Medical disclaimer: The images shown with this article are dramatic visual examples and cannot be used alone to diagnose a medical condition. A healthcare professional should evaluate any unusual, painful, infected, or rapidly changing skin lesion.

When an Ordinary Skin Problem Takes an Unexpected Turn

The skin is the body’s largest organ, and it can sometimes develop changes that look far more frightening than people expect.

Redness, swelling, blocked pores, open lesions, dark material, unusual bumps, or even insects attached to the skin can all have very different causes. Some may be relatively minor, while others can indicate an infection, an inflammatory condition, or an infestation requiring prompt medical attention.

The images accompanying this story show several extreme and unusual-looking skin situations, including lesions around the face and scalp, a larva-like structure emerging from inflamed skin, insect attachment, and heavily affected areas containing numerous dark plugs.

But an important point is often overlooked:

A shocking appearance does not automatically reveal the diagnosis.

Many different skin conditions can look similar on camera, and some viral medical images are also edited, staged, or presented without enough clinical information to determine exactly what happened.
