Respiratory adenomatoid hamartoma must be suspected on CT-scan enlargement of the olfactory clefts.

Objective: To demonstrate that Respiratory Epithelial Adenomatoid Hamartoma (REAH) of the nose, a recently individualized benign tumour, is characterized by a significant widening of the CT-scan width of the olfactory clefts.

Patients And Methods: Retrospective study comparing, in the axial and coronal planes, the CT-scan maximum width of the olfactory clefts, i.e.

Clinical factors influencing the eosinophil infiltration of nasal polyps.

Aims And Methods: Our study, based on a retrospective chart analysis, was aimed 1) to describe the varying degree of eosinophil infiltration in a series of 263 adult patients operated on diffuse and bilateral nasal polyposis (NPS) after failure of medical treatment, in 15 cystic fibrosis patients with bilateral nasal polyps, and in 31 patients with chronic sinusitis without polyps (18 bilateral, 13 unilateral) 2) to search for clinical factors that might influence the degree of eosinophil infiltration. Eosinophil infiltration was expressed semi-quantativity as a percentage of inflammatory cells.

Results: Our study confirms that eosinophil infiltration is a striking feature of nasal polyposis.
