Primary adenocarcinoma of the rete testis is a rare malignant testicular tumor with a poor prognosis. Here we report the case of a 54-year-old man with right hydronephrosis that was detected before the diagnosis of the primary testicular lesion. During the evaluation of the right hydronephrosis by use of abdominopelvic computed tomography, a painless, hard, solid lesion was found on the right t...
We report a case of 33-year-old man who initially presented with upper gastrointestinal bleeding caused by metastatic testicular cancer. Physical examination was significant for a palpable abdominal mass. Emergency gastroduodenoscopy yielded an ulcerated infiltrating mass in the third portion of the duodenum. Computerized tomography of the abdomen demonstrated a retroperitoneal mass. Histologic...
Serological analysis of recombinant cDNA expression libraries (SEREX) has led to the identification of several categories of new tumor antigens. We analyzed a testicular cDNA expression library with serum obtained from a breast cancer patient and isolated 13 genes designated NW-BR-1 through NW-BR-13. Of these, 3 showed tumorrestricted expression (NW-BR-1, -2 and -3), the others being expressed ...
BACKGROUND Testicular germ cell tumors (TGCT) are the most common cancer entities in young men with increasing incidence observed in the last decades. For therapeutic management it is important, that TGCT are divided into several histological subtypes. MED15 is part of the multiprotein Mediator complex which presents an integrative hub for transcriptional regulation and is known to be deregulat...
Despite the overall cure rate now in excess of 90%, innovation in management of germ cell tumors continues. The report that 80% of patients with extragonadal germ cell tumors have either carcinoma in situ or atrophic tubules as evidence of tumor rejection emphasizes the need to investigate the testis in patients with undiagnosed primary cancer because even today treatment delay is worsening pro...
BACKGROUND Granulosa cell tumor of the testis is a rare intermediate stromal cell tumor that can be distinguished in the adult and juvenile type. The juvenile type is the most common reason for scrotal swelling in newborns under the age of six months. Less than fifty cases of this disease entity have been reported in the literature. PATIENTS AND METHODS In the following article, two newborn p...
Cryptorchidism, or maldescended testis, is a common problem encountered in pediatric age groups. Despite more than 100 years of research, many aspects of cryptorchidism are not well defined and remain controversial. However, cryptorchidism clearly has deleterious effects on the testis over time.(1-4)Among the problems associated with an undescended testis are an increased risk for testicular tu...
We report here a case of sclerosing Sertoli cell tumor of the testis. A 21-year-old male, who complained of right testicular pain, visited a Jikei University affiliated hospital on May 30th, 1999. A small nodule with a diameter of 6 to 7 mm was palpable on the central surface of the right testis. No tumor markers for testicular cancer, such as hCG-beta and alfa-fetoprotein, were elevated. Howev...
The current study aimed to evaluate the efficacy of simultaneous administration Zingiber officinale (ginger) and Cinnamomum cassia (cinnamon) extracts in mitigating testicular changes associated with diabetes mellitus rats investigate its molecular mode action. After induction using streptozotocin, 36 male were divided six groups namely control, diabetic, metformin-treated, cinnamon-treated, gi...
Yolk sac tumor is the most common tumor of testis in children below 3 years. Most of these tumors present as painless, enlarged testicular masses. They are most frequently associated with elevated alpha fetoprotein (AFP) levels. We report a case of yolk sac tumor in an 11 month old child who presented as a painless testicular mass.
