Results showed severe inflammatory reaction of the excised tracheal rings, with heterophils, lymphocytes, histiocytes, multinucleated giant cells, and fibrin, chronic active fibroplasia
, complete loss of the respiratory epithelium, and necrosis of the tracheal cartilage.
Frequent eye examinations of premature newborns play an important role in the early diagnosis and treatment of retrolental fibroplasia
18] Larval extracts and EGF have been shown to stimulate fibroplasia
through different mechanisms and to have a synergistic effect.
Spaces between glands are usually markedly widened, and the intervening stroma shows fibroplasia
with or without hyalinization (Figure 7, A and B).
Lung had suppurative pneumonia with the presence of embolic thrombi and intra-alveolar colonies of gram negative bacilli and coccobacilli (Figure 1D); severe interstitial fibroplasia
with mixed inflammatory infiltrate was observed.
1) During adolescence, the histological pattern is similar to that of an epidermal nevi, which includes acanthosis and fibroplasia
of the papillary dermis.
Chronic trauma, infection, hyperkeratosis, decreased vascular supply, and impaired sensation may produce excessive fibroplasia
in a susceptible host.
Keloids and hypertrophic scars are an exaggeration of fibroplasia
in dermal repair.
The pathologic diagnostic criteria for calciphylaxis utilized at the Mayo Clinic require skin biopsy evidence of medial calcification and intimai fibroplasia
of pannicular arterioles with cutaneous necrosis.
Histologically, severe inflammatory infiltrate, fibroplasia
and densely packed collagen fibres were observed.
These cases were classified according to the major histological appearance characterized by diffuse vacuolation in the cytoplasm of hepatocytes in acute cases, proliferation of the bile ducts and mild fibroplasia
in subacute cases and severe fibrosis in chronic cases Guerrre et al.
