ABSTRACT
A Japanese man in his 60s presented with complaints of epigastric pain and weight loss. A gastrointestinal endoscopy revealed multiple gastric ulcers and an irregular mound located on the wall of the lower gastric body along the greater curvature, which was suspected to be cancerous. A biopsy revealed that it was a Group 2 tumor even though the biopsy was repeated 4 times. He was referred to our hospital and 3 biopsies were performed. The final result classified the tumor as Group 4. The patient underwent surgery and the pathological examination revealed an extremely well-differentiated adenocarcinoma( EWDA). An EWDA is characterized by a well-formed mucinous gland with little or no nuclear atypia, which makes preoperative biopsy diagnosis difficult.

A 46-year-old man was admitted to hospital presenting with a lower abdominal mass. The patient's testes were not palpable in the scrotum, and the levels of lactic dehydrogenase, α-fetoprotein and human chorionic gonadotropin were all elevated. Enhanced computed tomography revealed that the lumen of the mass had penetrated the prostate. Pathological analysis of biopsy tissue indicated that the mass was a seminoma. Residual tumor resection was performed after chemotherapy. On histological examination, the lumen proved to be a Mullerian structure. Our diagnosis was an intra-abdominal germ cell tumor and persistent Mullerian duct syndrome.

Primary tumors of the seminal vesicles are extremely rare. There have been 25 reports of this tumor from overseas and most cases are cystadenoma. We report a case of seminal vesicle cystadenoma in a 70-year-old man who presented with lower abdominal pain and urinary frequency. A digital rectal examination detected a projecting and hard mass in the right side of the prostate. Magnetic resonance imaging (MRI) showed a 15 cm multiple cystic mass continuous with the right seminal vesicle. A transrectal needle biopsy revealed benign tissue. The tumor was resected using an open transvesical approach that enabled full exposure of the seminal vesicle without damaging the nerves and blood supply of the bladder. Pathology was consistent with a benign seminal vesicle cystadenoma. We describe the natural history, pathology,and surgical approach in this case.
