ObjectiveTo report a rare case of ALCL (Anaplastic Large Cell Lymphoma) with abundant neutrophils and necrosis and to analyse the histomorphologic subtypes and immunohistologic characteristics of ALCL.MethodsA biopsy of a painless tumor on a 26-year old male′s neck was taken for morphologic and immunohistochemical analyse.ResultsJudging from the morphologic feature of ALCL,the prognosis of the patient is good.ConclusionIt is necessary to do immunohistochemical staining in diagnosing an ALCL since p80NPM/ALK or ALK is the best antibody to distinguish ALCL from other lymphomas.``
