Histologically, the deposits are composed of homogeneous eosinophilic material and surround seromucous
glands and cartilage plates (Figure 10, A).
In the duodenum, there are seromucous
glands known as Brunner glands in this layer.
It has been hypothesised that it arises from the schneiderian epithelium like the normal seromucous
glands of the nasopharynx and paranasal sinuses.
complex ultrastructural patterns of granules in the mucous and seromucous
and special seros cells in salivary glands.
In colloid inside of the polyp, we may observe very few small vessels, seromucous
glands and cellular infiltrations.
These glands extend laterally and towards the rear of the medial line, forming a horseshoe-like mass with an aperture toward the posterior draining through four to six ducts opening near the lingual frenulum; the characteristics of their secretion products have not been precisely determined, but have been histologically described as a set of seromucous
acini in their anterior part associated to mucous acini in their posterior part (3).
The classical sublingual gland is a mixed gland, with mucous acini outnumbering the seromucous
Frequently, hyaline cartilage, smooth muscle cells, elastic fibers, fibrous tissue, neural cells and seromucous
glands can be seen.
Seven [micro]m-thick histological sections stained with hematoxylin-eosin (HE) and Calleja showed the presence of elastic collagen fibers and seromucous
glands in the vestibular fold.
Polymorphous low-grade adenocarcinoma of seromucous
glands of the nasopharynx.
Twenty samples of serous, mucous, and seromucous
secretions were collected during surgery from the middle ears of patients suffering from otitis media.
