title: [Thyroid neoplasm of mid follicular-medullary type; an uncommon, particular and aggressive form: report of 3 cases].
abstract: Mixed medullary and follicular carcinoma of the thyroid shares secretory and immunohistochemical features of both follicular and parafollicular thyroidal cells. We report three women, aged 34, 63 and 61 old with this type of tumor. Its diagnosis must be bore in mind in patients with thyroidal tumors and a histological appearance of a medullary or undifferentiated carcinoma. An early diagnosis of a mixed medullary and follicular carcinoma of the thyroid is important, considering its special treatment and negative prognosis.
