A 29-year-old woman with an unusual form of pulmonary metastasis from epithelioid sarcoma of the right forearm is presented. Since she manifested left pneumothorax due to metastatic pulmonary cyst 7 years ago, the only metastatic manifestation has been the presence of bilateral multiple thin-walled pulmonary cysts; no other types of pulmonary lesions, such as nodules, cavitary lesions with thick or irregular walls, or extrapulmonary metastases, have been found. Pathologic studies revealed metastatic proliferation of sarcoma cells in the wall of the pulmonary cysts and infiltration of malignant cells inside the microscopic cavitary metastases surrounded by normal lung parenchyma.
本文报告了一名29岁女性，其患有右前臂上皮样肉瘤的一种不寻常形式的肺转移。7年前，她因转移性肺囊肿出现左侧气胸，此后唯一的转移表现一直是双侧多发薄壁肺囊肿；未发现其他类型的肺部病变，如结节、壁厚或不规则的空洞性病变或肺外转移。病理研究显示，肺囊肿壁上有肉瘤细胞的转移性增殖，在被正常肺实质包围的微小空洞性转移灶内有恶性细胞浸润。
