Introduction: There is not a neoplasm that has generated such confusion on its classification system such as the Non- Hodgkin's lymphoma. An adequate classification is necessary for diagnosis, prognostic and treatment. Objectives: To classify the NHL from the Bucaramanga metropolitan area poblational cancer registry. Patients and methods: An observational cross-sectional study was made, using as population the patients with NHL from the Bucaramanga metropolitan area from January 2000 until December 2006. The information was obtained from the clinical records and inmunohistochemistry in paraffin blocks. The WHO lymphoma classification was used. Results: 320 patients were studied and a predominance of the disease was found on the 6th and 7th decade of life. Gender distribution was higher in men with 61.26% and women 45.6%. The anatomical site more frequently affected were the cervical lymph nodes with 25.6%. Most of them expressed B antigens, 86.8%, and T, 1.8%. The most frequent subtype was diffuse large B cell in 29.6%. Conclusions: Most of the NHL from the Bucaramanga metropolitan area are nodal, of B lineage, and diffuse large cell subtype. The limited use of other techniques for the classification of these neoplasms in our region was evident. Salud UIS 2011; 43(1): 39-47.
