the presence of this malignant tumor in the presacral space is important in order to avoid inappropriate surgery such as piecemeal excision. We describe a rare case of a hemangiopericytoma in the presacral space. With posterior approach the tumour was completely removed. Pathological examination includingimmunohistologicalstains was consistent with a hemangiopericytoma.

Background: Renal agenesis is a congenital malformation that occurs due to the inhibition of metanephric blastema induction due to a decrease in ureteric bud activity. Although renal agenesis is not very rare, unilateral renal agenesis with ureterocele occurs rarely, and the coexistance of unilateral renal agenesis, ureterocele, and blind ended proximal ureter is very rare. Recently, we experienced a case of left renal agenesis with huge ureterocele, blind ended proximal ureter, and duplicated ureter on Computed tomography (CT) of a 17-year-old man who visited our emergency department with hematuria. Ureterocelectomy and nephrectomy were performed, and a translocation of seminal vesicle was also observed. This case is a very rare case, so we judged that it may be helpful in making treatment decisions in similar cases later. Case summary: A 17-year-old man without specific medical history visited our emergency department with hematuria and voiding difficulty. CT showed left ectopic kidney, megaureter and the blind ended proximal ureter. After ureterocelectomy and nephrectomy, pathological examination revealed seminal vesicles in the periphery of the kidney. After one year, the patient has no complications and no complaining symptoms complaints without any abnormal finding of follow up imaging test. Conclusions: This case report focuses on the treatment of renal agenesis with ureterocele, blind ended proximal ureter, duplicated megaureter and translocation of seminal vesicle. This rare case of treatment will be helpful in the determination of treatment for similar cases in the future. To establish standard treatment, data accumulation and well-designed studies are required.
