Objectives: To describe a case of a giant benign abscessed pheochromocytoma due to its low incidence. Clinical case: A fifty-three year old male patient, with current illness since august/2013, characterized by hyporexia, astenia, abdominal pain on right hypochondrium and 39°C fever with 12 kg weight loss in a 4 month period, was referred to this medical center. During hospital stay the patient presents elevated blood pressure and palpitations. An abdominal US is performed twice with the following findings: space-occupying lesion (SOL) on liver segments V and VI and a grade II right renal parenchymal lesion. A double contrast CT-Scan of the abdomen and pelvis is performed and reports a neo-proliferative right suprarenal mass. The 24-hour urinary catecholamine test result was high. α and β blocking with doxazosin and propranolol was initiated. Soon after he was operated: right adrenalectomy with lymph node resection and right nephrectomy. Grossly an adrenal tumor of 25 cm diameter is observed, with fetid, purulent inside content. Culture of purulent content reported Salmonella sp. Biopsy was concluded as cystic-abscessed pheochromocytoma with no suggestive findings of malignancy. Conclusion: Pheochromocytoma is a low prevalence neuroendocrine tumor. Most are less than 6cms, with few case reports of pheochromocytomas more than 20 cm and very few of abscessed lesions, both commonly associated with malignancy. The definitive diagnosis is histological. The treatment is surgical resection.
