Lymphocytic orchitis: a case report.

Area of Science:

• Urology
• Pathology
• Immunology

Background:

• Testicular masses require thorough histopathologic evaluation to determine etiology.
• Lymphocytic orchitis is a recognized condition, often associated with specific causes.
• Distinguishing between different forms of orchitis is crucial for diagnosis and management.

Observation:

• A young male presented with a unilateral testicular mass of recent onset.
• Histopathologic examination of the orchiectomy specimen was performed.
• The examination revealed a nongranulomatous, lymphocytic infiltration of the testis.

Findings:

• No infectious agents were identified as the cause of the orchitis.
• No evidence suggestive of autoimmune disease was found.
• Lymphoma was excluded as a potential diagnosis.
• The findings are consistent with a nonspecific or idiopathic lymphocytic orchitis.

Implications:

• This case highlights a distinct clinicopathologic entity of lymphocytic orchitis.
• It expands the differential diagnosis for testicular masses in young men.
• Further research may be needed to elucidate the specific mechanisms behind idiopathic lymphocytic orchitis.
