Fibrinoid necrosis and hyalinization
observed in normal, diabetic and hypertensive placentae.
According to World Health Organization's (WHO) classification of Endocrine Organ Tumors, HTT is described as "an uncommon tumor of follicular origin characterized by trabecular pattern of growth and marked intra-trabecular hyalinization

A study involving 16 male golden retriever dogs deficient in dystrophin aged five to 51 months showed, in the histopathological analysis, the presence of hyalinization
and necrosis of muscle fibers as well as an increase of inflammatory cells, particularly mononuclear cells.
Plaques were mainly fibrotic with partial hyalinization
and myxoid changes.

of the lamina propria and atrophic crypts.
Hematoxylin-eosin staining highlighted the bone formation and hyalinization
without osteoblasts (Figures 4(a), 4(b), and 4(c)).
Histologically, we saw the proliferation of short spindle and polygonal cells on a background of abundant vessels showing vascular mural hyalinization
CsA causes nephrotoxicity which is characterised by arteriolar hyalinization
, shrunken glomeruli and stripped tubular necrosis.
The results revealed that in the irradiated group (Group II), the myocardial muscles were necrotic with leucocytes infiltration, fibrinoid necrosis in coronary vessel, edema and hyalinization
of myocardial muscles were remarked which is in agreement with the previous results observed by Baker et al.
