Definition / general
  • Rare non-Langerhans cell histiocytosis of bone of unknown etiology, with 50% also involving hypothalamic pituitary axis, lung, heart, retroperitoneum, skin, liver, kidneys, spleen, orbit
  • Nodal involvement is very rare, despite multisystem disease
Clinical features
  • Most common symptom is bone pain, usually involving lower extremities
  • Broad extraskeletal manifestations, including fever, weight loss, weakness, exophthalmos, diabetes insipidus, dysuria, abdominal pain, obstructive renal impairment, ataxia and paresis
  • Interstitial lung disease in 35% of patients with histiocytic cells and fibrosis seen in a predominantly perilymphangitic and subpleural pattern
  • Prognosis depends on extent and distribution of extraskleletal manifestations
  • Most common causes of death are respiratory distress, extensive pulmonary fibrosis and cardiac failure
Radiology description
  • Pathognomonic radiography showing bilateral, symmetrical osteosclerosis of metaphyseal and diaphyseal regions and sparing of the epiphyses
