We report a patient presenting with bilateral lacrimal gland involvement and perioptic nerve sheath lesions due to Langerhans cell histiocytosis (LCH) invasion. LCH is a rare multisystemic disease characterized by a clonal proliferation of Langerhans cells. All organs may be involved with a clinical spectrum ranging from a solitary bone lesion to a severe life-threatening multisystem disease. Osteolytic orbital bone lesions with extension into the adjacent orbital soft tissues have been described. To our knowledge, lacrimal gland involvement has probably been described only once before. Perioptic nerve lesions are also very rare, having been described only three times before.
