Hematohidrosis in 15th Century Renaissance Art and a Review of Modern Literature.

Hematohidrosis, or hematidrosis, is a rare medical condition characterized by blood oozing from the intact skin in the absence of a bleeding problem.[1] Prior to modern-day medical literature, these phenomena had been captured in Renaissance and also present-day artwork. While the purpose of medical literature is to aid healthcare professionals and patients in the better understanding and treatment of disease, a significant proportion of Renaissance art commissioned by the church depicted scenes from the Bible, for the purposes of a visual depiction of key events to promote teachings of the faith, and to encourage devotion to God.
