下列哪项不是肿瘤？（）
A.血管瘤
B.蕈样霉菌病
C.尤文肉瘤
D.室壁瘤
E.葡萄胎
参考答案：D
解析：蕈样霉菌病属于恶性淋巴瘤的一种，典型症状为皮肤呈蘑菇状病损。Ewing瘤属于一类未分化的小圆细胞肿瘤，目前基础研究的进展证实其为外周原始神经外胚层瘤，恶性程度高，预后差。血管瘤多为先天性良性肿瘤或血管畸形，多见于婴儿出生时或出生后不久，它起源于残余的胚胎成血管细胞。葡萄胎是妊娠时胎盘绒毛上的滋养细胞不正常的分裂和增殖，使胎盘绒毛形成大小不等的水泡，形似葡萄，也称水泡状胎，有侵袭性葡萄胎和恶性葡萄胎。而室壁瘤是由于心肌坏死以后形成瘢痕，瘢痕组织薄弱，在心内压力作用下容易鼓出，形成室壁瘤，不属于肿瘤。
The situation seemed hopeless. From the first day he entered my junior-high classroom, Willard P. Franklin lived in his own , shutting out his classmates and me, his teacher. I tried to build a relationship with him but he showed no interest. Even a “Good Morning Willar” received only a grunt(咕哝) that couldn’t be . Willard was a loner(孤独的人) who seemed to have no hope or need to break silence. Shortly after the Thanksgiving holiday, we received the news of the annual(每年的) Christmas collection of money for the less people in our school district. “Christmas is a season of ,” I told my students. “There are a few students in the school who might not have a happy holiday season. donating our Christmas collection, you will help buy food, clothing and toys for these needy people. We start the collection tomorrow.” When I called for the donations the next day, I discovered that everyone had forgotten, except Willard P. Franklin. The boy dug deep into his pants pockets he walked up to my desk. Carefully, he two coins into the small box. “I don’t need milk for lunch,” he said . For a moment, just a moment, he smiled . Then he turned and walked back to his desk. That night, after school, I took our to the school principal. I couldn’t sharing the incident(事件) that had taken place. “I may be wrong, but I believe Willard might be getting ready to become a part of the world around him,” I told the principal. “Yes, I believe it is for him to get out of his own world,” he nodded. “And I think we can do something to have him a bit of his world with us. I just received a of the poor families in our school who most need help through the Christmas collection. Here, take a look at it.” As I read, I discovered Willard P. Franklin and his family were the top names on the list.
