BACKGROUND: The State of Goiás has left the position of an endemic goiter region in 1995. Our objective is to study the correlation between histological diagnosis of thyroid diseases (endemic goiter, thyroiditis and cancer) and results of epidemiological enquiries. METHODS: Retrospective analysis of 1399 patient files, who underwent thyroid surgery from 1993 to 2003 at the Santa Casa de Misericórdia de Goiânia. RESULTS: We detected 1610 histological diagnosis: follicular adenoma in 155 (9.63%), others adenomas in 29 (1.80%), adenomatous goiter in 87 (5.40%), colloid goiter in 981 (60.9%), follicular carcinoma in 36 (2.24%), anaplastic carcinoma in 3 (0.19%), papillary carcinoma in 93 (5.78%), cysts in 9 (0.56%), toxic diffuse goiter in 75 (4.66%), others thyroiditis in 12 (0.75%), others malignancies in 6 (0.38%) and lymphocytic thyroiditis in 124 (7.71%). CONCLUSIONS: There was a high prevalence of lymphocytic thyroiditis and papillary carcinoma, the same as usually observed in non endemic regions.
