Alveolar adenoma is a rare pulmonary neoplasm. This report describes a case of alveolar adenoma of the lung in a 61-year-old woman. A chest X-ray demonstrated a solitary round pulmonary nodule. After six years of observation, this lesion had increased in size. Thoracoscopic left upper segmentectomy was performed on account of a possible low-grade malignant tumor. Histologically, the neoplastic epithelial cells, which had the appearance of proliferative type II pneumocytes, revealed no evidence of malignancy. These findings indicated that the tumor is alveolar adenoma of the lung. The course of disease remains uneventful, one year after the resection.
肺泡腺瘤是一种罕见的肺肿瘤。本报告描述了一名61岁女性的肺肺泡腺瘤病例。胸部X线显示一个孤立的圆形肺结节。经过六年观察，该病变大小增大。鉴于可能为低级别恶性肿瘤，行胸腔镜左上叶切除术。组织学上，肿瘤上皮细胞呈增生性II型肺细胞外观，未发现恶性证据。这些发现表明该肿瘤为肺肺泡腺瘤。切除术后一年，病情平稳。
