Typical carcinoid tumor arising in the nose and paranasal sinuses--case report.

Carcinoid tumors arise from neuroendocrine cells, many of which are present in the digestive tract and lungs. There have been few reports of carcinoid tumors occurring in the nose and paranasal sinus area, and they are very rare. We encountered a patient with a carcinoid tumor that arose in the nose and paranasal sinuses, and we report the case with a review of the literature.

Glucocorticoid receptor immunoreactivity of eosinophils in nasal polyps.

Conclusion: The higher level of glucocorticoid receptor (GR) expression in cases of chronic sinusitis with bronchial asthma or allergic rhinitis suggests that glucocorticoids may exert a greater influence on eosinophils, thereby making them more effective in the treatment of polyps or chronic sinusitis.

Objectives: The GR immunoreactivity of eosinophils in nasal polyps was investigated to elucidate the mechanism by which glucocorticoids interact with eosinophils.

Materials And Methods: Nasal polyp specimens were divided into 3 groups: 7 patients with chronic sinusitis alone (CS only group), 12 patients with chronic sinusitis complicated by perennial allergic rhinitis (CS/AR group), and 6 patients with chronic sinusitis complicated by bronchial asthma except for aspirin-induced asthma (CS/asthma group).
