Leydig cell tumor
Tumor - Leydig cell; Testicular tumor - Leydig; Testicular neoplasm
A Leydig cell tumor is a tumor of the testicle. It develops from Leydig cells. These are the cells in the testicles that release the male hormone, testosterone .
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
Testosterone
A testosterone test measures the amount of the male hormone, testosterone, in the blood. Both men and women produce this hormone. The test described...
Causes
The cause of this tumor is unknown. There are no known risk factors for this tumor. Unlike germ cell tumors of the testicles, this tumor does not seem to be linked to undescended testes .
Undescended testes
Undescended testicle occurs when one or both testicles fail to move into the scrotum before birth.
Leydig cell tumors make up a very small number of all testicular tumors. They are most often found in men between 30 and 60 years of age. This tumor is not common in children before puberty, but it may cause early puberty .
Early puberty
Puberty is the time during which a person's sexual and physical characteristics mature. Precocious puberty is when these body changes happen earlier...
Symptoms
There may be no symptoms.
When symptoms do occur, they can include:
- Discomfort or pain in the testicle
- Enlargement of a testicle or change in the way it feels
-
Excess growth of breast tissue (
gynecomastia
) -- however, this can occur normally in adolescent boys who do not have testicular cancer
Gynecomastia
When abnormally large breasts develop in males, it is called gynecomastia. It is due to the excess growth of breast tissue, not excess fat tissue....
- Heaviness in the scrotum
- Lump or swelling in either testicle
- Pain in the lower abdomen or back
- Not able to father children (infertility)
Symptoms in other parts of the body, such as the lungs, abdomen, pelvis, back, or brain may also occur if the cancer has spread.
Exams and Tests
A physical examination typically reveals a firm lump in one of the testicles. When the health care provider holds a flashlight up to the scrotum, the light does not pass through the lump. This test is called transillumination .
Transillumination
Transillumination is the shining of a light through a body area or organ to check for abnormalities.
Other tests include:
-
Blood tests for tumor markers:
alpha fetoprotein
(AFP), human chorionic gonadotropin (beta HCG), and
lactate dehydrogenase
(LDH)
Alpha fetoprotein
Alpha fetoprotein (AFP) is a protein produced by the liver and yolk sac of a developing baby during pregnancy. AFP levels go down soon after birth. ...
Lactate dehydrogenase
The lactate dehydrogenase (LDH) isoenzyme test checks how much of the different types of LDH are in the blood.
-
CT scan of the chest, abdomen
and pelvis to check if the cancer has spread
CT scan of the chest, abdomen
An abdominal CT scan is an imaging method. This test uses x-rays to create cross-sectional pictures of the belly area. CT stands for computed tomog...
-
Ultrasound
of the scrotum
Ultrasound
Ultrasound uses high-frequency sound waves to make images of organs and structures inside the body.
An examination of the tissue is usually done after the entire testicle is surgically removed (orchiectomy).
Treatment
Treatment of a Leydig cell tumor depends on its stage.
- Stage I cancer has not spread beyond the testicle.
- Stage II cancer has spread to lymph nodes in the abdomen.
- Stage III cancer has spread beyond the lymph nodes (possibly as far as the liver, lungs, or brain).
Surgery is done to remove the testicle (orchiectomy). Nearby lymph nodes may also be removed (lymphadenectomy).
Chemotherapy may be used to treat this tumor. As Leydig cell tumors are rare, these treatments have not been studied as much as treatments for other, more common testicular cancers.
Chemotherapy
The term chemotherapy is used to describe cancer-killing drugs. Chemotherapy may be used to:Cure the cancerShrink the cancerPrevent the cancer from ...
Support Groups
Joining a support group where members share common experiences and problems can often help ease the stress of illness.

Outlook (Prognosis)
Testicular cancer is one of the most treatable and curable cancers. Outlook is worse if the tumor is not found early.
Possible Complications
The cancer may spread to other parts of the body. The most common sites include the:
- Abdomen
- Lungs
- Retroperitoneal area (the area near the kidneys behind the other organs in the belly area)
- Spine
Complications of surgery can include:
- Bleeding and infection
- Infertility (if both testicles are removed)
If you are of childbearing age, ask your provider about methods to save your sperm for use at a later date.
When to Contact a Medical Professional
Call your provider if you have symptoms of testicular cancer.
Prevention
Performing testicular self-examination (TSE) each month may help detect testicular cancer at an early stage, before it spreads. Finding testicular cancer early is important for successful treatment and survival.
Testicular self-examination (TSE)
Testicular self-exam is an examination of the testicles that you do on yourself.
