Abundant blood vessels,
hyalinization of the vascular wall, and interstitial fibrosis were observed.
[1516] It has been assumed that the application of force during orthodontic treatment leads to
hyalinization caused partly by anatomic and partly by mechanical factors.
vermicularis infection were re-examined for the presence of acute inflammation, congestion, hemorrhage, perforation, lymphoid hyperplasia (LH; lymphoid follicles forming germinal centers), necrosis, granuloma, obliteration,
hyalinization, tip involution/obliteration and mucosal architectural distortion.
We performed skin biopsy in a subset of patients and observed features like epidermal atrophy, flattening of rete ridges, thickening and
hyalinization of collagen bundles, encroachment of fat by collagen bundles and perivascular inflammatory infiltrate (Figure 5).
reported that atherosis is a pathology characterized by several microscopic changes that may or may not be associated: partial vascular obliteration, thickening of the vascular wall, leukocyte infiltration in the vascular wall, granulomatous reaction, presence of vascular
hyalinization, substitution of the intima by macrophages, and reduction in vessel lumens.
It is suggested that hypertension causes vascular endothelial changes including
hyalinization, which can lead to demyelination of the sensory tracts which are involved in carrying the visual sensation to the higher centers which might result in conduction abnormalities.[2] Hypertension leads to ischemia which can cause demyelination of the optic nerve or damage of the retinal ganglion cell before the development of hypertensive retinopathy.
Glomangiopericytomas also share the hemangiopericytoma-like vascular pattern and frequently exhibit perivascular
hyalinization (Figure 3, C).
On macroscopic examination, the presence of dilatation and perforation, maximum diameter of the specimen, surgical border, and presence of mucin and on microscopic examination, the level of architectural and cytologic atypia, intactness of the muscularis mucosa, submucosal fibrosis,
hyalinization, presence of atrophy in the lymphoid tissue, presence of invasion pushing toward the appendiceal wall, desmoplasia, and presence of single cell invasion were examined by the same pathological experts, who then reached a consensus (Tables 3A, 3B).
The histopathology of livedoid vasculopathy is characterized by intraluminal thrombosis, proliferation of the endothelium, and segmental
hyalinization of dermal vessels.
It is a thyroid tumor of a follicular origin and is characterized by trabecular pattern and intratrabecular
hyalinization (2).
Final pathology report revealed that alveolar collapse, thickening of alveolar septum, and peribronchial
hyalinization were observed.
Features that are often associated with more aggressive tumors include frequent mitosis, focal necrosis, neural invasion, pleomorphism, infiltration, and stromal
hyalinization. (12) Most of the reported central ACCs were low-grade and showed favorable prognosis.
