Eponym:

The subcutaneous tissue of the perineum is eponymously known as Colles’ fascia, named after the Irish surgeon and anatomist Abraham Colles (1773–1843). Colles was born in Ireland and pursued his medical education at the University of Dublin and the Royal College of Surgeons in Ireland, where he later served as a professor of anatomy and surgery.[2] His early exposure to anatomical literature sparked a lifelong interest in anatomy, leading to significant contributions to both surgical practice and anatomical education.

Scientific Contributions:

In 1811, Colles published A Treatise on Surgical Anatomy, a work that included a detailed description of the fascial layers of the perineum.[2] He emphasized the continuity of the perineal fascia with the membranous layer of the abdominal fascia and the fascia of the external genitalia, and he recognized its importance in limiting the spread of blood and urine following urethral injury.[2]

​

Subsequent anatomists expanded upon Colles’ observations. In 1854, John Struthers noted that the use of multiple terms for this fascial layer—such as deep superficial fascia or membranous superficial fascia—led to confusion among students and clinicians.[3] Struthers advocated for the adoption of the concise and specific term “Colles’ fascia,” a designation that has since remained in common anatomical usage.[3]
