Tissue Eosinophilia

Tissue eosinophilia in chronic sinusitis: quantification techniques.

OBJECTIVE To ascertain the reliability of a proposed method for quantifying tissue eosinophilia in sinus mucosa. DESIGN Prospective cohort study. INTERVENTIONS AND OUTCOME MEASURES Pathology slides from patients undergoing endoscopic sinus surgery for chronic rhinosinusitis were independently assessed by 2 reviewers. Using a proposed systematic counting method, the degree of tissue eosinoph...

Tissue eosinophilia and eosinophil degranulation in Riedel's invasive fibrous thyroiditis.

The etiology of Riedel's invasive fibrous thyroiditis (IFT) has remained obscure. This rare disorder has been confused in the past with the more common fibrous variant of Hashimoto's disease. The typical histological features of IFT, in particular the presence of an invasive fibrosclerotic process in conjunction with a prominent chronic inflammatory infiltrate, suggest that the release of fibro...

An unusual soft tissue tumour and peripheral eosinophilia.

Diagnostic importance of serological methods and eosinophilia in tissue parasites.

This case-control study was carried out to investigate whether eosinophilia is a common finding in parasitic diseases and to determine the prevalence of the parasitic diseases in definitive groups. Toxocariasis and fasciolosis were investigated in patients with eosinophilia, patients with non-eosinophilia, and healthy controls. All cases were analyzed for antibodies against Toxocara canis and F...

Tissue eosinophilia in head and neck squamous neoplasia: an update.

Eosinophils are multifunctional granulocytes that play an imperative role in health and disease. They have also been found to be a crucial component of peri- and intratumoral inflammatory infiltrate. Tumor-associated tissue eosinophilia (TATE) has been observed and described in many tumors, including head and neck neoplasia. The process of eosinophil recruitment and its function in tumors has n...
