A Case of Bronchial Obstruction Caused by Charcot-Leyden Crystals / 소아알레르기및호흡기학회지

ABSTRACT

Charcot-Leyden crystals are slender, hexagonal, bipyramidal crystals formed predominantly from eosinophil but also from basophil granules composed of a single protein of 17,400 daltons of lysophospholipase activity. It has been identified in a variety of body fluids and tissues in human tissues and secretions in association with eosinophilic inflammatory reactions, asthma, myeloid leukemias, and allergic, parasitic, and other diseases. In this report, we describe a child with bronchial obstruction and subsequent atelectasis caused by Charcot-Leyden crystals containing fibronous material who was treated with flexible bronchofiberscope to remove it.
