Carcinoid Tumor of the Thymus- A Case Report and Review of the Literature

胸腺類癌（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，臨床表現也經常合併內分泌異常。茲報告一位45歲男性病患主訴前胸痛半年而到院求診，臨床並無內分泌異常表現。影像學發現是一個8.7×3.9 公分的前縱膈腔腫瘤，切片證實為胸線類癌。經外科廣泛手術切除及輔助性化學治療後於門診繼續治療中。由於胸腺類癌具有局部侵犯及遠處轉移之傾向，當胸部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。

Carcinoid tumors of the thymus are rare, and comprise a wide spectrum of lesions ranging from well-differentiated to poorly-differentiated neoplasms.Clinically, they are commonly associated with endocrine abnormalities. We report a 45-year-old man presenting with anterior chest pain and tightness lasting for half a year before admission. Moreover, no endocrine abnormalities were noted clinically. The image finding disclosed a mass with an irregular contour, about 8.7 x 3.9 cm, in the anterior mediastinum. Ultrasound-guided biopsy demonstrated a thymic carcinoid tumor. The patient underwent radical surgical resection with adjuvant chemotherapy, and followed up at the outpatient clinic. Thymic carcinoid tumors have a tendency toward local invasion and distant metastasis, and should be included in the differential diagnosis of anterior mediastinal tumors.
