Clusterin is expressed in a Golgi-associated pattern in anaplastic large-cell lymphoma.125–127 In contrast, clusterin is present in only 3.5% of peripheral T-cell lymphoma unspecified cases from three series124,125,127 and only 13% of other T-cell neoplasms were positive and usually showed a more diffuse cytoplasmic staining rather than the more distinct Golgi pattern of reactivity seen in anaplastic large-cell lymphoma.125,127. The gene discussed is CLU; the disease is T-cell non-Hodgkin lymphoma.
