Etymology: Histiocytomas is simply the plural of histiocytoma, so the story belongs to the two parts it is built from. "Histiocyte" combines the Greek "histio-", from "histos", meaning tissue or web, with "-cyte", from Greek "kytos", meaning hollow vessel or cell. Histiocytes are the immune cells that wander through tissue and engulf debris, and the name reflects their location in the body's tissues rather than in the blood. The suffix "-oma", from Greek, marks a swelling or tumor, which is why the same ending appears in words like lymphoma and melanoma. Put together, histiocytoma names a growth made of these tissue cells. The plural form simply refers to more than one such growth. The word is a modern scientific coinage built from classical Greek parts, so its elements carry the original meanings, but the compound itself was assembled for medical use rather than inherited from ancient writers.
