22) Dermatographia
Dermatographia is a rare skin condition characterized by the spontaneous appearance of blisters, rashes, and other skin lesions in random patterns. The term “dermatographia” combines elements from dermatology and graphology, the study of handwriting. Often mistaken for stigmata or maculopapular erythema, dermatographia differs in that it is not linked to religious images but rather represents an abnormal pattern of skin irritation. Individuals with dermatographia may experience unexpected blisters or rashes without an obvious cause.
Sometimes, these skin spots can be itchy or sore. Dermatographia can happen to anyone, but it’s most common in kids between 5 and 15 years old. Scientists aren’t sure what causes it; some think it might be a harmless genetic trait, while others think it could be related to poor nutrition or environmental factors like pesticides and air pollution. People with dermatographia might also be more likely to get eczema or psoriasis. There’s no cure for dermatographia right now, but doctors can help manage symptoms like itching and discomfort with ointments.
