Fig 2 A, Histopathology (case 1) reveals, at low power, epidermal atrophy, significant pandermal fibrosis with compaction and homogenization of collagen bundles, entrapment of eccrine glands high in dermis, and adipose tissue changes. Note parallel array of compacted collagen bundles in papillary dermis. B, Close-up view of eccrine coils in upper dermis highlights loss of perieccrine fat pad and surrounding dermal fibrosis. (Hematoxylin-eosin stain; original magnification: ×100.) C, Subcutaneous tissue shows diminutive fat lobules composed of small adipocytes in hyalinized and highly vascularized stroma. (Hematoxylin-eosin stain; original magnification: ×100.) D, Fontana-Masson stain reveals decreased basal keratinocyte pigmentation. Note epidermal atrophy and lack of superficial perivascular inflammation. (Original magnification: ×40.)
