Spermatocele is a benign pathology typically arising from the epididymis.
General
- Benign.
- Cyst of the epididymis (classic).
- May arise in the rete testis or vas deferens.[1]
Clinical:
- Often asymptomatic.
- Excised due to pain or mass effect.[2]
Microscopic
Features:
- Cyst lined by a simple ciliated epithelium.
- Contain sperm.
- Head: ~1/2 the size of a RBC, black.
- Tail: infrequently seen.
Note:
- Small cellular clusters may be present.
- May mimic small cell carcinoma.[3]
DDx:
- Hydrocele testis - do not contain sperm.
