scrotal lumps and swellings
Last reviewed 01/2018
A scrotal mass may have a wide range of clinical diagnosis which varies form benign congenital conditions to life-threatening malignancies to acute surgical emergencies (1).
Neoplasia, inflammation or anatomical defects may cause scrotal masses (2).
The cardinal sign of a true scrotal mass is this it is possible to get above it.
A cystic mass can usually be transilluminated. Solid masses do not transilluminate.
An acutely painful scrotum should be treated as a torsion of the testis until proven otherwise.
It is important to differentiate whether the scrotal mass is intratesticular or extratesticular and whether it is cystic or solid (2).
- intratesticular solid mass - should be regarded as malignant except on rare occasions
- if extratesticular and cystic - most likely to be benign
- extratesticular solid masses – almost always benign (with 3% being malignant) (3)
