Nodal marginal zone lymphoma
NMZL constitutes less than 2% of lymphoid neoplasms and most often occurs in adults with a median age of approximately 60 years old with no sex predominance. Patients with chronic hepatitis C infection are at increased risk. Pediatric nodal marginal zone lymphoma is a distinct entity with marked male predominance and localized disease.
Patients present with local or generalized lymphadenopathy B symptoms (such as fever, weight loss, or night sweats), or they may present with no symptoms at all. Approximately one-third of patients have concomitant extranodal marginal zone lymphoma; therefore, adequate surveillance for extranodal involvement should be performed, especially in patients with history of autoimmune disorders.
