A medical condition where many tumors called sarcomas develop in different areas of the body.
The patient was diagnosed with sarcomatosis after several tumors were found during the examination.
Sarcomatosis is formed from "sarco-" (from Greek "sarkos", meaning flesh) and "-osis" (from Greek "osis", meaning a condition or disease). The term refers to a condition involving fleshy tumors or growths, particularly those of a malignant nature.
Think of 'flesh' ('sarco-') being affected by a 'condition' ('-osis') — that's why sarcomatosis refers to a disease involving fleshy tumors.
