Thymic neoplasms are a common cause of an anterior mediastinal mass and may be benign or malignant. Thymic cysts are congenital or acquired and may be associated with a thymic malignancy. True thymic hyperplasia and thymic lymphoid hyperplasia may enlarge the thymus and simulate a neoplasm. Thymoma and thymic carcinoma are epithelial malignancies with distinct clinicopathologic features. Thymic carcinoid is a rare aggressive neuroendocrine malignancy associated with multiple endocrine neoplasia 1. Thymolipoma is a benign neoplasm. Hodgkin and non-Hodgkin lymphoma may primarily or secondarily involve the thymus. Primary mediastinal germ cell tumors may arise primarily within the thymus and include mature teratoma, seminoma, and non-seminomatous malignant germ cell tumors.
胸腺肿瘤是前纵隔肿物的常见病因,可为良性或恶性。胸腺囊肿可为先天性或后天性,可能与胸腺恶性肿瘤相关。真性胸腺增生和胸腺淋巴样增生可使胸腺增大并类似肿瘤。胸腺瘤和胸腺癌是具有独特临床病理特征的上皮性恶性肿瘤。胸腺类癌是一种罕见的侵袭性神经内分泌恶性肿瘤,与多发性内分泌肿瘤1型相关。胸腺脂肪瘤是一种良性肿瘤。霍奇金淋巴瘤和非霍奇金淋巴瘤可原发或继发累及胸腺。原发性纵隔生殖细胞肿瘤可主要起源于胸腺内,包括成熟畸胎瘤、精原细胞瘤和非精原细胞性恶性生殖细胞肿瘤。
