Eccrine Nevus
An eccrine nevus is an extremely rare cutaneous condition that, histologically, is characterized by an increase in size or number of eccrine Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelia ... secretory coils.Freedberg, et al. (2003).

Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eccrine Gland
Eccrine sweat glands (; from Greek ''ekkrinein'' ' secrete'; sometimes called merocrine glands) are the major sweat glands of the human body, found in virtually all skin, with the highest density in palm and soles, then on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads. They reach their peak of development in humans, where they may number 200–400/cm2 of skin surface.Bolognia, J., Jorizzo, J., & Schaffer, J. (2012). Dermatology (3rd ed., pp. 539-544). hiladelphia Elsevier Saunders. They produce a clear, odorless substance, sweat, consisting primarily of water. These are present from birth. Their secretory part is present deep inside the dermis. Eccrine glands are composed of an intraepidermal spiral duct, the "acrosyringium"; a dermal duct, consisting of a straight and coiled portion; and a secretory tubule, coiled deep in the dermis or hypodermis. The eccrine gland o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nevus Comedonicus
'' Nevus comedonicus'' (also known as a comedo nevus) is characterized by closely arranged, grouped, often linear, slightly elevated papules that have at their center keratinous plugs resembling comedones.James, William; Berger, Timothy; Elston, Dirk (2005).

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying meso ...

ILDS
The International League of Dermatological Societies (ILDS) is a non-governmental organization that works closely with the World Health Organization. It was founded in 1935, but because of World War II no congresses were held until 1952. It is governed by the International Committee of Dermatology. The ILDS is the parent organization of the International Foundation for Dermatology, founded in 1987. After the publication of ICD-10, the ILDS produced a series of compatible extensions for use in dermatology Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.''
