• mixed atrophy of the testis
  23 January 2012

  Mixed atrophy of the testis (MAT) is a frequent finding in biopsies of formerly cryptorchid and/or infertile patients.
  Mixed atrophy of the testis (MAT) is defined as the synchronous occurrence of both seminiferous tubules containing germ cells and Sertoli cell only-tubules in variable proportions.
  In tubules containing germ cells, different types of abnormalities in spermatogenesis may be seen.
  The presence of adult spermatids in the biopsy, even in small numbers, correlates with (...)

  Carcinoma in situ (CIS) of the testis
  Carcinoma in situ (CIS) is the precursor of malignant testicular germ cell tumors (GCTs) of adolescents and young adults, being the neoplastic counterpart of primordial germ cells/gonocytes.
  Carcinoma in situ cells will develop into invasive seminoma/nonseminoma.
  Gonadoblastoma (GB) is the precursor of invasive GCTs in dysgenetic gonads, predominantly dysgerminoma (DG).
  In this process, part of the Y chromosome (GBY region) is involved, for which (...)

• testicular adrenal rest tumor
  9 December 2011

  Testicular adrenal rest tumors are frequently associated with congenital adrenal hyperplasia (CAH). These ACTH-dependent tumours cannot be easily distinguished histologically from Leydig cell tumors (Leydig cell adenoma).
  Infertility observed in adult males with congenital adrenal hyperplasia (CAH) has been associated with testicular adrenal rest tumors (TART) that may originate during childhood. TART in prepubertal males with classic CAH could be found during childhood. (#17895312#) (...)
