Morphology

histiocytosis = histiocyte (transparent) = histiocyte + osis

Standard medical derivation: the disease/condition suffix '-osis' is added to 'histiocyte' to indicate a disorder involving those cells.

Etymology

Histiocytosis breaks into histo- meaning 'tissue' and -cytosis meaning 'a condition of cells', with cyte like the common word 'cell'. So it names a condition where certain tissue cells, a kind of white blood cell, are too many, which explains the modern medical meaning.
