RESUMO

Medullary carcinoma of the thyroid is an infrequent type of thyroid tumor. To retrospectively study all cases of MCT diagnosed at a regional hospital. The charts and pathological studies of eight patients with MCT among 75 with thyroidal cancer were reviewed. Solitary nodules were the presenting gign in seven patients and cachexia in one. Five patients were subjected to total thyroidectomy, five to cervical lymph node dissection and 4 to complementary radiotherapy. Pathological diagnoses was made with the surgical piece in 7 patients and the aspiration cytology in 1. Five of the 8 patients are alive after 50 months of follow up as a mean, 1 patient with bone metastasis. The small sample size precludes conclusions on the prognosis and treatment of the disease
