Objective:
To investigate the clinicopathologic characteristics and reason of tissue injury caused by klebsiella rhinoscleromatis(KR) infection.
Methods:
Twenty-four cases of rhinoscleromas in the nasal and pharyngeal region in this hospital from March 1983 to March 1998 were studied retrospectively. Warthin-Starry (W-S) stain was used in all cases and CD43, CD20, CD68, Lysozyme mark were observed in eleven specimens by ABC immunochemical method. Two cases were studied further with transmission electron microscopy.
Results:
A great number of KR were found in Mikulicz cells and were confirmed further in the phagosomes in cytoplasm of Mikulicz cells, where a small number of endoplasmic reticulums and lysozymes was squeezed to the side of cells. A few of T-lymphocytes was found within the granuloma.
Conclusion:
Cellular immunity function of the patient with rhinoscleroma was depressed and the response to immunization of host which regards to KR was the major cause of tissue injury.
