Summary

A 45-year-old woman was diagnosed as having multiple endocrine neoplasia type 2A in 2014. She had bilateral pheochromocytoma, medullary thyroid carcinoma and biopsy-proven cutaneous lichen amyloidosis in the interscapular area. She underwent bilateral adrenalectomy; following which, she achieved clinical and biochemical remission. She was planned for total thyroidectomy at a later date; however, she was lost to follow-up. She presented to us again in December 2016 with abdominal pain. Examination revealed hypertension with postural drop. Positron emission tomography scan showed Ga⁶⁸ and fluorodeoxyglucose (FDG)-avid suprarenal, hepatic, peritoneal and mesenteric masses with abdominal lymph nodes. Twenty-four-hour urinary metanephrines/normetanephrines were elevated. Serum calcitonin was as high as it was 2-1/2 years ago. Ultrasonography-guided fine-needle aspiration cytology (FNAC) from the liver mass revealed neuroendocrine cells that did not stain for calcitonin. Hence, a diagnosis of metastatic pheochromocytoma was made. She underwent total thyroidectomy and was started on cyclophosphamide, vincristine, dacarbazine-based chemotherapy regimen.
