多発性内分泌腺腫症2型に合併した複合型副腎髄質腫瘍

COMPOUND ADRENAL MEDULLARY TUMOR ASSOCIATED WITH MULTIPLE ENDOCRINE NEOPLASIA OF TYPE 2: A CASE REPORT

　74歳，女性。18年前に甲状腺の髄様癌の摘出術を受けている。最近，めまい，嘔吐を訴え，血液・尿中のカテコラミンの増加と両側副腎の腫瘤を指摘され，両側副腎摘出術を施行した。病理学的に左側は良性の褐色細胞腫であったが，右側は良性の褐色細胞腫と良性の神経節腫が共存しており，複合型副腎髄質腫瘍と診断した。

A 74-year-old woman, who had received thyroidectomy due to medullary carcinoma 18 years before, was found to have bilateral adrenal tumors. The surgical removal of both adrenal glands revealed that the right adrenal tumor consisted of benign pheochromocytoma and ganglio-neuroma, while the left adrenal tumor was a usual benign pheochromocytoma. Therefore, the diagnosis of com-pound adrenal medullary tumor associated with multiple endocrine neoplasia of type 2 was established.
