Background and Purpose: This study was intended to record the number of endocrine cancer in four provinces of Iran.
Methods and Materials: Patients in each province were classified according to their age, gender, sex, and tumor characteristics (site, morphology and behavior). The obtained data were coded according to ICD-O. High- risk age was calculated for each province and the results presented as incidence rates by sex, age, age- specific rates and ASR per 100,000 person – years using standard statistical methods to the world population.
Results: Out of 319 cases of primary endocrine cancers found and recorded, 313 cases were thyroid carcinoma and 6 cases were adrensal cancers. In thyroid carcinoma group, the share of Papillary, follicular, medullary and anaplastic carcinomas accounted for 82.7%, 8.6%, 7.0% and 1.6% respectively. Also, the ASR of thyroid carcinoma for total, male and female cases were 1.289, 0.627 and 1.59 respectively. The highest incidence rate of the thyroid carcinoma was found in Kerman with the ASR of 1.643 for both genders and the lowest rate in Golestan with the ASR of 0.735. Mean age of patients was 43.9 years (SD=15.90) and their age ranged from 3 to 8 years. This figure for males was 45.21 (± 17.13) and for females 43.49 (±15.51) (P= 0.41). Also, the female - male ratio was 3.1 to 1. In adrenal cases (n=6), 4 cases (66.7%) had neuroblastoma and 2 cases were pheochromocytoma (33.3%). The mean diagnosis age was 16.17 (± 7.05) years for the whole population of cases; 13.00 (±3.46) years for males and 19.33 (±9.07) for females (P=0.32)
Conclusion: Iran was considered as an endemic iodine-deficient region until fairly recently. However, iodinization of salt started 12 years ago and since then, this increase has caused an increase in the incidence of papillary cancer, compared to other thyroid carcinomas; its frequency and distribution closely correspond to the observed profile in areas with high iodine consumption.

Background and Purpose: Spinal cord compression due to metastasis, as the initial presentation of follicular thyroid carcinoma, is quite uncommon. In this article, we report one case of well-differentiated thyroid carcinoma which has led to the compression of the spinal cord.
The patient: The case we report here is a man of 53 years old, with increasing neck pain, paraplegia and urinary incontinence. Magnetic resonance imaging of the neck revealed a mass which had destructed C5 with extension to C6.
Conclusion: Histopathology examination demonstrated the metastasis of a well-differentiated follicular carcinoma of thyroid. Therefore, the metastatic lesion of the thyroid carcinoma should be considered in any case of spinal cord compression.
