Superficial Granulomatous Pyoderma
Superficial granulomatous pyoderma is a cutaneous condition, a variant of pyoderma gangrenosum characterized by a localized superficial vegetative or ulcerative lesion, which usually follows trauma, such as surgery. Signs and symptoms In superficial granulomatous pyoderma, ulcers typically have a clean base and vegetating borders, making them more superficial. Unlike pyoderma gangrenosum, superficial granulomatous pyoderma is more frequently associated with truncal involvement and is not always linked to underlying systemic disease.

Dermatology
Dermatology is the branch of medicine dealing with the skin.''Random House Webster's Unabridged Dictionary.'' Random House, Inc. 2001. Page 537. . It is a speciality with both medical and surgical aspects. A dermatologist is a specialist medical doctor who manages diseases related to skin, hair, nails, and some cosmetic problems. Etymology Attested in English in 1819, the word "dermatology" derives from the Greek δέρματος (''dermatos''), genitive of δέρμα (''derma''), "skin" (itself from δέρω ''dero'', "to flay") and -λογία '' -logia''. Neo-Latin ''dermatologia'' was coined in 1630, an anatomical term with various French and German uses attested from the 1730s. History In 1708, the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, and the first textbooks (Willan's, 1798–1808) and atlases ( Alibert's, 1806–1816) appeared in print around the same time.Freedberg, et al.

Pyoderma Gangrenosum
Pyoderma gangrenosum is a rare, inflammatory skin disease where painful pustules or nodules become ulcers that progressively grow. Pyoderma gangrenosum is not infectious. Treatments may include corticosteroids, ciclosporin, infliximab, or canakinumab. The disease was identified in 1930. It affects approximately 1 person in 100,000 in the population. Though it can affect people of any age, it mostly affects people in their 40s and 50s. Types There are two main types of pyoderma gangrenosum: * the 'typical' ulcerative form, which occurs in the legs * an 'atypical' form that is more superficial and occurs in the hands and other parts of the body Other variations are: * Peristomal pyoderma gangrenosum comprises 15% of all cases of pyoderma * Bullous pyoderma gangrenosum * Pustular pyoderma gangrenosum * Vegetative pyoderma gangrenosum Presentation Associations The following are conditions commonly associated with pyoderma gangrenosum: * Inflammatory bowel disease: ** Ulcerativ ...

PAPA Syndrome
PAPA syndrome is an acronym for pyogenic arthritis, pyoderma gangrenosum and acne. It is a rare genetic disorder characterised by its effects on skin and joints. Signs and symptoms PAPA syndrome usually begins with arthritis at a young age, with the skin changes more prominent from the time of puberty. The arthritis is the predominant feature, noted by its juvenile onset and destructive course. Individuals often recall episodes of arthritis precipitated by a traumatic event. With repeated episodes the joints become damaged with multiple joint replacements required. Hopefully, with improved treatment options, the damage will be limited in new cases. Pyoderma gangrenosum is variably expressed, which means that it is not always present in all individuals with the disease. It presents as poorly healing ulcers with undermined edges. Pathergy is an important feature (this term refers to the tendency of ulcers to arise at points of injury). There are reports of lesions developing at the ...

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 mesoderm th ...
