Abstract:
The apocrine type of encapsulated papillary carcinoma (ECP-A), of the breast is a rare neoplasm and there are only eight cases reported to date. Herein, we report the ninth case. A 68-year-old Japanese woman presented with a left breast mass. The cytoplasm of the tumour cells showed positive immunostaining for GCDFP-15. Myoepithelial cells were absent within the papillary structures and at the periphery of the lesion. The clinical course of the patient was uneventful 11 months after surgery. We postulate that EPC-A belongs to the molecular apocrine type of breast carcinoma.

01:12The Mammary Glands
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
01:11Papillary 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
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
