Ultrastructure of a primary fibrosarcoma of the human thyroid gland.

A primary fibrosarcoma of the thyroid occurring in a patient with a nodular goiter is described. Light microscopy showed interwoven bundles of spindle cells admixed with plump ovoid cells, and foci of multinucleated giant cells. Remnants of distorted thyroid follicles were found only at the periphery of the tumor. "Transitional" epithelial elements were not discernible but the tumor resembled an anaplastic giant cell carcinoma. Multiple blocks studied by electron microscopy, however, revealed that the tumor cells, including the giant cells, have the ultrastructure features of a fibroblast.

Pulmonary blastoma. Report of two cases in children.

Pulmonary blastoma is a rare tumor of the lung. Although it has been stated that this is predominantly a tumor of adults, a review of the 42 cases published to date reveals that it is a disease which occurs with some frequency in children. The tumor is relatively benign compared to pulmonary carcinosarcoma. Of the eight cases previously described in children, three are known to have survived and to be free of disease 10 months, 3 and 8 years after surgical resection. We report two additional cases of pulmonary blastoma in children followed for 34 and 26 months without any evidence of recurrence or metastases.
