We report a 45-year-old man with complaints of chest pain and weight loss who was referred for a bone marrow/trephine procedure to the Aga Khan University Hospital. Bone marrow examination showed plasmacytosis of 95% with plasma cells containing coarse Auer rod-like azurophilic inclusions, which failed to stain positively with Sudan Black B or periodic acid Schiff stain. These inclusions have rarely been previously reported as they are more significant morphologically rather than having a prognostic value.
