Sporadic Retroperitoneal Hemangioblastoma: Report of a Case and Review of the Literature

Figure 3

Histological examination demonstrated a well circumscribed and cellular lesion with a thin fibrous capsule ((a), H&E stain, 50x). The lesion was composed of sheets of cells with interspersed abundant capillaries and scattered large vessels ((b), H&E stain, 100x). At low power, patchy areas resembled a capillary hemangioma ((c), H&E stain, 100x). High power examination showed large neoplastic cells with foamy cytoplasm and irregular hyperchromatic nuclei, mimicking the native adrenal cortical cells, admixed with benign-appearing capillaries ((d), H&E, 400x). Native adrenal cells ((e), H&E, 200x).
