Summary
A rare pure mature teratoma of the testis, presenting as scrotal swelling, was successfully treated with high inguinal orchiectomy. This benign-appearing tumor requires management similar to other nonseminomatous germ cell tumors due to recurrence potential.
Area of Science:
- Urology
- Oncology
- Pathology
Background:
- Testicular teratomas are germ cell tumors with diverse histological components.
- Distinguishing teratomas from inflammatory conditions like epididymitis can be clinically challenging.
Observation:
- A 46-year-old male presented with fever and painful right scrotal swelling, initially suspected as epididymitis.
- Surgical exploration revealed a testicular teratoma with epididymitis.
Findings:
- Histological examination confirmed a pure mature teratoma composed of epidermis, cartilage, hair, bone, and adipose tissue.
- Significant leukocyte infiltration in the epididymis indicated concurrent epididymitis.
- No recurrence was observed 6 months post-orchiectomy.
Implications:
- Pure mature testicular teratomas, despite benign histology, possess metastatic and recurrent potential.
- Management should align with nonseminomatous germ cell tumors, involving radical orchiectomy.
- Early diagnosis and appropriate treatment are crucial for managing testicular teratomas.
