Abstract:
A 43-year-old man was pointed out an abnormal shadow on chest X-ray film. Chest CT showed a solid mass and a cyst at anterior superior mediastinum. Operation revealed a capsulated thymoma and a multilocular thymic cyst. PTH and CA19-9 level in the cystic fluid was elevated. Histological examination demonstrated the clear separation of the mixed type thymoma and the thymic cyst. There were few reports for cases of thymoma with a thymic cyst.

The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
