Calcifying fibrous pseudotumours (CFPTs) are paucicellular collagenous
lesions with scattered chronic inflammation and focal calcifications.3 Many previous case studies and literature reviews have suggested that CFPT is a cell-poor, end stage of inflammatory pseudotumor (IPT).4 Although lung involvement is reported to be the most common presentation of IPTs, variants are known to involve almost any type of anatomical location.
We think our non-invasive approach has the potential to open avenues to treat or repair collagenous
tissue without causing tissue damage."
The lesions showed a homogeneous eosinophilic collagenous
matrix background, in which some areas displayed hyalinization [Figure 2]b.
When correlated histologically, hyperintensity on T2W and absent enhancement correspond to hypocellular areas with abundant collagenous

Uncomfortable loads in flexion along with the previous translation and the time factor can be a cause of distortion or damage of any spinal collagenous
A complex pattern of anastomosing empty spaces in the dense collagenous
stroma is also seen.
In order to remove non collagenous
substance and to make the tissue very loose, the chicken feet waste was treated with 0.1 N of NaOH for 24 hours.
The lesion was well circumscribed and contained fibroblastic spindle cells in a collagenous
background, and some inflammatory cells were seen.
The histopathological examination revealed vascular formations between osseous and collagenous
structures, angiomatosis, and papillary endothelial hyperplasia conclusive of a capillary hemangioma (Figures 4(a) and 4(b)).
However, the collagenous
portion remained constant before (Figure 6(e)) and after decalcification (Figure 6(f)).
The Sirius Red/Fast Green Collagen Staining kit (Chondrex, Redmond, WA, USA, #9046) was used to assess the amount of collagenous
and noncollagenous protein formation by hGFs that were cultured on control and 3% and 5% Ti[O.sub.2] discs (n = 3).
