On day 90 the inflammation was subsided and degraded graft was surrounded by thick fibrocellular
13) Other findings include increased (>5 per high-power field) mitotic activity, comedonecrosis, micropapillary and squamoid growth patterns, and fibrocellular
In the case of crescentic glomerulonephritis, the number of glomeruli with crescents, and of those, the number that are, for example, cellular, fibrocellular
, and fibrous should be documented.
Histopathologially, intense fibrocellular reaction and infiltration of neutrophils was seen at host graft interface at day 7.
On day 7, intense fibrocellular reaction along with infiltration of inflammatory cells particularly neutrophils were observed at the host graft interface.
36) However, in daily practice they are usually segmental endocapillary proliferative lesions with or without accompanying capillary wall (fibrinoid) necrosis, crescents (cellular, fibrocellular, and fibrous types), or segmental sclerosis (Figure 3, A and B).
Chronic glomerular lesions include segmental and global glomerulosclerosis and fibrocellular (Figure 4, F) and fibrous crescents (Table 5).

Direct transfer of transforming growth factor beta 1 gene into arteries stimulates fibrocellular
The involved and noninvolved arteries also demonstrated intimal fibrocellular proliferation, causing marked luminal stenosis and occlusion (Figure 2).
PTTM is characterized by widespread fibrocellular intimal proliferation of the small pulmonary arteries and arterioles in patients with metastatic carcinoma; tumor cell emboli in PTTM may not only occlude the vessels but also activate both local and systemic coagulation systems, leading to thrombosis, fibrocellular and fibromuscular intimal proliferation, luminal stenosis, and finally occlusion.
