PY - 2015 T2 - Fishman's Pulmonary Diseases and Disorders, 5e AB - Pulmonary Langerhans’ cell histiocytosis is part of a large spectrum of disorders characterized by abnormal organ infiltration by Langerhans’ cells, which are highly differentiated cells in the monocyte-macrophage line that are also found in the dermis of the skin, reticuloendothelial system, pleura, and lung. Clinically, these disorders vary greatly, ranging from mild, single-organ disease to acute, disseminated life-threatening presentations. Depending on the sites involved and severity, the entity now referred to as Langerhans’ cell histiocytosis has been previously defined as eosinophilic granuloma, Hand–Schüller–Christian disease, and Letterer–Siwe disease. A more recent and simplified system of classification includes Langerhans’ cell histiocytosis with single-organ involvement or with multisystem involvement.1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/20 UR - accessmedicine.mhmedical.com/content.aspx?aid=1122361335 ER -
