Linear morphea is a distinct form of morphea that occurs as a linear band usually with a single unilateral distribution. The lower extremities are most often involved. This dermatosis appears as a linear induration not necessarily related to the derm induration. We report herein a case of 20-year-old Iranian girl who had a linear sclerotic patch on right lower extremity with clinical and pathologic diagnosis of linear morphea. Several perforating papules appeared on the lesion after 6 months, confirmed as perforating dermatosis by the biopsy.
