We present a unique case of necrobiosis lipoidica (NL) arising within a port-wine stain (PWS), which, to our knowledge, has not been previously reported. NL is a rare granulomatous disorder often associated with diabetes mellitus, characterized by chronic inflammation and microvascular dysfunction. PWS, a congenital vascular malformation, results from defective endothelial differentiation and capillary malformation.
The post Necrobiosis lipoidica arising in a port wine stain treated with topical ruxolitinib appeared first on American Osteopathic Association.
