Lichen aureus is a pigmented purpuric dermatosis that tends to occur on the lower extremities, and linear morphea is an inflammatory disease of the dermis and subcutaneous fat that leads to a scarlike induration. We present a pediatric case of linear morphea developing in the same anatomic distribution as prior lichen aureus. Due to the possible progression of lichen aureus to morphea described herein and the difficulty in diagnosing early morphea, close followup may be considered for pediatric patients who present with this pigmented purpuric dermatosis. e92 | Pediatric Dermatology BRIEF REPORT To date, there has been one case report of a 55-year-old man with morphea occurring in the identical distribution of a previously resolved pigmented purpuric dermatosis. 2 It has been hypothesized that the increase in venous capillary pressure and fragility, features of PPD, results in the extravasation of red blood cells and the leakage of growth factors. The stimulation of fibroblast activity by growth factors could account for the excessive collagen deposition and fibrosis seen in morphea. 2,3 Due to the possible progression of lichen aureus to morphea as described above, close follow-up may be considered for pediatric patients who present with this pigmented purpuric dermatosis. 4
