Histiocytosis X: diagnosis by electron microscopy. 1981

M E Schwartz

The three histiocytosis X diseases are often initially misdiagnosed because of their frequently slow and insidious onset. Cutaneous lesions are commonly seen and are often the initial manifestation. The atypical histiocytes in all clinical types of histiocytosis X contain characteristic intracytoplasmic granules that can be seen with the electron microscope. Skin biopsy is thus a simple and rapid method for confirming the diagnosis of histiocytosis X.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D004803	Eosinophilic Granuloma	The most benign and common form of Langerhans-cell histiocytosis which involves localized nodular lesions predominantly of the bones but also of the gastric mucosa, small intestine, lungs, or skin, with infiltration by EOSINOPHILS.

D006646	Histiocytosis, Langerhans-Cell	A group of disorders resulting from the abnormal proliferation of and tissue infiltration by LANGERHANS CELLS which can be detected by their characteristic Birbeck granules (X bodies), or by monoclonal antibody staining for their surface CD1 ANTIGENS. Langerhans-cell granulomatosis can involve a single organ, or can be a systemic disorder.
