Langerhans cell histiocytosis

Langerhans cell histiocytosis

Characteristics
  • It is classified into three clinical forms:
    • Solitary eosinophilic granuloma: local (usually in older children and young adults)
    • Hand-Schuller-Christian disease: chronic, widespread
    • Leterrer-Siwe disease: malignant, acute, widespread (children under 3 years old).
  • The borders of the lesion are usually well defined but not corticated (punched out). Most often the lesions are multiple with irregular borders and cortical infiltration is observed.
  • Adjacent teeth become loose (“floating”)
  • No expansion of surrounding bone.
