RESUMO
INTRODUCTION: Cavernous hemangioma of the adrenal gland is a rare non-functioning benign neoplasm. PRESENTATION OF CASE: A 62-year-old woman with chronic obstructive pulmonary disease was diagnosed as having an incidental non-functioning adrenal tumor. Because of the impossibility of ruling out the presence of malignancy, conventional surgical resection was carried out. The histopathology revealed a 12.5cm×11.5cm×8cm adrenal mass with large and lacunae vascular spaces lined with mature endothelial cells. These findings were compatible with cavernous hemangioma. DISCUSSION: The majority of patients in the literature underwent surgical resection due to the impossibility of excluding malignancy, because of related symptoms in patients with large masses, or because of the risk of spontaneous tumoral rupture. CONCLUSION: These tumors are quite infrequent. Due to the low frequency and the lack of specific symptoms, most adrenal hemangiomas are diagnosed postoperatively.
