Introduction: Richter syndrome refers to the transformation from chronic lymphocytic leukemia to assaultive lymphoma, often a diffuse large B-cell lymphoma, and has a greatly poor prognosis. Richter syndrome is characterized by rapidly growing lymphadenopathy but rarely presents with extra-nodal involvement, common sites being the digestive tract, lungs, kidneys, and central nervous system. However, Richter syndrome with testicular involvement is extremely rare.
Case presentation: Herein we report a very scare case of a male at the age of 72 with Richter syndrome and testicular involvement, diagnosed by the investigation of bilateral scrotal swellings. The patient had attained disease-free survival for over a year with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone, and the intrathecal administration of chemotherapeutic agents after diagnosis by immediate orchiectomy.
Conclusion: An early pathological diagnosis by immediate orchiectomy and the early initiation of induction immunochemotherapy may be good prognostic factors in Richter syndrome involving the testes.
