中文摘要 | 胸腺類癌(即原發性神經內分泌胸腺瘤)為一種罕見腫瘤,其細胞分化良惡之間涵蓋甚廣。茲報導一例前縱膈腔腫瘤,證實為非典型胸類腺癌,並具有「中等程度分化的非典型神經內分泌癌」之組織病理性質。同時也討論該例之其臨床表徵、影像學發現與病理學診斷。本例在影像學上表現大區域壞死,適可印證組織病理分化等級,較為特殊。由於胸腺類癌具有局部侵犯及遠處轉移之傾向,當X光或電腦斷層(CT)片辨識出前縱膈腔腫瘤時,必須將其納入鑑別診斷。並期待大區域壞死之影像特徵能預測此類腫瘤的組織病理分級。 |
英文摘要 | Carcinoid tumor of the thymus is a rare neo-plasm. It comprises a wide spectrum of lesions ranging from well-differentiated to poorly-differen-tiated neoplasms. We report a case of anterior mediastinal mass, which is proven to be an atypical thymic carcinoid tumor with a histopathological nature of intermediate-grade moderately-differenti-ated neuroendocrine carcinoma. We also present the patient’s clinical manifestations, imaging find-ings and pathological diagnosis. This tumor reveals large area of necrosis in imaging finding, which cor-responds with its histopathological differentiation and classification. Since the thymic carcinoid had a tendency of local invasion and distant metastasis, it should be included in the differential diagnosis of anterior mediastinal tumor identified on chest X-ray or CT films. The imaging finding of large necrotic area can be predictable in its histopathological grading. |
