副腎神経節神経腫の2例

TWO CASES OF ADRENAL GANGLIONEUROMA

　副腎神経節神経腫の1成人例および1小児例を経験した．本疾患のほとんどは無症状，内分泌非活性であるが，自験例では尿中カテコラミンの軽度上昇を認めた．なかでも成人例においては不定愁訴を自覚し，部位別採血において腫瘍より軽度のカテコラミン産生が認められ，術後に改善を認めたことより，本疾患でも軽度内分泌活性の場合があることが示唆された．自験例は本邦報告第31,32例目（成人例26例目，小児例6例目）にあたる．

Case 1 was a 38-year-old female, who complained of tachycardia, palpitation, hyperidrosis, headache and general fatigue. Ultrasonography revealed a left adrenal tumor incidentally. Urine catecholamine excretion were slightly high. CT scan revealed low density mass at left adrenal gland and angiography suggested no malignancy. Through transabdominal approach left adrenal tumor was removed. The tumor was 95 × 65 × 45 mm in size and 145 g in weight. Histological diagnosis was ganglioneuroma arising from the adrenal medulla. Case 2 was a 5-year-old girl, who complained of obesity.
