Mom Has This Fast-Growing, Dome-Shaped Pink Bump With a Hard Plug in the Center—What Is It?
It started as a tiny bump.
At first, Mom barely noticed it on her forearm. Maybe it looked like a small pimple, an irritated hair follicle, or an ordinary skin spot.
Then it began growing.
Within a surprisingly short period of time, the bump became a firm, pink or reddish dome. And in the middle was something even more unusual: a hard, crusty-looking plug.
That combination can be alarming.
A rapidly growing, dome-shaped bump with a central hard plug is a classic description of a **keratoacanthoma**, a skin growth that commonly develops on sun-exposed areas such as the arms, hands, face, and neck. However, there is an important complication: keratoacanthomas can look extremely similar to **squamous cell carcinoma**, a common type of skin cancer.
That means this isn't a skin problem that should simply be diagnosed from a photograph or watched indefinitely at home.
If Mom has developed a growth like this, she should arrange a medical evaluation as soon as reasonably possible.
And if the clinic is closed for the weekend, there are some practical things you can do while waiting.
## What Is a Keratoacanthoma?
A keratoacanthoma, often abbreviated as KA, is a rapidly growing skin tumor.
It typically begins as a small spot and can become a firm, rounded or dome-shaped nodule over a matter of weeks. One of its most recognizable features is a **central keratin-filled plug**, which can give the lesion a crater-like appearance.
Keratin is a tough protein found naturally in the outer layer of the skin, hair, and nails.
When large amounts accumulate in the center of the lesion, the result can look like a hard, waxy, brownish, yellowish, or crusty plug.
The surrounding growth may be pink, red, skin-colored, or inflamed.
The appearance can be remarkably distinctive.
But there is a major reason doctors take these lesions seriously.
