Cutaneous Horn
Cutaneous horns, also known by the Latin name ''cornu cutaneum'', are unusual keratinous skin tumors with the appearance of horns, or sometimes of wood or coral. Formally, this is a clinical diagnosis for a "conical projection above the surface of the skin." They are usually small and localized but can, in very rare cases, be much larger. Although often benign, they can also be malignant or premalignant. Signs and symptoms The lesion at the base of the keratin mound is benign in the majority of cases. Malignancy is present in up to 20% of cases, with squamous-cell carcinoma being the most common type. The incidence of squamous-cell carcinoma increases to 37% when the cutaneous horn is present on the penis. Cause The cause of cutaneous horns is still unknown, but it is believed that exposure to radiation can trigger the condition. This is evidenced by a higher rate of cases occurring on the face and hands, areas that are often exposed to sunlight. Moreover, there is a higher pr ...

Keratin
Keratin () is one of a family of structural fibrous proteins also known as ''scleroproteins''. It is the key structural material making up Scale (anatomy), scales, hair, Nail (anatomy), nails, feathers, horn (anatomy), horns, claws, Hoof, hooves, and the outer layer of skin in vertebrates. Keratin also protects epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong mineralization (biology), unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. Excessive keratinization participate in fortification of certain tissues such as in horns of cattle and rhinos, and armadillos' osteoderm. The only other biology, biological matter known to approximate the toughness of keratinized tissue is chitin. Keratin comes in two types: the primitive, softer forms found in all vertebrates and the harder, derived forms fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the Human body, body and composed of Human skin, skin, hair, Nail (anatomy), 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 (skin), 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. Embryology, In the embryo, the epidermis, hair, and glands form from the ectod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidermodysplasia Verruciformis
Epidermodysplasia verruciformis (EV) is a skin condition characterised by wart, warty skin lesions. It results from an abnormal susceptibility to HPV infection (HPV). It is associated with a high lifetime risk of Squamous cell skin cancer, squamous cell carcinomas in skin. It generally presents with scaly macule, spots and papule, small bumps particularly on the hands, feet, face, and neck; typically beginning in childhood or a young adult. The bumps tend to be flat, grow in number, and then merge to form plaques. On the trunk, it typically appears like pityriasis versicolor; lesions are slightly scaly and tan, brown, red, or looking pale. On the elbows, it may appear like psoriasis. On the forehead, neck, and trunk, the lesions may appear like seborrheic keratosis. It is most frequently genodermatosis, inherited as an autosomal recessive trait, with some reports of autosomal dominant and X-linked inheritance. Other types include atypical EV which develops due to mutation, gene mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinic Keratosis
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, is a Premalignant condition, pre-cancerous area of thick, scaly, or crusty skin.Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. . Actinic keratosis is a disorder (''wiktionary:-osis, -osis'') of Epidermis, epidermal keratinocytes that is induced by Ultraviolet, ultraviolet (UV) light exposure (''wiktionary:actin-, actin-''). These growths are more common in Light skin, fair-skinned people and those who are frequently in the sun. They are believed to form when skin gets damaged by UV radiation from the sun or indoor tanning beds, usually over the course of decades. Given their pre-cancerous nature, if left untreated, they may turn into a type of skin cancer called Squamous cell skin cancer, squamous cell carcinoma. Untreated lesions have up to a 20% risk of progression to squamous cell carcinoma, so treatment by a dermatologist is recommended. Actin ...

Wart
Warts are non-cancerous viral growths usually occurring on the hands and feet but which can also affect other locations, such as the genitals or face. One or many warts may appear. They are distinguished from cancerous tumors as they are caused by a viral infection, such as a human papillomavirus, rather than a cancer growth. Factors that increase the risk include the use of public showers and pools, working with meat, eczema, and a weak immune system. The virus is believed to infect the host through the entrance of a skin wound. A number of types exist, including plantar warts, " filiform warts", and genital warts. Genital warts are often sexually transmitted. Without treatment, most types of warts resolve in months to years. A number of treatments may speed resolution, including salicylic acid applied to the skin and cryotherapy. In those who are otherwise healthy, they do not typically result in significant problems. Treatment of genital warts differs from that of o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulisse Aldrovandi
Ulisse Aldrovandi (11 September 1522 – 4 May 1605) was an Italian naturalist, the moving force behind Bologna's botanical garden, one of the first in Europe. Carl Linnaeus and the comte de Buffon reckoned him the father of natural history studies. He is usually referred to, especially in older scientific literature in Latin, as Aldrovandus; his name in Italian is equally given as Aldroandi. Life Aldrovandi was born in Bologna to Teseo Aldrovandi and his wife, a noble but poor family. His father was a lawyer, and Secretary to the Senate of Bologna, but died when Ulisse was seven years old. His widowed mother wanted him to become a jurist.

His interests successively extended to philosophy and logic, which he com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
