Incarceration for excoriation.

A thirty-six-year-old man experienced acute, severe, generalized pruritus. His scratching was erroneously interpreted as lewd and indecent behavior. He was arrested. Results of the history and physical examination led to the diagnosis of fiberglass dermatitis, which prompted a dismissal of the charges. Although many societies have looked askance at persons with certain skin diseases (such as leprosy) and at scratching in public since at least biblical times, we are not aware of any prior reports of incarceration for excoriation.
