Disseminated is a term used in medicine to describe a widespread or widely dispersed process in the body.
From the Latin disseminatus, meaning "scattered."
Disseminated processes usually involve multiple lesions in various organs or tissues. For example:
-
Disseminated tuberculosis - when tuberculosis lesions are observed in the lungs and other organs at the same time.
-
Disseminated intravascular coagulopathy is a blood clotting disorder in which microthrombi form in many capillaries.
-
Disseminated herpes infection is the spread of the herpes simplex virus throughout the body, affecting various organs.
Thus, disseminated means that the process has a widespread, multiple and scattered nature of the lesion. This term is widely used in medicine to describe such conditions.
