Testicular epidermoid cyst

A testicular epidermoid cyst is a benign, non-cancerous growth that occurs within the testicles.

These cysts are characterized by a sac-like structure filled with keratin, a protein that is a key component of skin, hair, and nails.

Testicular epidermoid cysts are distinct from other cystic formations as they do not contain fluid but rather a thick, cheesy substance composed of keratin.

Clinically, these cysts usually present as a painless, palpable mass within the testicle.

They are most commonly identified in men between the ages of 20 and 40.

Although benign, differentiating epidermoid cysts from malignant testicular tumors is crucial, as the latter can have serious health implications.

Imaging studies, particularly ultrasound, are instrumental in evaluating these cysts.

On ultrasound, epidermoid cysts typically appear as well-defined lesions with characteristic concentric rings or 'onion skin' appearance due to layers of keratin.

While testicular epidermoid cysts do not pose a direct threat to health, they may require surgical excision if they cause discomfort or if there is uncertainty in diagnosis.

Regular follow-up and monitoring are advised to ensure that there is no change in size or character, indicating a need for intervention.

This condition is best managed by a specialist in urology or a healthcare professional with expertise in male reproductive health.
