What is the typical presentation of a Testicular Lymphoma?

The typical presentation of a Testicular Lymphoma is characterized as a palpable, slightly painful mass. This aligns with the common clinical presentation of testicular lymphomas, which are most often non-seminomatous germ cell tumors that can manifest as a mass in the testis.

In many cases, these masses may cause slight discomfort due to the involvement of surrounding tissues or because they are expanding within the scrotal sac. The pain is usually mild, distinguishing it from other conditions that may present more acutely or severely.

The other presentations mentioned do not align as closely with testicular lymphoma. A completely painless mass can occur but is not typical for lymphoma. Diffuse swelling without pain may suggest other diagnoses, like hydrocele or epididymitis, and the presence of firm nodules with discoloration is more characteristic of testicular torsion or trauma rather than lymphoma.
