Testicular cancer is a rare disease; however, cure rates are high for all tumor stages. Mostly, the disease diagnosed in an early (local) stage. We report case of 47-year-old male patient with giant nonseminomatous germ cell tumor. At time diagnosis, demonstrated necrotizing and ulcerating growing mass left scrotum approximate size 22 × 18 cm. According to prognostic classification Internationa...

A germ cell tumor is the most common form of malignancy in early male life, and can be classified as either seminomatous or nonseminomatous. Choriocarcinoma, comprised of nonseminomatous germ cells, is the most aggressive type of germ cell tumor and characteristically metastasizes to the retroperitoneal lymph nodes and less frequently to the lungs, liver, bone or brain [Shibuya et al., 2009;48:...

A rare case of synchronous bilateral testicular germ cell tumor of different histological type is described. We report the case of a 39-year-old man with this unusual condition and discuss the value of the histopathological diagnosis in therapy and prognosis. A thorough review of the literature is also presented, and for the first time the precise histological subtype of each reported tumor, as...

Primary intracranial germ cell tumors are rare, representing less than 5% of all central nervous system tumors. Overall, the majority of germ cell tumors are germinomas and approximately one-third are non-germinomatous germ cell tumors (NGGCT), which include teratoma, embryonal carcinoma, yolk sac tumor (endodermal sinus tumor), choriocarcinoma, or mixed malignant germ cell tumor. Germ cell tum...

A huge retroperitoneal tumor with a right orbital mass was detected and proved to be an extragonadal nonseminomatous germ cell tumor on biopsy. BEP chemotherapy caused some regression in orbital mass however no change in retroperitoneal tumor size as well as serum tumor marker levels occurred. Herein, we present a rarely seen entity of extragonadal retroperitoneal nonseminomatous germ cell tumo...

Testis cancer is one of the few solid organ malignancies for which reliable serum tumor markers are available to help guide disease management. Human chorionic gonadotropin, alpha fetoprotein, and lactate dehydrogenase play crucial roles in diagnosis, staging, prognosis, monitoring treatment response, and surveillance of seminomatous and nonseminomatous germ cell tumors. Herein we discuss the c...

Malignant germ cell tumor (GCT) formation is a well-known complication in the management of patients with a disorder of sex development (DSD). DSDs are defined as congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. DSD patients in whom the karyotype - at least at the gonadal level - contains (a part of) the Y chromosome are at increased risk for ne...

INTRODUCTION Recent scientific attention has focused on the role of growth factors in the progression of cancer. HER-2/neu is an epidermal growth factor receptor that is demonstrated to have correlation with poor prognosis of many cancers. This study evaluated the overexpression of HER-2/neu protein and its clinical importance in nonseminomatous germ cell tumors of the testis. MATERIALS AND M...

BACKGROUND An increasing incidence of testis tumors has been noted over the second half of the 20th century. Congenital malformation of the male genitalia, prenatal risk factors, nonspecific and specific exposures in adulthood, and male infertility have all been associated with the etiology of germ cell tumors. METHODS The histologic classification, pathology, and current concepts of testicul...

Seminomas and non-seminomas are distinct categories of germ cell tumors arising from the testicles. This case report describes a rare occurrence testicular tumor exhibiting histologic characteristics seminoma in 39-year-old male patient who simultaneously has an elevated serum alpha-fetoprotein (AFP). The staging this was pT1bNxM0, stage IS. treated with right radical orchiectomy adjuvant chemo...
