Weak to moderate cytoplasmic staining with additional nuclear and occasional membranous positivity was seen in most normal tissues. Adrenal gland was strongly stained. Lung, appendix and prostate gland were virtually negative.
Most of the normal tissues displayed moderate nuclear positivity. Strong staining was observed in thyroid, neuronal cells and decidual cells. Additional luminal membranous staining was expressed in intestinal tract, gall bladder, renal tubules and pancreatic ducts.
