Pure testicular carcinoid associated with intratubular germ cell neoplasia.
This case report describes for the first time a case of pure testicular carcinoid pre-aortic lymph node metastases in a 25 year old patient with carcinoid syndrome. The simultaneous occurrence of intratubular germ cell neoplasia in the surrounding testicular tissue was identified by OCT4 and placental-like alkaline phosphatase positivity. This confirmed that the tumour had a germ cell origin in...
متن کاملHematologic disorders associated with primary mediastinal nonseminomatous germ cell tumors.
BACKGROUND The association between primary germ cell tumors of the mediastinum (the space between the lung pleura that contains the heart and other chest viscera) and hematologic malignancies has been described by retrospective analysis of patients treated at individual clinical centers. To better characterize the risk of hematologic disorders in patients with extragonadal germ cell tumors and ...
متن کاملOCT4: A sensitive and specific biomarker for intratubular germ cell neoplasia of the testis.
PURPOSE OCT4 (POU5F1, OCT3) immunostaining highlights pluripotent cells (embryonal carcinoma and seminoma) in primary testicular germ cell tumors, but its relative usefulness in diagnosing intratubular germ cell neoplasia, unclassified (IGCNU) is not well established. The present study aimed to establish OCT4 as a sensitive and specific maker for IGCNU, a putative precursor for adult germ cell ...
متن کاملgenetics of testicular germ cell tumors
testicular germ cell tumor (tgct) is the most solid tumor in 20-40 years old man. tgct account for 95% of testicular tumors and represent a unique type of human cancer from several different perspectives. tgct arise by transformation of germ cells. the transformed germ cells exhibit ploripotentially to differentiate into embryonic. extra-embryonic, and somatic tissue types, and are highly sensi...
متن کاملEarly orchiopexy: prepubertal intratubular germ cell neoplasia and fertility outcome.
OBJECTIVES To investigate the prepubertal prevalence of intratubular germ cell neoplasia of the unclassified type (ITGCNU) and its significance as a predictor of testicular cancer and to evaluate the effect of early orchiopexy (at younger than 2 years of age) on subsequent fertility of patients with bilateral cryptorchidism. METHODS Testicular biopsies (n = 660) from 440 prepubertal patients ...
