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 m ...

Palisaded Encapsulated Neuroma
Palisaded encapsulated neuroma (PEN) is a rare, benign cutaneous condition characterized by small, firm, non-pigmented nodules or papules. They typically occur as a solitary (single) lesion near the mucocutaneous junction of the skin of the face, although they can occur elsewhere on the body. Symptoms PEN tumours are always painless, solid masses felt on the skin that, due to their slow-growing nature, typically take many years to grow to a size where they are noticeable. There are never any symptoms associated with systemic disease. Diagnosis As mentioned previously, PEN is a benign, firm, flesh-coloured lesion that typically occurs in dermis of the skin of the face. The lesions are typically between 2–6mm and are slow-growing. On the face, the lesions can be found on the eyelid, nose and in the oral mucosa, however, the lesions can also occur on the shoulder, arm, hand, foot and the glans of the penis. PEN is diagnosed by clinical recognition of the lesion and on subs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
