Overview

Scrotal masses may be differentiated according to clinical features, laboratory findings, imaging features, histological features, and genetic studies from other diseases that cause testicular mass with discomfort, back pain, abdominal discomfort, or abdominal mass. Common differential diagnoses include yolk sac tumor, teratoma, choriocarcinoma, embryonal cell carcinoma, seminoma, and testicular lymphoma (usually non-Hodgkin lymphoma).

Differential Diagnosis

The table below summarizes the findings that differentiates scrotal mass according to the clinical features, laboratory findings, imaging features, histological features, and genetic studies.

Scrotal Swelling Diseases Clinical manifestations Para-clinical findings Gold standard Associated
Painful Symptoms Physical examination
