There were 11 glomeruli with large fibrous crescent, three with large fibrocellular
crescent and six with global sclerosis.
The reasons for considering periodontal ligament origin is the exclusive occurrence of these fibromas in the gingiva (interdental papilla), the proximity of gingiva to the periodontal ligament and the presence of oxytalan fibers within the mineralized matrix of some lesions and the fibrocellular
response, which is similar to other reactive gingival lesions of periodontal ligament origin.
by structural and functional deterioration descending from variable and combined effect exercised by fibrosis, hypertrophy with fibrocellular
disarray, hibernating myocardium, apoptosis, all separately or simultaneously operating in elderly heart).
Thin paraffin sections (5 [micro]m) were cut and stained with Haematoxylin and Eosin (Luna, 1968) for routine fibrocellular
architecture, Van Gieson's stain (Luna) for collagen fibers, Gomori's reticulin method (Luna) for reticular fibers and Weigert's resorcin fuchsin and orcein (Luna) stain for elastic fibers.
Renal biopsy showed fibrocellular
crescents and little evidence of diabetic glomerulosclerosis (Fig.
Histopathologic examination of the surgical specimen showed that it was made up of immature trabeculae of osteoid in a fibrocellular
and myxoid stroma (figure 2).
3) An intravitreal injection resulting in complete posterior vitreous detachment is less traumatic than vitrectomy and might be beneficial as prophylactic treatment regime in retinal disease characterized by fibrocellular
and fibrovascular proliferation of vitreoretinal interface to prevent advanced stages of disease.
Renal biopsy, during which 24 glomeruli were examined including four cellular, six fibrocellular
, and one fibrous crescent, revealed necrotizing crescentic pauci-immune glomerulonephritis with fibrinoid necrosis in the capillary loops of some glomeruli.
Around sutured material there was fibrocellular
reaction with presence of lymphoid aggregates.
The vitreous contained erythrocytes and fibrocellular
tissue in the vitreous base (proliferative vitreoretinopathy).
