Cerebrum, grey matter
Cerebrum, white matter
Colon descendens, mucosa - Strong Cytokeratin 19 staining of all epithelial cells.
Colon descendens, muscular wall
Duodenum, Brunner gland - A variable, usually weak cytokeratin 19 staining is seen in a fraction of cells in Brunner glands.
Duodenum, mucosa - KRT 19 staining is stronger at the surface mucosa than in deeper located glandular cells.
Ectocervix - In non-keratinizing squamous epithelium, the basal cells are Cytokeratin 19 positive while the remaining layers are usually negative.
Endocervix - Strong Cytokeratin 19 staining of all epithelial cells.
Endometrium, secretion - Strong Cytokeratin 19 staining of all epithelial cells.
Epididymis - Strong Cytokeratin 19 staining of all epithelial cells.
Esophagus, squamous epithelium - Cytokeratin 19 staining is usually limited to the basal cells. In this sample some additional "higher" Cytokeratin 19 positive squamous cells are seen.

Fat
Gallbladder, epithelium - Strong Cytokeratin 19 staining of all epithelial cells.
Heart
Ileum, mucosa - Strong Cytokeratin 19 staining of all epithelial cells.
Kidney, cortex - In the kidney, a large fraction of the cells of the distal tubuli and collecting ducts as well as parietal epithelial cells of the Bowman capsule show strong Cytokeratin 19 immunostaining.
Kidney, medulla - A large fraction of the cells of collecting ducts show strong Cytokeratin 19 staining.
Liver - A strong Cytokeratin 19 staining is seen in bile ducts including small periportal ducts.
Lung- Pneumocytes show a moderate Cytokeratin 19 staining.
Lymph node
Ovary, stroma
Pancreas - Cytokeratin 19 positivity is seen in interlobular and intercalated ducts of the pancreas.
Parathyroid gland - All epithelial cells show at least a moderate Cytokeratin 19 staining.
Parotid gland - In salivary glands, cytokeratin 19 is seen in intercalated and striated ducts, myoepithelial cells (and to a lesser and variable extent) glandular cells of salivary glands.
Pituitary gland, anterior lobe
Pituitary gland, posterior lobe
Pregnant uterus (decidua)
Placenta, early
Placenta, mature - The syncytiotrophoblast, and to a somewhat lesser extent the cytotrophoblast of the placenta are Cytokeratin 19 positive.
Placenta (amnion and chorion) - Amnion and chorion cells of the placenta are cytokeratin positive.
Prostate - A variable cytokeratin 19 staining intensity of both apical and basal cells can occur in the prostate but not in all glands and not in all samples.
Rectum, mucosa - Strong Cytokeratin 19 staining of all epithelial cells.
Seminal vesicle - Strong Cytokeratin 19 staining of all epithelial cells.
Sinus paranasales - Strong Cytokeratin 19 staining of all epithelial cells.
Skin
Spleen
Stomach, antrum - Strong Cytokeratin 19 staining of all epithelial cells.
Stomach, corpus - Cytokeratin 19 staining is strong in most epithelial cells of the stomach corpus except staining being absent in parietal cells and only weak in chief cells.
Striated muscle
Testis
Tonsil - A strong Cytokeratin 19 positivity is seen in some but not all squamous cells of tonsil crypts.
Tonsil, surface epithelium - Cytokeratin 19 staining is largely limited to the basal cells of the squamous epithelium.

Urinary bladder - Urothelium always shows a strong Cytokeratin 19 positivity of all epithelial cells.
Uterus, myometrium - A weak to moderate cytokeratin 19 immunostaining can be seen in smooth muscle of the myometrium.
Uterus, myometrium - Cytokeratin 19 positivity is not always seen in myometrium.
