The Birbeck granule was originally identified in Langerhans cells of the skin, then in adult pulmonary LCH, and later in cutaneous and bone lesions of childhood. The structure forms where the C-type lectin Langerin (CD207) accumulates and the Birbeck granule appears to be related to endosomal trafficking.
