Detection of a unicentric type of Castleman-like mass at the site of adrenal grand: A case report and review of literature

Figure 1 Abdomen computed tomography-scan demonstrating a 4. 2 cm mass in the left adrenal. A: Computed tomography (CT) plain scan showed the mass in the left adrenal; B: CT enhancement scan showed the mass in the left adrenal with no enhanced uniform.

Figure 2 Pathological diagnosis of castleman disease was made by the analysis of morphological pattern and immunohistochemical markers. A: hematoxylin-eosin (HE) (40 × magnification) staining showed a large number of enlarged lymphoid follicle scattered in the distribution; B: HE (100 × magnification) staining showed hyperplasia and wall thickening of the small blood vessels; C: Immunohistochemical staining (100 × magnification) showed CD20 was ubiquitously expressed; D: Immunohistochemical staining (HE 100 × magnification) showed CD21 was ubiquitously expressed. CD: Castleman disease; HE: Hematoxylin-eosin.
