The process of forming ulcers or open sores on the skin or mucous membranes.
From Latin exulcerare (to cause to ulcerate), combining ex- (out) and ulcerare (to ulcerate), derived from ulcus (ulcer). The term evolved from medical Latin to describe the progressive damage and breakdown of tissue.
This word reveals how Latin medical terminology preserves precise descriptions of disease — 'exulceration' specifically means the ongoing process of ulcer formation, not just the ulcer itself, showing how ancient physicians categorized stages of tissue damage.
