[ad. G. histiozyt (Aschoff & Kiyono 1913, in Folia Haematologica: Arch. XV. 386), f. Gr. ἱστίο-ν web, dim. form of ἱστός web, tissue + -cyte.]
A large, highly phagocytic cell found in connective tissue and becoming motile when stimulated; also called adventitious cell, clasmatocyte, macrophage, resting wandering cell. So histioˈcytic a., of or pertaining to, of the nature of, histiocytes.
1924Jrnl. Infectious Dis. XXXIV. 583 These resting wandering cells or histiocytes in all their modifications in the different organs and tissues..are the most active elements in the various inflammatory processes and in particular in tuberculosis. Ibid., It is natural that the lymphocytes should also play an active rôle in the same inflammatory processes and join the polyblasts of histiocytic origin. 1961Lancet 2 Sept. 523/2 The dark red spleen..was unremarkable microscopically except for an occasional large histiocyte in the red pulp with finely vacuolated cytoplasm. 1966[see histiocytosis below].
Also ˌhistiocyˈtosis Path. [-osis], any condition characterized by a proliferation of histiocytes.
1925W. Bloom in Amer. Jrnl. Path. I. 623 For the want of a better name we would suggest ‘lipoid-histiocytosis’ as tending to convey the idea of a process involving the storing of lipoid material by the histiocytes throughout the body. 1953L. Lichtenstein in A.M.A. Arch. Path. LV. 102 The conditions previously designated eosinophilic granuloma of bone, ‘Letter-Siwe disease’ and ‘Schüller-Christian disease’ are interrelated manifestations of a single malady. The name ‘histiocytosis X’ is suggested as a provisional broad general description for this nosologic entity. 1966New Eng. Jrnl. Med. 28 Apr. 929/1 The association of histiocytic proliferations with recurrent infections has been noted in histiocytosis X and in pigmented histiocytosis. |
