Digital lesion: (A) relationship between pacinian corpuscle (P) and nerves (arrows); these two structures
are interspersed with vascular and nervous twigs (double arrowheads) with surrounding loose connective
and fatty tissues; (B) normal structures of pacinian corpuscle are seen (outer capsule continuous with
perineurium, lamellated inner and outer core, nerve fibers terminating center of inner core)

Digital lesion following dog bite: (a) diffuse swelling;
(b) pacinian hyperplasia with inner nerve fiber surrounded
by concentric fibrous lamellae; (c) inner core cells are S100+;
(d) outer lamellae are vimentin+; (e) outer core cells are EMA+
