Abstract:
Macrofollicular encapsulated papillary thyroid carcinoma (MEPC) is a rare variant of papillary carcinoma of thyroid with a favourable clinical course. It could be mistaken for a follicular neoplasm or a hyperplastic nodule. We report cytological and histopathological features of this rare variant of papillary carcinoma in a 22 year old female with brief review of literature.

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...

Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
