Crohn's disease can manifest on the skin in various ways. While the exact appearance can vary depending on the specific skin condition, some common symptoms include:
Erythema Nodosum
Erythema nodosum is a painful, red, and tender lump that usually appears on the shins and sometimes on the thighs or arms.
Pyoderma Gangrenosum
Pyoderma gangrenosum is a rare skin condition characterized by painful ulcers that can appear on the legs, arms, and sometimes on the face. These ulcers can be shallow or deep, and they often have a purplish or red border.
Psoriasis
Some people with Crohn's disease also develop psoriasis, a common skin condition that causes thick, scaly patches on the skin. Psoriasis can appear anywhere on the body, but it is most common on the elbows, knees, scalp, and lower back.
Other Skin Conditions
Other skin conditions associated with Crohn's disease include:
- Acne
- Nail changes
- Oral ulcers
- Acanthosis nigricans
It's important to note that not everyone with Crohn's disease will experience skin symptoms. If you have any concerns about your skin, it's essential to consult a dermatologist.
