1肺类癌的病理表现。A:肺典型和不典型类癌中最常见的器官样结构生长方式。肿瘤细胞较一致,胞浆中等量,嗜酸性,核呈细颗粒状(HE, ×40);B:肺非典型类癌可出现灶状坏死(HE, ×40);C:免疫组化显示类癌嗜铬素A阳性(×40);D:本例典型类癌Ki-67指数约为2%(×40);E:本例不典型类癌Ki-67指数约为10%(×40);F:本例类癌组织学形态类似硬化性血管瘤(HE, ×40)。
The pathological pattern of lung carcinoid. A: An organoid growth pattern is the most common histologic pattern in both typical and atypical carcinoid. Tumor cells have uniform cytologic features with a moderate amount of eosinophilic cytoplasm. Nuclear features usually consist of finely granular chromatin; B: The necrosis usually consists of small punctate foci in atypical carcinoid; C: Imunohistochemistry shows chromogranin A is positive in carcinoid; D: The Ki-67 index in carcinoid is lower; E: The Ki-67 index in atyical carcinoid is higher; F: The morphology in carcinoid is similar as sclerosing hemangioma.
