Report of two rare cases of adrenal incidentalomas with different origins: revisiting pathological and radiological findings with a short review of the literature

Background Adrenal tumors can be detected incidentally in 4 to 8% of patients radiologically. Adenomas, pheochromocytomas, and adrenocortical carcinomas represent the most common tumors of the adrenal glands. Rare histopathological findings are uncommon. We aimed to report two rare primary adrenal tumors diagnosed initially as incidentalomas to identify clinical characteristics, management, and clinical outcomes after treatment. Case presentation The first case was a 52-year-old man presented with an incidentally discovered locally advanced primary adrenal angiosarcoma. The patient was managed surgically with no adjuvant therapy. The patient was followed up for 3 years without evidence of local recurrence. The second case was a 63-year-old woman, presented with an incidentally discovered primary diffuse B-cell lymphoma of the left adrenal gland. She was treated by adrenalectomy. Later on, adjuvant six cycles of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy were given. After 6 months follow-up, the patient was alive and disease-free. Conclusion The diagnosis of adrenal tumors increased nowadays because of the widespread use of imaging studies, though rare pathologies should be taken into consideration.
