BCR and amyloidoma: Subcutaneous ALκ(TAL) amyloidomas contained a plethora of neutrophil extracellular traps (NETs), indicating activation of the neutrophils in the amyloid; however, these were not observed in ALλ(CLA) lesions, suggesting that neutrophils become differentially activated when entering in ALκ(TAL) lesions compared to ALλ(CLA) lesions (Figures 3, 4).
