In some selected patients lung transplantation may be an option, provided smoking has ceased. As LCH can affect most organ system, radiographic appearances are discussed separately see above. More recent evidence suggest that PLCH represents a myeloid neoplasm with inflammatory properties 9. Chemotherapeutic agents such as alkylating agentsantimetabolitesvinca alkaloids either singly or in combination can lead to complete remission in diffuse disease.


Specialty Histtiocitosis Langerhans cell histiocytosis LCH is a rare disease involving clonal proliferation of Langerhans cellsabnormal histiociyosis deriving from bone marrow and capable of migrating from skin to lymph nodes. Presence of Birbeck granules on electron microscopy and immuno-cytochemical features e.


These diseases are related to other histiiocitosis of abnormal proliferation histiocitosis x white blood cellssuch as leukemias and lymphomas.

Open biopsy for chronic diffuse infiltration lung disease: Eur Respir J, 9pp. Radiology abstract – Pubmed citation.

Arguments supporting the reactive nature of LCH include the occurrence of spontaneous remissions, the extensive secretion of multiple cytokines by dendritic cells and bystander-cells a phenomenon known as cytokine histlocitosis in the lesional tissue, favorable prognosis and relatively good survival rate in patients without organ dysfunction or risk organ involvement.
