Inflammatory morphea mimicking an acquired port-wine stain initially treated with pulsed-dye laser

The early inflammatory lesions of morphea may present with erythema or violaceous patches and plaques before evolving into areas of sclerosis. They have been misdiagnosed as acquired port-wine stains (PWSs). We report a previously well 7-year-old Chinese girl presenting with early facial morphea mimicking an acquired PWS with unusual histologic features of perineural inflammation. The presence of cutaneous perineural inflammation may be seen in a small percentage of cases of morphea and appears to be a feature of early inflammatory morphea. We report this case to highlight the importance in recognizing this entity and summarize the reported cases of inflammatory morphea mimicking acquired PWSs.
