histiocytosis of langerhans cells (class 1 histiocytosis) consists of a range of clinical manifestations, including bone eosinophilic granuloma, hand-schüller-christian syndrome, and letterer-siwe disease. these syndromes represent a spectrum of severity and prognosis of an underlying disorder which is usually sporadic. this report describes three cases in one family, who developed the disease ...

Resolution rate and qualitative characteristics of healing were studied in 71 osseous lesions of histiocytosis X. Rates of healing, as assessed planimetrically and by vertebral body-height measurement, did not differ significantly among lesions that were treated with chemotherapy alone, chemotherapy plus radiation, radiation alone, or those that received no treatment. Lesions of Letterer-Siwe d...

Langerhan's Cell Histiocytosis (LCH) is disorders which include abnormalities that result from abnormal proliferation of langerhan's cells or their precursors. LCH is clinically classified into three types-eosinophilic granuloma, Hand Schuller Christian disease and Abt-Letterer- Siwe disease. It is usually manifested in childhood as well as in adulthood. The clinical manifestations are the resu...

Of 76 children with histiocytosis X 18 had orbital involvement, and four developed additional neuro-ophthalmic complications. No instance of intraocular involvement was detected. Among those patients with ophthalmic involvement the main problems were bilateral or unilateral proptosis, ptosis, papilloedema, optic atrophy, and seventh nerve palsy. Only one patient developed a severe visual defect...
