Soft tissue implantation of thyroid tissue is a very rare event. Needle tract implantation of thyroid carcinoma after fine-needle aspiration (FNA) biopsy has been occasionally reported, but implantation of benign thyroid tumor tissue is extremely rare. Rupture of thyroid tissues during surgery or trauma may cause the thyroid tissue to be implanted and result in multiple palpable nodules in soft tissue of the neck. Several reports have shown the possibility of implantation of normal or hyperplastic thyroid tissues in soft tissue. We herein report a case of implantation of adenomatous hyperplastic tissue in the neck along the trochar and previous operation site after endoscopic thyroid surgery, which was successfully treated by complete excision.

Medullary thyroid carcinoma constitutes about 5-10% of all thyroid malignancies, but rare in children. It has frequent association with multiple endocrine neoplasia(MEN) and frequent familial occurrence. They are derived from parafollicular cells of thyroid glands and produce calcitonin. They are capable of local invasion, spread to regional lymph nodes, or distant metastases. Histopathologically, the lesions are characterized by sheets of non-follicular cells surrounded by deposits of hyaline amyloid. Aggressive surgical intervention is recommended due to the propensity of medullary thyroid carcinoma for local microvascular invasion, late recurrence and metastasis. A total thyroidectomy is generally recommended because of the high incidence of bilaterality. Recently, authors experienced a case of medullary carcinoma in child. We report this case with review of the literatures.

We report a 37 year-old-female patient with papillary thyroid cancer treated by surgery who demonstrated residual thyroid and bilateral breast uptake on a diagnostic I-131 whole body scan. She had an extrathyroidal extension needing I-131 ablative therapy. Her galactorrhea was investigated and treated with low doses of bromocriptine prior to I-131 therapy. Her galactorrhea was due to the decreased secretion of PIF induced by empty sella.

The activation of adenylate cyclase of human thyrocytes in primary cell culture and the release of c-AMP into the medium are used to detect b-TSH and TSAb in sera of patients with autoimmune thyroid disease. Sera of patients are used directly as a part of cell culture without immunoglobulin precipitation. In the above TSI bioassay, TSAb pooled serum show c-AMP concentration between that of 1mU/ml and 10 mU/ml b-TSH but normal control pooled serum doesn't show any detectable c-AMP response. Ninety fiye percent of untreated Graves' patients shows TSAb activity above normal range, 20% of Hashimoto's and 36% of euthyroid Graves' patients show detectable TSAb activity.

A 62-year-old female patient had goiter for twenty years. She visited out-patient clinic with a hoarse voice and intermittent breathing difficulties. About protruding 15cm sized mass located the anterior neck and right vocal cord paralysis was observed. Preoperative CT scan was strongly suspected of thyroid gland cancer and cervical lymph node metastasis. Therefore, fine needle aspiration test was performed and surgical treatment was planned with the histopathologic results (papillary thyroid carcinoma). Surgery was performed with total thyroidectomy, bilateral cervical lymph node dissection, and right selective nodal lymph node dissection (level II-V). During operation right thyroid seemed to be adherent to surrounding tissue and the blood vessels were extremely engorged. There was hypotensive crisis because of intraoperative excessive bleeding. However it was managed by repetitive transfusion. The operation was completed without abnormalities. She underwent 4 times of bleeding control operation due to postoperative bleeding. After complications were improved, we are currently undergoing out-patient follow up without morbidity.

An intrathyroid thyroglossal duct cyst (TGDC) presented as an anterior neck mass in a 62-year-old male without history of prior thyroid disease or infection. This cyst was clinically indistinguishable from a thyroid nodule. In addition to that, fine needle aspiration cytology revealed normal-looking squamous cells. Diagnosis, work-up, management approach, and treatment of intrathyroid TGDC are discussed as well as distinguishing features between intrathyrod TGDC with tract and without tract. This is the very rare case of intrathyroid TGDC in Korean population and the possibility of intrathyroid TGDC should remain in the differential diagnosis of thyroid nodule.

Evaluating the patient's voice before thyroidectomy is useful for the purpose of identifying patients with vocal cord paralysis without symptoms, identifying other patient's voice abnormalities, and whether it is related to voice disorders that may occur after surgery. Also voice evaluation after thyroid surgery is helpful in diagnosis, treatment, and rehabilitation and follow-up of voice disorders that occur without clear nerve damage after thyroidectomy. And it is helpful for rapid recovery through active early rehabilitation treatment for patients who complain of speech impairment without paralysis. In particular, neck exercise can improve the adhesion of the surgical site and increase the range of motion of the neck as well as improve subjective neck discomfort. In addition, hearing, voice and breathing functions should be improved, and voice hygiene education and counseling should be provided. Vocal cord injection is the first treatment option for unilateral vocal cord palsy. By establishing a protocol for voice disorders before and after thyroid surgery and providing appropriate treatment, the quality of life of patients can be improved.

Common carotid artery (CCA) rupture during parathyroid cancer surgery is extremely rare and is generally life-threatening. We present a case of successful management of a ruptured CCA following the emergency placement of stent-graft in a 59-year-old male diagnosed with recurrent parathyroid cancer. During recurrent parathyroid cancer surgery, his right CCA ruptured unexpectedly, and his vital signs deteriorated rapidly despite surgical management. After stent replacement, his unstable vital signs improved and, thereafter, he was discharged without any complications.

Primary thyroid lymphoma is rare and accounts for less than 5% of all thyroid malignancy. The clinical presentation includes a rapidly enlarging neck mass, associated with dysphagia, dyspnea or hoarseness. The most common histologic type is diffuse large B cell non-Hodgkin's lymphoma. Papillary thyroid carcinoma is the most common type of thyroid malignancy. Co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma is very rare. Recently, we experienced a case with co-occurrence of papillary thyroid carcinoma and primary thyroid lymphoma in a 79-year-old woman, who had tuberculous lymphadenitis presented as lateral neck mass. We present this case with a review of the literature.
