Abstract
We report a composite nodular ganglioneuroblastoma, distinctive for th e presence of coarsely granular black intracellular pigment, which was histochemically indistinguishable from melanin. Ultrastructurally, th e pigment was resolved as numerous heterogeneous lysosomes, containing material compatible with oxidized lipid residues, the accumulation of which may reflect acquired lysosomal dysfunction in individual tumour cells-a tumour cell 'storage disease'.
