From: Nodular fasciitis: a comprehensive, time-correlated investigation of 17 cases

a, c Strong but focal p16 ((a), case No14) and p27 ((c), case No16) cytoplasmic/nuclear reaction were characteristic for “young” fasciitis. b, d Diffuse strong p16 ((b), case No2) and p27 ((d), case No4) cytoplasmic/nuclear reaction were observed in “old” fasciitis. Scale bar for Fig. 4—100 µm.
