Germ cell tumors (GCTs) comprise a heterogeneous group of tumors in terms of histology, age at diagnosis, anatomical site and prognosis. Here we describe the epidemiology of GCT on the basis of data from European population-based cancer registries (CRs) analysed in the framework of the EUROCARE (European Cancer Registrybased study on survival and care of cancer patients) project, which has moni...
Between 2 and 5% of malignant germ cell tumors in males arise at extragonadal sites. The origin of extragonadal retroperitoneal germ cell tumors remains controversial. Whether these develop primarily in the retroperitoneum or are metastases of a primary testicular tumor has long been debated. We report a 38-year-old male who presented with abdominal pain and was diagnosed with retroperitoneal s...
Mediastinal germ cell tumors are rare malignant tumors whose current management strategy involves making a prompt diagnosis and providing an appropriate chemotherapy. However, there is as yet no consensus regarding the optimal management postchemotherapy. We encountered the case of a 23-year-old man who was diagnosed as having a mediastinal nonseminomatous germ cell tumor. We evaluated its resp...
The most frequent ovarian germ cell tumors are mature cystic teratomas (MCTs), composing 10-25% of all ovarian neoplasms. MCTs have the potential of undergoing malignant transformation, typically in postmenopausal women, with a frequency of 0.17-3%, with squamous cell carcinoma being the most common malignant tumor arising from MCT. We present the rare clinical entity of a squamous cell carcino...
The pineal region can be affected by different types of lesions, ranging from benign masses (e.g. pineal cysts) to highly malignant tumors. These neoplasms are typical of the pediatric age, while they are rarer in adults. Due to the extreme heterogeneity of the cell types of the pineal gland and its surrounding structures, these tumors include several entities, namely germ cell tumors (GCTs), w...
Galectin-3, a beta-galactoside-binding lectin, has been implicated in many human malignancies, but has seldom been studied in human gonads and gonadal tumors. The aim of our study was to investigate galectin-3 mRNA and protein expression in normal ovaries and testes as well as in a variety of 51 gonadal sex cord stromal and germ cell tumors, and two testicular seminomatous and non-seminomatous ...
Testicular germ cell tumors (TGCTs) are the most common solid tumors in young adult men characterized by distinct biologic features and clinical behavior. Both genetic predispositions and environmental factors probably play a substantial role in their etiology. TGTCs arise from a malignant transformation of primordial germ cells in a process that starts prenatally, is often associated with a ce...
