Malignant lymphoma of the testis

Primary testicular lymphoma with subcutaneous masses as the sole manifestation of the first relapse and central nervous system lymphoma as the second relapse: A case report and literature review

Primary testicular lymphoma (PTL) accounts for ~1% of all non-Hodgkin’s lymphomas and has a marked tendency for systemic relapse. The current study presents a unique case of testicular diffuse large B-cell lymphoma of non-germinal center B-cell subtype, with subcutaneous masses as the sole manifestation of the first relapse and central nervous system lymphoma as the second relapse. Subcutaneous relapse and subsequent brain relapse are extremely rare signs of PTL dissemination. The patient received methotrexate-based combined chemotherapy and achieved a partial response. This case presents a rare pattern of treatment failure in this malignant clinical entity.

Primary testicular non-Hodgkin's lymphoma associated with hemophagocytic syndrome: Case report and review of the literature

Primary testicular non-Hodgkin's lymphoma (TNHL) was first described as a clinical entity in 1866. It is a rare disease which accounts for 1% of all non-Hodgkin's lymphoma, 2% of all extranodal lymphomas and 5% of all testicular neoplasms. Hemophagocytic syndrome (HPS) is a rare but distinct condition caused by inappropriate and dysregulated activation of the immune system. We report a 47-year-old man with primary TNHL who developed HPS four months after occurrence of scrotal swelling. To the best of our knowledge, primary TNHL associated with HPS has not previously been reported.

There is a mass in the scrotum-what does it mean?: Evaluation of the scrotal mass

Similar to the experience of finding a lump upon physical examination of the breast, the detection of an intrascrotal mass is often a frightening experience for both the patient and his physician. Ultrasound is a nearly ideal modality for evaluation of the scrotum. This manuscript will review the sonographic assessment of the common pathologic and normal conditions that may present as a mass within the scrotum, including discussion of intratesticular and extratesticular etiologies.

Lymphoma of the testis and epididymis mimics chronic inflammation upon sonography

We report the sonographic findings in a case of lymphoma, which mimicked chronic inflammation. Scrotal gray-scale sonography revealed an irregularly margined, hypoechoic mass in the right testis and epididymis. Color Doppler sonography showed increased blood flow within the hypoechoic lesions in both testis and epididymis. Pathologic examination revealed a diffuse involvement of the testis and epididymis.

Primary testicular non-Hodgkin's lymphoma--a review article

Primary testicular non-Hodgkin's lymphoma was first described as a clinical entity in 1866. It is a rare disease and accounts for 1% of all non-Hodgkin's lymphoma, 2% of all extranodal lymphomas and 5% of all testicular neoplasms. It is the most common testicular tumor in males between sixty and eighty years of age. Testicular non-Hodgkin's lymphoma is unique in its high incidence of bilateral involvement (8-38%), and it is also the most common bilateral testicular tumor. Testicular non-Hodgkin's lymphoma has a predilection for spreading to non-contiguous extranodal sites, especially the central nervous system. Advanced-stage disease is usually managed with doxorubicin-based chemotherapy. For early-stage disease, opinion is divided regarding systemic chemotherapy following orchidectomy. The high incidence of spreading, especially to the central nervous system, leads to advocacy of the use of central nervous system prophylaxis with intrathecal chemotherapy. Prospective multicenter trials incorporating a large number of patients may lead to better guidelines for optimal management of this subtype of non-Hodgkin's lymphoma.

Diagnosis of a primary testicular lymphoma by echography and magnetic resonance imaging

We here describe a primary large B cell non-Hodgkin lymphoma of the right testicle in a 73-year-old male diagnosed with echography and magnetic resonance imaging. Treatment was based upon orchiectomy and chemotherapy, without any recurrence 2 years later. Ultrasonography and magnetic resonance findings with normal serum tumoural markers (AFP and B-HCG) can differentiate these tumors from germinal testicular tumors.
