Abstract

We report two pathologically proven pure ground-glass nodules found in two patients with malignant melanoma. In one patient, the nodule showed no growth over 2 months and was found to be bronchioloalveolar carcinoma, whereas in the other patient, a nodule grew rapidly over 3 months and was histologically confirmed to be metastatic melanoma.
