| pubmed-article:376091 | pubmed:abstractText | A strumal carcinoid of the ovary was studied by light and electron microscopy. Thyroglobulin was demonstrated within the strumal element by immunofluorescence, thus establishing the identity of the thyroid tissue. The carcinoid fulfilled the light and electron microscopic criteria for a mixed insular and trabecular example of this tumor. Intermediate zones between the two tissue elements showed mixed characteristics. No amyloid was found. Immunoreactive calcitonin was demonstrated in the tumor, suggesting the presence of C-cells or medullary carcinoma of the thyroid. | lld:pubmed |
