Tumor-to-tumor metastasis is a rare occurrence. The most frequent metastatic donor is lung cancer, and the most frequent recipient is renal cell carcinoma. Here we present a patient in whom lung cancer served as a metastatic recipient and maxillary sinus adenoid cystic carcinoma acted as a metastatic donor. This patient has double primary lung cancer, which increased the complexity of this case.
肿瘤对肿瘤转移是一种罕见的现象。最常见的转移性供体是肺癌，最常见的受体是肾细胞癌。在这里，我们介绍了一位患者，其肺癌为转移性受体，而上颌窦腺样囊性癌为转移性供体。该患者患有双原发性肺癌，这增加了该病例的复杂性。
