OBJECTIVES: To identify the histopathological patterns of goiter in thyroidectomy specimens and their frequency in relation to age and gender of the patients.

METHODOLOGY: We present a retrospective data of 624 thyroidectomy specimens diagnosed over a period of six year (2007-2012) at the Department of Pathology, Holy Family Hospital, Rawalpindi, Pakistan.

RESULTS: A total of 624 consecutive thyroidectomy specimens were selected. Patient's age ranges from 11-89 years, 541 females and 83 males. There were 512 (82%) non-neoplastic lesions, which includes; 475 (76.1%) multi-nodular goiter (MNG), 16 (2.6%) Hashimoto thyroiditis, 11 (1.8%) colloid goiter, 4 (0.6%) toxic goiter, 2 (0.3%) chronic lymphocytic thyroiditis, 2 (0.3%) tuberculous thyroiditis and 2 (0.3%) miscellaneous. From 112 (18%) neoplastic lesions, 43 (6.9%) were adenomas (41 females and 2 males) and 69 (11.0%) were carcinomas (58 females and 11 males). Peak age for thyroid malignancy was 3rd to 4th decades. The histological subtypes of thyroid carcinomas includes, 35 (5.6%) follicular variant of papillary carcinoma (FVPC), 15 (2.5%) well-differentiated tumor of uncertain malignant potential (WDT-UMP), 6 (1%) medullary carcinomas, 6 (1%) papillary carcinomas, 3 (0.5%) anaplastic carcinomas, 2 (0.3%) follicular carcinomas and 2 (0.3%) other carcinomas. Twenty-nine (4.6%) neoplastic lesions were associated with MNG, includes; 2 (3.5%) follicular adenomas, 3 (0.5%) WDT-UMP and 4 (0.6%) FVPC.

CONCLUSIONS: MNG is common and FVPC is the common thyroid cancer seen in females. The overall frequency of thyroid cancer is 11%. Follicular adenoma and FVPC appears to be associated with long standing MNG of iodine deficiency....

: The present opinions on the therapy with L-thyroxine (L-T4) of non-toxic multinodular, as well as of non-toxic thyroid nodules are rather divergent. This treatment is based on the suppression of TSH secretion from the pituitary. There are no doubts that fine-needle aspiration biopsy (FNAB) performance is the first and--at the same time--the most significant diagnostic procedure in the case of thyroid structural lesions (nodules, goitre, thyroiditis). FNAB performance should--by all means--precede the beginning of L-T4 application for the treatment of non-toxic multinodular goitre or thyroid nodules. The simplicity, clearness and high efficacy, with comparable results in each case, are the core of good diagnostic algorithm. Unfortunately, not all diagnostic algorithms concerning thyroid nodules and multinodular goitre fulfil these important criteria....

: In the present review paper, the following problems have been brought up: 1) types of nontoxic goitre and applied classification, 2) physiological periods or states predisposing to non-toxic goitre development, 3) evaluation of excessive stimulation of the thyroid gland, 4) the treatment of iodine deficiency consequences (non-toxic diffuse vs. non-toxic nodular goitre), 5) autoimmunologically-induced non-toxic goitre, and 6) positive effects of iodine prophylaxis with respect to goitre prevalence. The management of non-toxic nodular goitre, as well as of thyroid nodules is a separate and very complex issue, and--at the same time--the subject of our next review paper, published in the same issue of NEL....
