Charcot–Leyden crystals are composed of an eosinophilic lysophospholipase binding protein called Galectin -10. They vary in size and may be as large as 50 µm in length.[1] Charcot–Leyden crystals are slender and pointed at both ends, consisting of a pair of hexagonal pyramids joined at their bases.[1] Normally colorless, they are stained purplish-red by trichrome.
Clinical significanceedit
They are indicative of a disease involving eosinophilic inflammation or proliferation, such as is found in allergic reactions (asthma, bronchitis, allergic rhinitis and rhinosinusitis) and parasitic infections such as Entamoeba histolytica, Necator americanus, and Ancylostoma duodenale.
Charcot–Leyden crystals are often seen pathologically in patients with bronchial asthma.[2]

Los cristales de Charcot-Leyden son estructuras derivadas de los eosinófilos y de los basófilos, de moríología característica: en los frotes o en los cortes histológicos aparecen como cristales hexagonales, bipiramidales, de diversostamaños, intensamente eosinófilos con la coloración de hematoxilina-eosina, fácilmente identificables con el objetivo 1OX

They demonstrate that the crystals, but not the soluble proteins, are powerful promoters of allergic inflammation and can be targeted with crystal-dissolving antibodies to reverse disease symptoms.
