Abstract

New pigmented lesions with alarming properties should trigger the responsible physician to perform diagnostic procedures including biopsies, blood tests, and endocrinological evaluations. A unique pigmented dermatosis of unknown etiology, known as terra firma forme dermatosis, creates a cosmetic disturbance that might mislead experienced physicians and trigger unnecessary and expensive workups when all that is needed is a firm rubbing with 70% alcohol-impregnated applicators. We present a 17-year-old girl with such a lesion and discuss the diagnostic possibilities.
