The thyroid gland is a relatively uncommon site for a secondary malignancy; even less common is a case of malignant melanoma metastatic to the thyroid. We describe the case of a 68-year-old man who presented with a neck mass in the posterior triangle. Fine-needle aspiration biopsy (FNAB) identified the mass as a malignant melanoma. The patient had had no known primary skin melanoma. He underwen...

BACKGROUND Malignant follicular lesion is not differentiated from benign lesions cytologically. The objective of this study was to assess the rate and the risk of malignancy in thyroid nodules which were cytologically diagnosed as follicular neoplasm by fine-needle aspiration (FNA) cytology. METHODS All the patients who had undergone surgery with cytological diagnosis of follicular neoplasm f...

Objective: To find out the incidence of malignancy in patient with solitary thyroid

We present a case of a postmenopausal woman diagnosed with an ovarian mass containing thyroid follicles and foci of papillary thyroid carcinoma during pathological examination. This patient referred having had a metachronous thyroid malignancy 10 years before. The differential diagnosis between a thyroid malignancy arising from a struma ovarii and a metastatic ovarian tumor originating from thy...

Fine-needle aspiration (FNA) is commonly used as a preoperative assessment to diagnose thyroid cancer. However, misdiagnosis of malignancy by FNA is not rare, even if image examination suggests the possibility of thyroid cancer. In the present study, the clinicopathological factors of patients whose preoperative FNA examination had not led to a diagnosis of thyroid cancer were examined. In tota...

BACKGROUND Thyroid cancer is the most common endocrine gland malignancy and fine-needle aspiration biopsy is widely used for thyroid nodule evaluation. Repeated aspiration biopsies are needed due to plausible false-negative results. This study aimed to investigate the overall relationship between aspiration biopsy and thyroid cancer diagnosis, and to explore factors related to shorter diagnosti...

Multiple thyroid ectopia with a normally located thyroid gland is a very rare condition. We present a 34-year old Nigerian woman who had had anterior and left-sided lateral neck swellings for the past 15 years. She was clinically euthyroid and thyroid function test results were normal. Neck ultrasonography revealed multinodular goiter with extension to the left pre-auricular area. Fine Needle A...

Papillary thyroid carcinoma is the most common differentiated type of thyroid malignancy. It is largely a loco-regional disease with a high tendency to metastasize to regional cervical lymph nodes. Distant hematogenous metastases are very rare and primarily include lungs and bones. Distant bone metastases are present in approximately 1.7% of patients with differentiated thyroid malignancy. Ster...

OBJECTIVE To evaluate the accuracy and utility of intraoperative frozen section examination (iFSE) in patients with a preoperative fine-needle aspiration (FNA) cytology of "suspicious for malignancy" (SFM)-Bethesda V, after the adoption of the Bethesda System for Reporting Thyroid Cytopathology. STUDY DESIGN Case series with chart review. SETTING Tertiary medical center. SUBJECTS AND METH...
