Rare and unusual features of malignant tumors are spontaneous tumor regression and tumor maturation. An even more unusual pattern is the "reactive" mass formation produced by fibrous tissue proliferation and inflammation following radiotherapy and simulating tumor recurrence, like in the following case of pulmonary carcinoid. Radiological and pathological documentations are presented and discussed.
恶性肿瘤罕见且不寻常的特征是肿瘤自发消退和肿瘤成熟。一种更为不寻常的模式是放疗后由纤维组织增生和炎症产生的“反应性”肿块形成，类似肿瘤复发，如下例肺类癌所示。本文展示并讨论了影像学和病理学资料。
