ADRENAL SCHWANNOMA IN CHILD:A CASE REPORT

　14歳，女児．腹痛の精査中，後腹膜に腫瘤を認めた．MRI，血管造影等より左副腎腫瘍と診断し，摘除術を施行．摘出標本は弾性硬，75×55×50mm,115gで，割面は乳白色で均一であった．病理にてAntoni A型の副腎神経鞘腫と診断された．現在まで再発を認めていない．副腎を原発とする神経鞘腫は珍しく，国内で5例目，また小児例としては本邦初と思われる．

A 14-year-old girl with abdominal pain was found to have a left retroperitoneal mass on CTscan. An adrenal tumor was suspected with further study by MRI and angiography. The removed tumor (115 g in weight and 75 x 55 x 50 mm in size) was firm but elastic in consistency. The cutsurface was homogenously milky white in color. Microscopic examination confirmed the diagnosis of Schwannoma (Antoni A type) originating from the adrenal gland. This type of tumor has been considered to be rare and only four cases have been reported in Japan. To our knowledge, this is the first child case.
