Definition of Reaction, desmoplastic
Medically reviewed by Min Clinic Staff | Updated: January 2026
Reaction, desmoplastic: This term refers to the growth of fibrous or connective tissue. Some tumors elicit a desmoplastic reaction, the pervasive growth of dense fibrous tissue around the tumor. Scar tissue (adhesion) within the abdomen after abdominal surgery is another type of desmoplastic reaction.
"Desmo-" comes from the Greek "desmos" meaning "a fetter or band" and "-plastic" is also borrowed from the Greek, from "plassein" meaning "to form" = to form a band or fetter.
