Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in the Western World. It belongs to the low-grade non-Hodgkin lymphomas and is characterized by clonal reproduction of mature small-cell non-functional B-lymphocytes. CLL affects men somewhat more often than women and the average age at onset is over 50 years. In addition to regional lymph node swelling, typical symptoms include hepatosplenomegaly, leukocytosis and skin disorders such as eczema and pruritus. Manifestations in the oropharynx or hypopharynx are rare but should be kept in mind in the differential diagnosis.
