What Is The Difference Between Hypertrophic Scarring And A Keloid
The area affected: Hypertrophic scars are raised scars that do not spread beyond the boundry of the original scar. A keloid is a scar that continues to grow, extending well outside the boundary of the original scar site. That is, it spreads into areas of previously normal non-scarred skin. ...Read moreSee 2 more doctor answers
Hypertrophy is an increase in size of an organ or tissue, or a particular part of the body. Examples include muscle hypertrophy due to lifting weights, ventricular hypertrophy (enlargement of a ventricle of the heart) due to high blood pressure or other heart disorders, or prostatic hypertrophy (enlargement of ...Read more
Stable vs growing : An adhesion is a scar anywhere in the body (not just the skin) that physically causes two structures to become adherent and is a common cause for bowel obstruction. They remin stable in size over time. Keloids are scars that have a tendency to grow over time and more likely occur on the skin. ...Read moreSee 1 more doctor answer
Big difference. : Moles are benign lesions that stable over time but may grow slowly. If they suddenly change, a biopsy may be recommended. Keloids grow and be one larger over time and generally associated with trauma or injury or inflammation. The keloid in the photo has been treated whereas the other smaller pigmented lesions appear more similar to moles. ...Read moreSee 1 more doctor answer
Same thing: All injuries heal with a scar, which is a normal healing process. Occasionally scars develop abnormally and become thick and hard - this is called a hypertrophic scar. A scar that grows beyond the boundaries of the wound is a keloid scar. ...Read more
Same/Opposite Sides: Ipsi means "on same side". Contra means "on opposite side". Lesion refers to an abnormal/unhealthy tissue (of whatever original type), tissue which is damaged in some way, including potential risk of spreading damage to adjacent tissue(s). ...Read more
Two important facets: Acne treatment consists of many different modalities (cleansers, antibiotics, exfoliants, retinoids, light based treatments, injections etc...) to control the disease over time and minimize complications, one of the worst being permanent scarring. Acne scar treatment is also multi modality including skin resurfacing treatments (mechanical, chemical and laser), fillers and surgical excision. ...Read more
Infection vs not: A pimple is a tiny infection in a pore. The white stuff inside is pus. It's basically a very small abscess. There are many different kinds of cyst, but basically it's a walled off sac of fluid, but not an infection. Cysts can sometimes go away on their own, sometimes need surgery. Acne is generally treated topically (soaps and creams) and sometimes with oral antibiotics. ...Read more
The same: Anytime the skin is penetrated or opened a wound is created. This can vary from a puncture wound to a large deep opening.

What is the difference between acne scars and acne pigmentation? (sorry if that's not how the pigmentation is called)
Good question!: Acne causes inflammatory (and sometimes infected) cysts; if the surrounding tissues are damaged (enough) by squeezing or more severe infection, scars can result. Even if scars are not caused, inflammation can cause skin pigment cells (melanocytes) to be stimulated, making the surrounding skin darker. This post-inflammatory hyperpigmentation can leave blotches and discolorations even without scars. ...Read moreSee 1 more doctor answer
Color: Certainly, blackhead looks black and whitehead look white, but it's not that simple. Blackhead and white head both are mild/early forms of pimple/acne. Blackhead devolops when the content of pimples, mostly, sebum, expose to air and oxidized. It turns to dark brown or "black" color. Whitehead is when sebum enclosed by epidermis(i.e., not exposing to air) and showing yellow or "white" content. ...Read moreSee 1 more doctor answer

Thanks for asking!: A wart looks like a pimple that is very 'ragged' on top and it typically does not itch or respond to most topical products (except liquid nitrogen and salicylate acid) a pimple is usually filled with pus or some type of cellular debris. This lesion will typically respond to many topical products. Are these on your face? Are you concerned about seed warts and acne? ...Read more
Dialysis shunts.: A shunt is a term for the connection that shunts blood from an artery to a vein, bypassing the microscopic network in the tissues that normally connect them. This allows a high blood flow access for pulling blood from the body to the dialysis filter. A fistula is a shunt that has a direct connection of a native artery and native vein, rather than using an artificial tube to make the connection. ...Read moreSee 1 more doctor answer
How do I identify Peyronie's disease scar tissue or plaque? And what is the difference between the 'scar tissue' and 'plaque'?
Same, but ...: Plaque is a specific descriptive term to denote the shape of the scar of Peyronie's disease, and scar tissue is a general term to describe the common microscopic picture of healing/healed tissue after injury by various reasons, resulting in disruption of local circulation and cell arrangement. The plaque may widely vary in size & shape so some plaques are barely palpable, and others, obvious. ...Read more
