Background Thyroid carcinoma complicated by hemiagenesis is very rare, and previous reports have not described this cancer on the side of the absent lobe. Methods and Results We report the case of a 64-year-old woman in whom left thyroid hemiagenesis was discovered incidentally during investigations of abnormal sensation during swallowing. A tumorous 1.4 cm lesion was also found on the side o...

This study was done retrospectively to analyze the ultrasonographic (US) findings in thyroid scintigraphic hot areas (HA). Three-thousand, eight-hundred and thirty-nine consecutive patients who underwent 99mTc-pertechnetate (n = 3435) or 123I (n = 457) scintigraphy were analyzed. HA were regarded as present when the tracer concentration was greater than the remaining thyroid tissue, or when hem...

Peripheral nerve regeneration is a unique process in which cellular rather than tissue response is involved. Depending on the extent and proximity of the lesion and the age and type of the neuronal soma, the cell body may either initiate a reparative response or may die. Microsurgical intervention may alter the prognosis after a peripheral nerve injury but to a certain extent. By altering the b...

Parathyroid cyst (PC) is a very rare condition. A case of intrathyroidal PC is being reported here in a 53-year-old woman who presented to the endocrine clinic with slowly progressive painless left anterior neck swelling for 1 year with no symptoms of thyroid or parathyroid dysfunction and no compressive symptoms. Ultrasound of the thyroid showed a well-defined cystic lesion measuring 4.7 × 3.6...

The activation of RET protooncogene, through chromosomal translocation, is unique to papillary thyroid carcinomas. Rearrangement of the RET kinase domain to 3 partner genes has been described, of which the RET/PTC1 is the most common. To investigate the frequency of RET rearrangement in Chinese papillary thyroid carcinomas, we have performed RT-PCR to amplify specific RET/PTC transcripts. Among...

BACKGROUND Renal cell carcinoma is an interesting tumor due to its unpredictable behavior. Common metastatic sites of renal cell carcinoma are the lungs, lymph nodes, bones and liver. Concurrent thyroid metastasis of clear cell carcinoma is uncommon but it can appear as a rapidly growing cervical, painless nodular mass. CASE REPORT We report a case of a 56-year-old male patient with clear cel...

Most of thyroid lymphomas are B-lineage, and T-cell lymphomas are rare. Here, we report a case of primary thyroid T-cell lymphoma associated with Hashimoto's thyroiditis. A 48-yr-old woman presented with incidentally found neck mass. Histologically, the resected right lobe of the thyroid was replaced by monomorphic small atypical lymphoid cells with lymphoepithelial lesion-like change, most of ...

We compared the diagnostic sensitivities of 123I and 131I whole-body imaging in differentiated thyroid cancer. Methods: Twelve thyroidectomized patients (3 previously treated with 131I) were studied. After a period of thyroid hormone withdrawal, whole-body imaging was performed approximately 24 and 72–96 h after administration of 74 –185 MBq (2–5 mCi) 123I and 111–185 MBq (3–5 mCi) 131I, respec...

BACKGROUND Papillary thyroid carcinoma is rarely associated with metastatic disease. The most common sites of metastasis are the lungs and bones, while only few cases of ovarian metastasis are described in literature. CASE We report the case of a 51 years old woman, treated 9 years before for papillary thyroid carcinoma, presenting to our Institute with a pelvic ovarian mass revealed by ultra...

Objective. Tuberculosis of the thyroid gland is a very rare disease. The incidence of extrapulmonary tuberculosis has been showing a progressive increase in the recent years. We present three cases of primary thyroid tuberculosis. Methods. Two cases were diagnosed on the basis of fine-needle aspiration cytology (FNAC), as they presented with thyroid nodule. The third case was diagnosed on histo...
