title: Immunoglobulin synthesis in hairy cell leukaemia. Ultrastructural immunocytochemical study of 3 cases.
abstract: 3 cases of hairy cell leukaemia were studied with ultrastructural immunocytochemical methods using an anti human Ig HRPO-Fab fragment. Ig were detected on the cell surface, in the perinuclear cisterna and endoplasmic reticulum of hairy cells. Evidence of Ig in these sites demonstrates a B-lymphoid differentiation of the leukaemic cells.
