Twenty-five cases of @entity704 with prominent cystic and hemorrhagic changes and areas of @entity39 and @entity1188 are presented. The @entity1 were 11 @entity1 and 14 @entity1 between the ages of 18 and 73 years (median 45.5 years). Clinically, nine @entity1 were @entity5 was discovered on routine chest radiograph. Sixteen @entity1 presented with symptoms of @entity662 and cough. All @entity1 underwent surgical resection of their @entity5 . Grossly, the @entity5 were described as well circumscribed and encapsulated, with the exception of two that showed infiltration of pleura and pericardium. The @entity5 measured from 4 to 13 cm in greatest dimension. On cut surface they showed prominent cystic areas and foci of @entity548 and @entity39 . Histologically, the @entity5 contained solid areas showing an admixture of round to oval epithelial cells devoid of atypia admixed with small lymphocytes in varying proportions. Cystic changes with areas of @entity39 , @entity1188 , and @entity548 were present in all cases and comprised extensive areas of the @entity5 . The areas of @entity1188 showed features of @entity63 @entity39 and were always intimately associated with vaso-occlusive and @entity715 phenomena and with cystic and hyperplastic changes of adjacent thymic epithelium. Clinical follow-up in 14 @entity1 showed that 11 were alive and well from 1 to 18 years after surgery (median follow-up 9 years). Three @entity1 died: one of complications during the immediate postoperative period, one because of @entity694 9 years after diagnosis of the @entity5 , and one because of @entity55 6 years later. The two @entity1 with invasive @entity5 were lost to follow-up. The present study appears to indicate that areas of @entity548 and @entity39 in well encapsulated, noninvasive @entity704 do not portend an adverse prognosis.
