Thyroid cancer (TC) is considered the most common malignancy of the endocrine system. Papillary Thyroid Microcarcinoma (PTMC) is defined as tumors of less than or equal to 10mm in diameter, it could be non-incidental or incidental.
To evaluate the prevalence rate of thyroid papillary microcarcinoma, and to correlate the prevalence rate with different parameters including: age, gender, clinical diagnosis and type of surgery.
PATIENTS AND METHODS:
The present study, which is a retrospective study, was conducted on 489 cases of thyroidectomy specimens; the study was conducted at the Teaching laboratories of Medical City over a period of one year from February 2015 to Feb. 2016. The incidence of thyroid papillary microcarcinoma was correlated with different parameters including age, sex, clinical presentation, and type of surgery.
In this study , cases were divided into: 53(10.83%) cases male, and 436 (89.171%) cases females, with age range 15-68 years and age mean 41.5 years ,regarding histopathological diagnosis ,cases were analyzed as followed: Nodular hyperplasia 354(72.41%) cases. Autoimmune thyroiditis 34(7.0%) cases, thyroid adenoma 28(5.7%) cases, follicular tumors 2 (0.4%) cases, papillary microcarcinoma 28(5.7%) cases, papillary carcinoma 16(3.3%) cases, follicular carcinoma 3(0.6%) cases, medullary carcinoma 1(0.2%) cases, hyperplastic nodule 6(1.2%) cases, toxic goiter 10(2.0%) cases, infections thyroiditis 1(0.2%) case, papillary carcinoma with lymph node involvement 4(0.8%) cases, thyroglossal cyst 1(0.2%) case, parathyroid adenoma 1(0.2%) case. Eight cases of PTMC(3.3%) were below 40 years of age. 20(8.1%) cases were above 40 years. There was a statistical correlation between age and prevalence of TPMC.
The possibility of thyroid microcarcinoma should always be kept in mind while diagnosing a benign thyroid disease. There was a significant statistical correlation between age and prevalence of thyroid papillary microcarcinoma.
