Microscopic (histologic) description
- Thickening and hyalinization of connective tissue of deep dermis, subcutaneous fat and muscular fascia, with perivascular and focal interstitial lymphocytic and plasma cell infiltrate in subcutaneous fat
- Frequent atrophy of adnexal structures, increased fibroblasts, thickening and luminal narrowing of small vessels, blunting of dermal-subcutis interface, diminished elastic tissue
- Often atrophy of epidermis, mucin deposition
- Variable dystrophic calcification of blood vessels
- Control biopsy from adjacent normal skin is helpful

Negative stains
- Immunoglobulins
Differential diagnosis

- Eosinophilic fasciitis: thickening of deep fascia only
- Lichen sclerosus et atrophicus, acrodermatitis chronic atrophicans
