Definition / general
  • Normal counterpart is presumed to be mature Langerhans cell
  • Almost always due to systemic disease often involving spleen, liver, skin, bone and bone marrow; but may also present as a solitary lesion (e.g. eosinophilic granuloma) in bone or lung
  • Usually found only at autopsy in spleen, associated with fatal thrombocytopenia due to hypersplenism
  • Can occasionally be associated with T cell lymphoblastic leukemia
  • Langerhans cell sarcoma: cytologically malignant (Am J Dermatopathol 2006;28:36)
Gross description
