Immunohistochemistry of FOSB and CAMTA1. a Tumor cells of PHE showed diffuse and strong nuclear expression of FOSB (Case 3). b Tumor cells of PHE showed diffuse and strong nuclear expression of FOSB. This section was obtained from a bone lesion and underwent decalcification. Positivity of FOSB was preserved after the decalcification process (Case 4). c Tumor cells of KS showed limited and weak FOSB expression. Its positivity was apparently different from that in PHE. Epidermal keratinocytes and endothelial cells in the background were positive for FOSB. These findings should be carefully distinguished from true FOSB positivity in tumor cells (Case 22). d Tumor cells of EHE exhibited diffuse and strong nuclear expression of CAMTA1 (Case 9)
