Testicular epidermoid cysts (TECs) are rare benign tumors that can be mistaken for malignant growths. Accurate diagnosis is crucial to avoid unnecessary orchiectomy and ensure appropriate patient management.
Area of Science:
- Urology
- Pathology
- Oncology
Background:
- Testicular epidermoid cysts (TECs) are rare benign neoplasms.
- Distinguishing TECs from malignant testicular tumors can be challenging.
- TECs are sometimes classified as prepubertal teratomas.
Purpose of the Study:
- To report a case of testicular epidermoid cyst.
- To highlight the diagnostic challenges associated with TECs.
- To emphasize the importance of accurate diagnosis in testicular masses.
Main Methods:
- A case presentation of a 67-year-old man with a chronic painless testicular mass.
- Physical examination revealed an immobile intrascrotal mass without lymphadenopathy.
- Scrotal ultrasound showed an avascular intratesticular mass; histopathology confirmed an epidermoid cyst.
Main Results:
- Histopathological examination revealed a well-defined, encapsulated mass consistent with an epidermoid cyst.
- The cyst was lined by a fibrous membrane and contained a porridge-like substance.
- No evidence of germ cell neoplasm in the adjacent testicular parenchyma was found.
Conclusions:
- Testicular masses should be presumed malignant until definitively proven otherwise.
- Accurate preoperative diagnosis is essential to prevent unnecessary radical orchiectomy.
- Early and precise diagnosis of TECs can guide appropriate clinical management.
