We report herein on a case of anaplastic large cell lymphoma with Charcot-Leyden crystals (CLCs). The patient was a male in his 30 s. Large lymphoma cells were found in an imprint specimen, and eosinophils and CLCs were observed in the background. The CLC formation involves ETosis (extracellular trap cell death) of eosinophils. The CLCs appeared with granular material associated with eosinophil disintegration. There have been no previous reports published on a lymphoma with CLCs, and the cause of the ETosis in the tumorous lesion is unknown. In the future, it will be necessary to examine various cases with CLCs with many different approaches.
