Relative incidences of testicular tumors, showing seminoma at bottom left. [2] A seminoma is a germ cell tumor of the testicle or, more rarely, the mediastinum or other extra-gonadal locations. It is a malignant neoplasm and is one of the most treatable and curable cancers, with a survival rate above 95% if discovered in early stages. [3 ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Spermatocytic tumor is a rare tumour, making up only one to two percent of all testicular germ cell tumours. Men presenting with this tumour are generally 50 to 60 years old, and its occurrence is rare in men under 30 years old. Most present with slow, painless testicular enlargement, which may involve both testes. [1]
The World Health Organization classification of testicular tumours [4] subdivides ITGCN into (1) a more common, unspecified type (ITGCNU), and (2) other specific subtypes. The most common specific subtypes are intratubular embryonal carcinoma and intratubular seminoma. [citation needed]
Germ cells tumors constitute a vast majority of the incidences of testicular tumors. [3]GCTs are classified by their histology, [4] regardless of location in the body. . However, as more information about the genetics of these tumors become available, they may be classified based on specific gene mutations that characterize specific tu
Globally testicular cancer resulted in 8,300 deaths in 2013 up from 7,000 deaths in 1990. [9] Testicular cancer has the highest prevalence in the U.S. and Europe, and is uncommon in Asia and Africa. [67] Worldwide incidence has doubled since the 1960s, [68] with the highest rates of prevalence in Scandinavia, Germany, and New Zealand. [citation ...
Varicoceles are more common on the left side due to the following reasons (a) The left testicular vein is longer; (b) the left testicular vein enters the left renal vein at a right angle; (c) the left testicular artery in some men arches over the left renal vein, thereby compressing it; and (d) the descending colon distended with feces may ...
[4] [9] Most ovarian teratomas are mature. [10] In adults, testicular teratomas are generally cancerous. [11] Definitive diagnosis is based on a tissue biopsy. [2] Treatment of coccyx, testicular, and ovarian teratomas is generally by surgery. [5] [6] [12] Testicular and immature ovarian teratomas are also frequently treated with chemotherapy ...
