Description: At higher magnification, distinct lipomembranous changes can be appreciated as a feathery, eosinophilic lining to the thickened wall of the microcysts within the subcutaneous fat.
Comments: This condition is commonly associated with vascular insufficiency, especially stasis changes. A frequent clinical presentation is an "apple-core" or "inverted champagne bottle" appearance to the lower legs. The differential diagnosis would include other forms of mixed septal and lobular panniculitis, including factitial etiologies.
