A Case of Malignant Metastatic Pheochromocytoma After Eight Years of Primary Diagnosis.

We report a case of a 66-year-old female who presented to the hospital with abdominal discomfort for 3 months. Work-up revealed a 2.4 cm mass in the right adrenal gland. A laparoscopic resection of the adrenal mass was performed and the histopathology was consistent with a pheochromocytoma. Patient was under active surveillance for 8 years, until she developed local recurrence in the right adrenal bed. A right adrenal bed resection and right nephrectomy were performed. Although the tumor margins were positive, none of the sampled lymph nodes (0/6) were positive for metastasis. Patient refused any adjuvant therapy, and was discharged on surveillance from the hospital. A year later, patient was found to have metastatic disease involving her spine, iliac bones, bilateral hips and right dome of the diaphragm. Patient was offered a metaiodobenzylguanidine scan, and positive subsequent treatment with radioactive iodine was discussed with her. However, she denied any further intervention and was made hospice.
