Histology Findings
|
|---|---|---|---|---|---|
|
Germ cell tumour
|
Seminoma
|
Most common subtype
Majority of post-pubertal tumour
|
Best prognosis due to slow growth and late metastasis.
Some may secrete β-hCG, leading to gynaecomastia.
|
|
“Fried-egg” appearance and lymphocytic stroma.
|
|
Yolk sac tumour
|
Majority of pre-pubertal tumour
|
|
Gross yellow mucinous cut surface (resemble primitive glomeruli)
|
||
|
Choriocarcinoma
|
Rare but considered the most aggressive subtype
|
Almost always secretes β-hCG, often leading to gynaecomastia
|
|
Contains syncytiotrophoblasts and cytotrophoblasts
|
|
|
Teratoma
|
Common in children (typically benign)
Rare in adults (can be malignant)
|
|
Contains various tissue types such as teeth, cartilage, bone, and hair
|

|
Non-germ cell tumour
|
Leydig cell tumour
|
Non-germ cell tumours make up ~5% of all testicular tumours (rare)
|
Secretes testosterone, which can cause precocious puberty in boys
|
|
|
|
Sertoli cell tumour
|
Secretes oestrogen, which can lead to gynaecomastia
