Oncocytic adrenocortical tumor with uncertain malignant potential in pediatric population: A case report and review of literature

Figure 1 The ossification center indicates 3-year-old bone age changes.

Figure 2 Complete tumor capsule, tumor size 5. 5 cm × 5.0 cm × 3.0 cm, no definite capsular invasion and no definite vein invasion were found.

Figure 3 Eosinophils were predominant; visible wide cell atypical; no definite necrosis was found; no definite capsular invasion was found; no definite vein violation; visible focal sinus infiltration; some calcification is visible. A: Typical eosinophilic changes (hematoxylin-eosin staining, image at 400 × magnification); B: This is a focal sinus infiltration of eosinophils (hematoxylin-eosin staining, image at 400 × magnification). Orange arrow: Focal sinus infiltration; C: Calcification: Blue fine particles aggregate (hematoxylin-eosin staining, image at 400 × magnification). Blue arrow: Calcification; D: Mitotic images count 1/10 hibernation-promoting factor (hematoxylin-eosin staining, image at 400 × magnification). Green arrow: Mitotic nuclear division.
