摘要

摘要: 腺泡细胞癌（ACC）是一种涎腺上皮源性恶性肿瘤，主要发生于涎腺，而肺内原发腺泡细胞癌极其罕见。由于其临床发病率非常低，相关文献报道少，临床医生对其认识不足，容易误诊而延误病人治疗。故本文报道了一例经手术病理证实的原发性肺腺泡细胞癌，并结合相关文献，总结本病的CT影像表现以及MSCT在本病诊疗中的价值，以提高对该病的认识和影像诊断水平。

Abstract: Acinic cell carcinoma (ACC) is a malignant epithelial salivary gland neoplasm that most frequently occurs in the salivary glands. However, primary ACC of the lung is extremely rare. Due to its low incidence and the lack of related literature, clinicians lack relevant knowledge. It is prone to misdiagnosis, which delays the treatment of patients. Thus, we report a case of primary ACC of the lung confirmed via surgery and pathology, together with a review of relevant literature, in order to summarize the CT imaging manifestations and the value of CT in the diagnosis and treatment of this disease. The aim of this case report was to improve the understanding of primary ACC of the lung and to improve the diagnostic abilities.

图 1 胸部MSCT表现

（a）～（d）胸部CT平扫肺窗，左肺上叶舌段结节，结节边缘可见“空气新月征”（粗箭），结节近侧、远侧支气管轻度扩张（细箭）；（e）矢状位CT重建：远侧扩张支气管稍扩张，腔内少许异常密度充填。（f）～（h）纵隔窗，结节呈浅分叶改变，结节内密度不均匀，伴有多发不规则条、片状钙化；（g）和（h）胸部CT增强动脉期结节显著强化，CT值约133 HU；静脉期病灶强化稍减低，CT值约94 HU；（I）MPR重建：病灶供血动脉显示；（J）MIP：病灶由左肺上叶舌段动脉分支供血。

（a）（HE×10）瘤组织与周围肺组织边界较清楚，瘤组织呈片巢状分布，部分区域呈腺样排列，腺腔内见红染无结构分泌样物，瘤细胞呈类圆形、多边形、柱状，部分胞浆空亮，间质较多浆细胞浸润。（b）（HE×20）瘤组织呈片巢状分布，瘤细胞轻度异型，部分胞浆空亮，间质见浆细胞浸润。（c）（HE×20）瘤组织呈片巢状分布，部分区域呈腺样排列，腺腔内见红染无结构分泌样物，瘤细胞呈类圆形、多边形、柱状，部分胞浆空亮。（d）（HE×20）瘤组织浸润支气管粘膜，间质见钙化。（e）免疫组化：CK（＋）。（f）免疫组化：CK7（＋）。
