Schiff (PAS)-positive and diastase-resistant (Figures 1 and 2), Congo-red-positive (Figure 3), apple-green-birefringent material characteristic of amyloid. Similar amyloid deposits were also evident to a lesser extent surrounding follicular epithelium within the mid-dermis.
Accumulation of periodic acid Schiff with diastase (PASD)-positive material, representing amyloid, within follicular connective-tissue sheaths and within the wall of a small blood vessel. PASD 100x.

Positive staining of amyloid within follicular connective-tissue sheaths and, more weakly, within the basement membranes of an eccrine coil and small blood vessel. Congo red 100x.
