title: [A case of composite pheochromocytoma-ganglioneuroblastoma in the adrenal gland with primary hyperparathyroidism].
abstract: We report a case of composite pheochromocytoma-ganglioneuroblastoma in the adrenal gland with primary hyperparathyrodisim. A 55-year-old woman consulted our hospital for an examination of a right adrenal tumor, incidentally found by screening abdominal ultrasound sonography. On the clinical diagnosis of pheochromocytoma in the right adrenal gland from the findings of enhanced abdominal computed tomography, endocrinal examinations and 123I-metaiodobenzyl-guanidine scintigram, right adrenalectomy was performed transperitoneally. Histopathological diagnosis was an adrenal composite pheochromocytoma-ganglioneuroblastoma. This combination of compound adrenal tumor is extremely rare, and to date this case may be the seventh reported in Japan. Moreover, since her serum calcium level and intact parathyroid hormone level were high, so we considered the existence of multiple endocrine neoplasia type 2A. 99mTc-methoxyisobutylisonitrile scintigram and ultrasound of the neck revealed hyperparathyroidism, but medullary thyroid carcinoma was not detected. One year later, she was readmitted for parathyroid tumor excision, and histopathological finding was parathyroid adenoma. We concluded that she had both adrenal composite pheochromocytoma and hyperparathyroidism incidentally.
