Definitions Disease- an abnormal condition of the body or the mind that causes dysfunction or discomfort. Disorder- a functional abnormality, or disturbance. Condition- a state of being, in health, a disease, such as a heart condition.
Prevalence The prevalence of skin disease in India is 10 to 12 percent of the total population with Eczema and Psoriasis being the major contributors. Due to pollution, ultraviolet light, and global warming, photosensitive skin disorders like pigment darkening, sunburn, skin cancers, and infectious diseases are increasing at a faster pace. A one percent reduction in ozone leads to a two to four percent increase in the incidence of tumors.
According to Ankit Goyal, Program Manager, Healthcare Practice, Frost & Sullivan, "The ecosystem for skin care treatment is witnessing a great change in demand patterns. Gone are the days, when skin care was limited to treatment of common skin diseases. The emergence of cosmetic and anti-aging treatments has changed the face of the skin care industry. The number of these cosmetic procedures is expected reach 18 to 20 lakh by 2015 in India.
In 2013, with prevalence rate of 10 percent, the population affected across India from skin disease is estimated at nearly 15. 1 crore. It is estimated that at a CAGR of 12 percent about 18. 8 crore people is likely to suffer from skin disease by 2015". At present, there about 6, 000 dermatologists catering to a population of over 121 crore. This means that for every 100, 000 people, only 0. 49 dermatologists are available in India as compared to 3. 2 in many states of the US. "

Other skin lesion Diagnosis: Skin biopsy or scraping may be performed to rule out other disorders and to confirm the diagnosis. Management: Topical agents eg. mineral oil, petroleum jelly, calcipotriol Phototherapy Systemic agents Surgery: removal of the tonsils may benefit people with chronic plaque psoriasis, guttate psoriasis, and palmoplantar pustulosis
Acne vulgaris Acne vulgaris (or simply acne) is a long-term skin disease that occurs when hair follicles become clogged with dead skin cells andoil from the skin. Acne vulgaris is a common skin disease that affects 85 -100% of people at some time during their lives.

If the diagnosis is uncertain, direct microscopy of a potassium hydroxide preparation of a skin scraping (known as a KOH test) can confirm the diagnosis of athlete's foot and help rule out other possible causes, such as candidiasis, pitted keratolysis, erythrasma, contact dermatitis, eczema, or psoriasis. A Wood's lamp (black light), although useful in diagnosing fungal infections of the scalp. Treatment: Topical eg. miconazole nitrate, clotrimazole, tolnaftate Oral eg. Terbinafine, Fluconazole or itraconazole
Urticaria (from the Latin urtica, "nettle" from urere, "to burn"), commonly referred to as hives, is a kind of skin rash notable for pale red, raised, itchy bumps.

Mild cases may be treated with bactericidal ointment, such as mupirocin. Severe cases require oral antibiotics, such as dicloxacillin, flucloxacillin, or erythromycin. Alternatively, amoxicillin combined with clavulanate potassium, cephalosporins (first-generation) and many others may also be used as an antibiotic treatment.
Carbuncles A skin abscess, a collection of pus that forms inside the body. It is usually caused by bacterial infection, most commonly with Staphylococcus aureus or Streptococcus pyogenes, which can turn lethal. Causes: The initial cause of a carbuncle can often not be determined.
