Progressively increasing density of the solid center of a ground-glass nodule in a solitary pulmonary capillary hemangioma: A case report.

abstract：:Malignant transformation of ovarian mature cystic teratomas is reported to occur in about 1% of cases. The most common malignant evolution is that of squamous cell carcinoma and one of the least common is that of small cell carcinoma. We report a case of distant metastasis from a small cell carcinoma arising in a matu...
