Case 1
A 77-year-old man was admitted to the hospital with cutaneous erythematous tumors on the left leg (Fig 1, A). No clinical or radiologic signs of extracutaneous involvement were detected at that time. Histologic examination of the skin biopsy specimen showed dense lymphocytic infiltrate of centroblasts (large cells with round or oval nuclei and several small nucleoli) and immunoblasts. An immunohistochemical analysis identified the tumor as a CD20+, and a combined expression of MUM-1, Bcl-2 and
Discussion
Primary testicular lymphoma is a rare neoplasm accounting for approximately 9% of testicular malignant tumors.7 It is usually observed in elderly patients as a unilateral painless scrotal swelling, sometimes with a significant increase in the size of one or both testes or hydrocele.8 Histopathologically, a diffuse large B-cell lymphoma is the most common subtype of primary testicular lymphoma, although more aggressive subtypes, such as Burkitt lymphoma, are more prevalent in cases of secondary

2019, Hematology/Oncology Clinics of North AmericaCitation Excerpt :Staging includes CBC with differential, comprehensive metabolic panel, CT of the chest/abdomen/pelvis, bone marrow biopsy, PET-CT, and peripheral blood flow cytometry.38 Testicular ultrasound is recommended for male patients with new cutaneous DLBCL given secondary cutaneous testicular DLBCL demonstrates similar presentation and pathology.53 Standard treatment of pcDLBCL is based on intravenous rituximab and combination chemotherapy.

2014, BloodCitation Excerpt :Recommended staging is the same as that for other forms of aggressive NHL (positron emission tomography-computed tomography, bone marrow biopsy) with the addition of specific CNS staging with lumbar puncture for cerebrospinal fluid analysis by cytology and flow cytometry (since there is evidence to support improved sensitivity29) and brain magnetic resonance imaging. We recommend thorough examination of the skin because cutaneous DLBCL (leg type) and testicular DLBCL have been concurrently reported,30 and the skin is a potential site of extranodal recurrence. HIV serology should be performed.
