A Case of Tracheal Adenoid Cystic Carcinoma Presenting with Diffuse Goiter / 대한내분비학회지

A goiter is among the most common presenting symptoms of patients with thyroid diseases and is usually caused by intrinsic thyroid problems. While direct invasion of the trachea by aggressive thyroid tumors is a well-known phenomenon, the reverse situation, that is, a primary tracheal neoplasm invading by direct extension into the thyroid gland, presenting with a goiter is very rare. Here, a case of a tracheal adenoid cystic carcinoma(ACC), presenting with a diffuse goiter, is reported. A 47-year-old woman presented with slowly growing anterior neck swelling. A physical examination showed a diffuse firm goiter. The patient was euthyroiditic, and serum negative for thyroid autoantibodies. Thyroid ultrasonography and neck CT revealed a doughnut-shaped mass, encircling the trachea and displacing the thyroid anteriorly. Ultrasonography-guided fine needle aspiration(FNA) was compatible with an ACC, and a subsequent surgical resection confirmed the diagnosis. Although the occurrence of a tracheal ACC invading the thyroid is rare, this case highlights the need to be aware of unusual lesions arising in the region of the thyroid. This knowledge will help in making the correct cytological diagnosis when these lesions are sampled by FNA

A case of gastric diverticulum simulating an adrenal incidentaloma / 대한내과학회지

Adrenal incidentalomas are increasingly diagnosed with the widespread escalation in the use of high-tech imaging modalities and marked improvements in image resolution. However, several conditions can simulate a left adrenal mass as a result of the proximity of the left adrenal gland to the gastric fundus, spleen, first loops of the jejunum, and tail of the pancreas. We report a patient with a diverticulum of the gastric cardia that simulated a left adrenal mass. To the best of our knowledge, this is the first report of such a case in Korean literature. Typical radiologic findings and clinical course are presented with reviews of the literature.

A case of acromegaly with mixed papillary-follicular thyroid carcinoma / 대한내과학회지

Patients with acromegaly have high incidence of benign or malignant neoplasia than general population and many investigators suggest the stimulatory effect of GH and IGF-1 on mesenchymal cells. Both normal thyroid tissue and thyroid cancer cells express IGF-1 receptor and thyroid cancer cells have more than 3 times. We present a case of acromegaly in patient with mixed papillary-follicular thyroid carcinoma, suggesting the possible carcinogenic role of GH and IGF-1.

Papillary Thyroid Cancer Arising in Lateral Aberrant Thyroid Presenting with Multiple Metastases / 대한내분비학회지

Carcinoma of the thyroid usually presents as a palpable thyroid mass. However, in rare cases patients with thyroid cancer present with metastases of the cervical lymph node as the initial manifestation. The metastatic papillary tumor in cervical lymph nodes stained positive for thyroglobulin indicates the presence of a thyroid carcinoma, usually in the ipsilateral lobe. We herein report a case of multiple metastases in papillary thyroid carcinoma arising in the lateral aberrant thyroid with no evidence of thyroid carcinoma in the thyroid lobe.
