The subcutaneous tissue is a layer of fat between the dermis and underlying fascia. [14] This tissue may be further divided into two components, the actual fatty layer, or panniculus adiposus, and a deeper vestigial layer of muscle, the panniculus carnosus. [3] The main cellular component of this tissue is the adipocyte, or fat cell. [14]
Vitiligo (/ ˌ v ɪ t ɪ ˈ l aɪ ɡ oʊ /, vit-il-eye-goh) is a chronic autoimmune disorder that causes patches of skin to lose pigment or color. [1] The cause of vitiligo is unknown, but it may be related to immune system changes, genetic factors, stress, or sun exposure.
The skin weighs an average of 4 kg (8.8 lb), covers an area of about 2 m 2 (22 sq ft), and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are glabrous skin, the nonhairy skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [16]
Physicians use the history of the individual with the skin condition as well as other tests to identify which disorder is present. Other conditions that may be confused with seborrhoeic dermatitis based on appearance are listed below.

Poliosis circumscripta, commonly referred to as a "white forelock", is a condition characterized by localized patches of white hair due to a reduction or absence of melanin in hair follicles. Although traditionally associated with the scalp, poliosis can affect any hairy area on the body, including eyebrows, eyelashes, and beards.
A rash is a change of the skin that affects its color, appearance, or texture. A rash may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell, and may be painful. The causes, and therefore treatments for rashes, vary widely.
Adipocere was first described by Sir Thomas Browne in his discourse Hydriotaphia, Urn Burial (1658): [3]. In a Hydropicall body ten years buried in a Church-yard, we met with a fat concretion, where the nitre of the Earth, and the salt and lixivious liquor of the body, had coagulated large lumps of fat, into the consistence of the hardest castile-soap: wherof part remaineth with us.
A punch biopsy is done with a circular blade ranging in size from 1 mm to 8 mm. The blade, which is attached to a pencil-like handle, is rotated down through the epidermis and dermis, and into the subcutaneous fat, producing a cylindrical core of tissue. [1] An incision made with a punch biopsy is easily closed with one or two sutures. Some ...
