Several asymptomatic, erythematous papules and plaques had appeared on the hands of an otherwise healthy 11-year-old girl. The personal and family medical histories were noncontributory. A punch biopsy from the largest lesion on the palm confirmed the clinical diagnosis of localized granuloma annulare, a self-limited inflammation of the dermis.
This 30-year-old man complained of "perpetually dry" feet. He was in good health, took no medications, and had a noncontributory social and family history.
The patient had 3 circular healing wounds of varying diameters on the lateral and inner aspects of his upper left arm. The patient volunteered that he had inflicted these wounds with a cigarette in an attempt to tattoo himself to symbolize his "crazy life." (He was right-handed.) "Smiley faces" had also been tattooed on his hand with a lighter. There were no tattoos, body piercings, or body mutilation other than those mentioned.

A 51-year-old woman is seen because of burning at the site of entry of a urethral (Foley) catheter. The catheter had been placed perioperatively for a cholecystectomy. No history of genitourinary difficulty or trauma to the area.
