Around the adenomere it is possible to distinguish stellate myoepithelial cells, as well as around the intercalated ducts
(Leal et al., 2003; Amano et al., 2012).
Oncocytomas originate mainly from the intercalated duct
cells consequently most of the oncocytomas occur in the parotid gland abundant in intercalated ducts
It arises specifically from the intercalated ducts
, and electron microscopy shows that it arises from cells that can differentiate into epithelial and myoepithelial cells.
Histologically, the tumour is biphasic with clear myoepithelial cells surrounding epithelial-lined ducts resembling intercalated ducts
Sometimes ducts open directly into cysts and some acinar units communicate with the cyst suggesting its origin from intercalated ducts
. There is flocculent, eosinophilic material and a few scattered macrophages found in most of the cystic lumina.
Myoepithelial cells are specialized basal epithelial cells that are found in the secretory endpieces and intercalated ducts
of the normal exocrine glands, such as the salivary glands, respiratory tract glands, lacrimal glands, mammary glands, prostate glands, and sweat glands.
(13) Recently, Ohtomo et al (14) found SOX10 was expressed in both luminal and abluminal cells of intercalated ducts
of normal human major salivary glands.
were present close to developing islet tissue in the twenty specimens of groups A and B and not present in group C.
Results: The mean number of intercalated ducts
in the right gland "a" and "b" parts, and in the left gland "a" and "b" parts was 1.45 +- 0.14, 1.39 +- .009, 1.31 +- 0.11 and 1.18 +- 0.10 respectively.
The luminal diameter of acini was larger and had more of secretory granules than the intercalated ducts
. The rough endoplasmic reticulum elongated into spiral form in the infranuclear cytoplasm of the epithelial cells.
In head and neck pathology, discovered on gastrointestinal stromal tumor protein 1 (DOG1) expression was seen in normal serous acini, mucous acini, and distal intercalated ducts
. All acinic cell carcinomas were positive for DOG1, with predominantly apical/luminal membranous staining.
Plenty of intercalated ducts
, striated and excretory ducts are seen scattered.
