Morphology

histiocytic = histiocyte (transparent) = histiocyte + cyt + ic

Formed by standard adjectival suffixation from the noun 'histiocyte', so its meaning is directly 'relating to histiocytes'.

Etymology

Histiocytic comes from parts meaning 'tissue' (histio-) and 'cell' (-cyte), so you can think of it as 'tissue cell'. A histiocytic condition is one that involves tissue cells, often a type of immune cell in the body.
