CASTILLO C, Octavio A et al. Malignant pheochromocytoma treated with minimally invasive surgery. Rev Chil Cir [online]. 2014, vol.66, n.1, pp.63-67. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262014000100010.

Introduction: Pheochromocytoma is a tumor derived from chromaffin cells that produces cathecolamines. Malignant pheochromocytomas are extremely rare. Aim: To describe 2 cases of malignant Pheochromocytoma treated with pure laparoscopic and robot assisted surgery. Clinical cases: Two female patients, 31 and 51 years of age, presented with a history of high blood pressure and abdominal pain. Radiologic and metabolic studies confirmed the diagnosis of Pheochromocytoma in both patients. A pure laparoscopic approach was performed in the first patient while a robotic assisted laparoscopy was done in the second patient. In both cases, adrenalectomy with in bloc nephrectomy was performed due to compromise of the renal sinus. There were no complications or conversion to open surgery. Histopathology confirmed the diagnosis of malignant Pheochromocytoma with metastasis to regional nodes and negative surgical margins. At follow-up, there is no evidence of recurrence. Conclusion: Malignant Pheochromocytoma can be treated with minimally invasive surgery, with morbidity and oncological outcomes similar to open approach.

Palabras clave : Pheochromocytoma; malignant Pheochromocytoma; adrenal tumor; laparoscopy; robotic surgery.
