Operative and pathological views. (a) and (b) show the circular craniectomy and the complete excision of the mass. Observe that the dura mater does not seem to be infiltrated or damaged; (c) hematoxilin and eosin preparation from the mass showing multiple plasmatic cell infiltration; (d) hematoxilin and eosin preparation from the lymph node biopsy with peripheral follicular proliferation and hyalinization of the vessels (black arrow) and the presence of plasma cells. These are the typical findings of Castleman’s disease.
