To explore the distribution of lymphoid neoplasms in Northwest China, the clinical and pathological data of lymphoma patients from 2006 to 2014 were analyzed according to the WHO classification in Xijing Hospital. Of the 3244 cases, mature B-cell neoplasms occupied 60.7%, while mature T/NK-cell neoplasms and Hodgkin's lymphomas (HL) occupied 26.2% and 8.1%, respectively. The most common subtype of lymphoma was diffuse large B-cell lymphoma (35.0%), followed by extranodal NK/T-cell lymphoma, nasal type (ENKTCL) (12.9%) and marginal zone B-cell lymphoma (7.8%). Mixed cellularity (34.0%) was the most common subtype of HL. The especially high proportion of ENKTCL was the most outstanding feature of our study in comparison to previous reports. The mean age of all lymphoid neoplasms cases was 51years and most subtypes showed male predominance, with an average male-female ratio of 1.6. Extranodal lymphomas took up about 60% of all cases and gastrointestinal tract was the most frequently involved site. In conclusion, the distribution of lymphoid neoplasms of Northwest China showed some features similar to previous reports of China and other countries, but some subtypes presented distinct features.
