Abstract The dentist may play an important role in establishing the diagnosis of histiocytosis X, since the disease often manifests itself initially in the oral cavity. Some of the more important clinical findings that should arouse the clinician's suspicion include (1) marked periodontal disease or cysts of unknown etiology which do not respond to ...

Histiocytosis X of the Thyroid Gland
Tumori Journal, 1996Histiocytosis X rarely involves the thyroid gland and occurs as one of the unusual manifestations of systemic diseases. Diagnosis is based on the identification of the Langerhans' cells in an appropriate background. We report a case of histiocytosis X confined to the thyroid gland that represents the primary manifestation of the disease.

Chemotherapy of Histiocytosis-X
Hematology/Oncology Clinics of North America, 1987This article discusses the efficacy of various chemotherapeutic agents in the treatment of histiocytosis-X. Although these agents alone and in combination have improved the prognoses for children with histiocytosis-X, the need for more effective methods of treatment still exists.

Prostaglandins in Histiocytosis-X: PG Synthesis by Histiocytosis-X Cells
American Journal of Clinical Pathology, 1981Histiocytosis-X cells were obtained at autopsy from the lungs and lymph nodes of a patient who died of the disseminated infantile form of this disease (Letterer-Siwe disease). The ability of these cells to synthesize and release prostaglandins was investigated in culture, by prelabeling the cell lipids with [14C] arachidonic acid and measuring the ...

Immunotherapy of Histiocytosis-X
Hematology/Oncology Clinics of North America, 1987This article focuses on the interaction of histiocytosis-X and the immunotherapeutic agent, suppression. Studies with this and other agents have presented us with invaluable insights into the nature of histiocytosis-X.

Immunobiology of Histiocytosis-X
Hematology/Oncology Clinics of North America, 1987Recent laboratory investigations of patients with histiocytosis-X and their pathologic tissues demonstrate the close immunologic relationship between the Langerhans-like cells of these patients and normal epidermal Langerhans cells of the mononuclear phagocytic system. A deficiency of a peripheral blood lymphocyte subpopulation is seen in histiocytosis-

The Cytology of Langerhans Cell Histiocytosis (Histiocytosis X)
Cytopathology, 1991The cytomorphology of 13 cases of Langerhans cell histiocytosis is described. the most striking features were the presence of intranuclear clefts, pale nuclei and inconspicuous nucleoli, together with ample pale cytoplasm, only slight cellular pleomorphism, and an admixture of varying numbers of eosinophils, macrophages and degenerated cells.In 13 of ...
