Of the 90 cases of @entity459 surgically treated in our department over the last decade (1975-1985), ten cases had a mediastinal @entity3243 . In only two of these @entity1 was a median sternotomy required for excision of the mediastinal @entity652 . Three of the ten @entity1 underwent the initial operation in other institutions, having undergone a previous neck exploration. There were seven males and three females, ages ranging from 41-68 years. Six @entity1 had @entity1790 , four had both @entity1290 and @entity79 and two had @entity10189 . One of them was operated on as an emergency because of @entity2742 crisis with @entity460 levels of 15/16 mg%. Four @entity1 were asymptomatic and had @entity2741 detected by @entity11280 screening. The @entity460 level ranged from 11.5-16.2 mg%. The @entity3151 ranged from 1.6-2.8 mg% with a mean of 2.0 mg%. All ten @entity1 had plasma @entity461 determination by radioimmunoassay, the values ranged from 1.5-3 times normal. In seven of the ten cases, the mediastinal @entity3243 was localized within the thymus, the other three were adjacent to the great vessels, two to the aortic arch and one to the pulmonary artery-size ranging from 1.2-5.4 cm. Preoperative localization techniques: venous sampling in four cases; @entity1136 scanning in three cases. No preoperative localization techniques were used in the other three cases. There was no mortality nor other significant @entity260 .(ABSTRACT TRUNCATED AT 250 WORDS)
