title: De novo calcification in lymph node metastasis.
abstract: Calcification in malignant lymphoma or in lymph node metastases from a malignant tumor are most often encountered after radiotherapy or chemotherapy. De novo calcifications in malignant lymphoma however, are very rare. As far as we know, de novo calcification in retroperitoneal lymph node metastases from carcinoma have not been described before. A case is presented and the literature is reviewed.
