A 68-yeаr оld mаn hаs nоted the presence оf several lumps on the right side of his neck for the past 5 months. On physical examination he has firm, non-tender, movable lymph nodes palpable in right posterior cervical region. He does not have splenomegaly or hepatomegaly. Laboratory studies show normal hemoglobin and red blood cell levels, but elevated white blood cell numbers. A cervical lymph node biopsy is performed and on microscopic examination shows numerous non-functional B lymphocytes expressing CD5. These cells are negative for CD23. Molecular studies indicate evidence of a chromosomal translocation resulting in overexpression of cyclin D. His disease is resistant to chemotherapy and the patient dies from his condition. Which of the following is the most likely diagnosis?
