Patient is a 69-year-old male who presented to his physician complaining of abdominal pain. A routine CBC revealed a WBC of 250,000/ul with 95% of the cells being lymphocytes. An abdominal ultrasound showed splenomegaly to 14cm. His peripheral smear is shown. The cells are intermediate in size with agranular cytoplasm. The nuclei are round and several of the cells contain a single large nucleolus. Scattered "basket" or smudge cells are also noted. Platelets are present but decreased.
