- Abstract: This study was aimed to analyze the clinical and pathological characteristics of patients with primary extranodal lymphoma (PENL). A total of 236 patients with PENL were enrolled to evaluate the clinical and pathological features. The clinical data of 236 patients with PENL confirmed by pathological and immunohistochemical methods between January 2001 and March 2012 were analyzed retrospectively. The results indicated that: (1)236 patients with PENL accounted for 40.7% of lymphoma over the same period. Median age was 55 years old (from 16 to 91 years old) . There were 153 males and 83 females(ratio 1.8: 1). (2)The common sites of involvement were gastrointestinal tract, nasal cavity, tonsil, mediastinum, skin, spleen, testis, bone and soft tissue, central nervous system, which accounted for 30.1% (71/236), 10.6% (25/236), 8.9% (21/236), 5.9% (14/236), 5.1% (12/236), 4.7% (11/236), 4.2% (10/236) , 4.2% (10/236) , 3.0% (7/236) respectively. (3)Symptoms of PENL did not have special characteristics, however its signs usually manifested with the enlargement or mass of organs, which accounted for 66.9% (158/236) in this study. (4)According to WHO classification of tumours of haematopoietic and lymphoid tissues in 2008, the common pathological type of gastrointestinal lymphoma was diffuse large B-cell lymphoma, mucosa-associated lymphoid tissue lymphoma; the common pathological type of nasal lymphoma was extranodal NK/T cell lymphoma; the common pathological type of tonsillar lymphoma, testicular lymphoma, CNS lymphoma was diffuse large B-cell lymphoma. It is concluded that the primary extranodal lymphoma is not rare, it is alert to PENL while organs enlarge or mass forms, so that clinical physician should pay attention to tissue biopsy.
