Introduction: Thyroid cancer is the most common endocrine neoplasia, being its papirally version the most frequent. (90% of all differentiated thyroid neoplasms). It is usually multifocal and metastasizes normally to regional lymph nodes.

Objectives: To describe the prevalence of thyroid cancer and its histopathological variants in the different regions of the province of Malaga.

Material and methods: We performed a retrospective descriptive study. We collected the thyroid cancer diagnoses in the databases of pathological Anatomy of the different hospital centers of the province between 2010 and 2015.

Results: 545 cases were collected, it is more frequent in women (79.63%) than in men (20.37%); the average age at diagnosis was 50±15 years. Analyzing in different areas: 30.1% East Málaga; 12.5% West Málaga, 30.1% Costa del Sol, 1.3% Guadalhorce Valley, 1.5% Serranía de Ronda/ Sierra de las Nieves, 7.3% Axarquía, 3.1% Antequera, 2.4%, 2.7% Melilla. The most frequent histological variant was papillary (69.72%) and in the different areas: East Málaga: 76.22% papillary, 9.15% follicular, 6.71% micropapillary, 3.65% medullary, 1.83% anaplastic, 1.22% Hurtle cel, 1.22% oncocytic. West Málaga; 63.25% were papillary, 11.76% were follicular, 13.23% were micropapillary, 4.41% were medullary, 4.41% were oncocitic, 2.94% were Hurtle; Or anaplastic. Axarquia 73.17% papillary, 4.88% follicular, 9.76% micropapillary, 9.76% medullary, 2.44% anaplasic. Gualdalhorce Valley 77.59% were papillary, 6.89% follicular, 10.34% micropapillary, 1.72% medullary, 3.45% no data. Antequera, 64.71% papillary; 17.65% follicular, 11.76% micropapillary, 5.88% medullary. Serranía Ronda/Sierra Nevis: 75% papillary, 12.5% follicular, 12.5% micropapillary. In Costa del Sol 59.76% papillary, 12.20% follicular, 8.54% micropapillary, 1.22% medullary, 0.61% anaplastic, 4.27% Hurtle cel, 13.41% no data. Melilla: 80.02% papillary, 6.66% follicular, 6.66% micropapillary, 6.66% anaplasic In other provinces: 84.62% papillary, 7.14% follicular, 7.14% medullary. Tumor tissue was noticed to surpass the resection capsule in 19.08% (without data 11.93%). In 33%, no ganglia were removed, 21.6% of affected nodes and distant metastases>1%.

Conclusions: The prevalence of thyroids cancer in our population was similar to those described in Spain. In the analysis of different types, papilar was the most frequent, followed by follicular and micropapillaries. The overall prognosis is good.
