A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
Sebaceous carcinoma is a neoplastic growth of sebaceous glands. It is predominantly seen in the head and neck region given the high density of sebaceous glands in this region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, is the most common site accounting for up to 75% of SGc. [6]
A review of historical literature shows that Spence himself never wrote that adipose or breast-tissue extends into the axilla. He only published that surgeons should not operate on breast cancer if they found "an undefined tail-like projection creeping up from the breast towards the axilla”, as though referring to the tumor tissue itself.

Sweat glands are distributed all over the body except nipples and outer genitals. Although the nipples do have the mammary glands, these are known as modified sweat glands. Sebaceous glands are typically found in the opening shafts of hair. They are not on the palms of the hands or the soles of the feet.
These may be positive for alpha smooth muscle actin and can contract and expel the secretions of exocrine glands. They are found in the sweat glands, mammary glands, lacrimal glands, and salivary glands. Myoepithelial cells in these cases constitute the basal cell layer of an epithelium that harbors the epithelial progenitor.
Salivary gland–type carcinoma of the thyroid, also termed intrathyroidal mammary analog secretory carcinoma, has been reported in 12 cases in the English language. [12] In a review of 11 cases, salivary gland–type carcinomas of the thyroid were diagnosed in adult females (9 cases) and males (2 cases) with an average age 61.5 years (range ...
Worldwide, breast cancer is the leading type of cancer in women, accounting for 25% of all cases. [5] It is most common in women over age 50. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. [6]
The four types of PCB are defined and diagnosed in part by several of their microscopic features including: 1) the presence of tumor invasion into adjacent normal tissues; 2) the presence and location of myoepithelial cells, i.e. cells that normally rest on the basement membrane of mammary gland ducts and function to contract and thereby expel ...
