胸腺瘤是胸腺最常见的肿瘤,WHO组织学分类对胸腺瘤的诊断有很大的帮助。然而,在活检标本中仅仅根据形态学区分胸腺瘤与非肿瘤性胸腺组织或胸腺增生是很困难的。作者研究了凋亡蛋白X连锁抑制因子(XIAP)和p63在11例胸腺增生和12例胸腺瘤中的表达。12例胸腺瘤中有包膜者3例(B2型1
Thymoma is the thymus’s most common tumor. WHO histological classification is of great help in the diagnosis of thymoma. However, it is difficult to differentiate thymoma from non-neoplastic thymus tissue or thymus hyperplasia only in morphology based on the morphology of biopsy specimens. The authors studied the expression of the apoptotic protein X-linked inhibitor (XIAP) and p63 in 11 cases of thymus hyperplasia and 12 cases of thymoma. Thymoma in 12 cases were enveloped in 3 cases (B2 type 1
