==== Six layers of skin ====
+
In the context of ''kushtha'', Ayurveda acknowledges that the human skin consists of six layers, and each layer is seat of specific type of gradually progressing ''kushtha'':
 
+
#First layer ''udakadhara'', external most layer is responsible for water metabolism. Initial pathology of minor types of ''kushtha'' starts with excessive sweating/ discoloration/itching swelling/ altered tactile sense in prodromal stage of ''kushtha'' indicative of impairment of water metabolism. This layer may be correlated with stratum corneum.  
In the context of ''kushtha'', it is important to note that Ayurveda acknowledges that there are six layers of skin, and each layer serving as a site or seat of ''kushtha'':
+
#Second layer is ''asragdhara'', which contains the blood metabolites and impurities of blood trigger the pathology of ''kushtha'' and manifest as –bluish black, red, rashes/ pricking pains/ and ulceration. This layer may be correlated with stratum lucidum,  
 
+
#The third layer of skin is the seat of ''sidhma'' and ''kilas kushtha''.The third layer  may be correlated with stratum granulosum.

#The fourth layer is seat of dadru and krushtha. 4th layer may be correlated with stratum germinosum (combination of spinosum and basale layers),  
#The second layer is Asragdhara, which contains the blood metabolites and impurities of blood trigger the pathology of ''kushtha'' and manifest as –bluish black, red, rashes/ pricking pains/ and ulceration. This layer may be correlated with stratum lucidum,

(5) Fifth layer of skin is seat of makushtha and severe dermal pathologies. 5th layer may be correlated with Papillary layer.  
#The third layer of skin is the seat of ''sidhma'' and ''kilas kushtha''. The third layer  may be correlated with stratum granulosum.
+
(6) Sixth layer is the seat of most severe mahakushtha, which are incurable. 6th layer may be compared with Reticular layer.                                                                       (Ch. Sharir 7/ 4)
#The fourth layer is seat of ''dadru'' and ''krushtha''. The fourth layer may be correlated with stratum germinosum (combination of spinosum and basale layers),

It is rūkṣa, paruṣa, khara in nature which signifies the increase of rūkṣa, khara guna at the level of skin. Roughness, dryness increases when there is destruction of sweat glands (dusti of ambu dhatu), decrease in essential fatty acids (reduce snigdhata of meda inturn kapha), proliferation of keratinocytes. Primary lesion manifest in the form of dry, rough and blackish brownish colour. Secondary lesion includes loss of sensation (due to degeneration of nerve endings or less nutrition to the nerve tissue due to atherosclerosis or reduce blood supply) severe pricking pain (nistōda) itching, burning sensation and pustular presentation. Thus conditions of non erythematous eczema, keratosis, atrophic actinic keratosis, non hypertrophic keratosis, seborrhic conditions can be understood in kapāla kuṣṭha.

2. Udumbara kuṣṭha:
==== Patho-physiology of ''kushtha'' ====
+
It is pitta dominated kuṣṭha. Hyperpigmentation, increased vasocongestion, burning, pain and pus formation are the symptoms and signs.
 
+
Primary lesion manifests as red in colour associated with pus, burning sensation caused mainly due to pitta and rakta. Usna and tiksna guna is responsible for the same.
===== 1. ''Kapāla Kuṣṭha'' =====
+
Secondary lesion includes kleda, kotha, body hair attains brownish colour, excessive secretion due to sasneha, sara and drava guna of pitta and rakta.
 
+
Thus infective and inflammatory phase is being explained. Increased flow of inflammatory factors causes rise in temperature, redness and burning sensation. Eczema is inflammation of the skin. It is characterized by erythematous, vesicular, weeping, itchy and crusting patches. The condition is caused by dysfunctional interplay between the immune system and skin.
It is ''rūkṣa, paruṣa, khara'' in nature which signifies the increase of ''rūkṣa, khara guna'' at the level of skin. Roughness, dryness increases when there is destruction of sweat glands (''dusti'' of ''ambu dhatu''), decrease in essential fatty acids (reduce ''snigdhata'' of ''meda'', in turn, of ''kapha''), proliferation of keratinocytes. Primary lesion manifest in the form of dry, rough and blackish brownish color. Secondary lesion includes loss of sensation (due to degeneration of nerve endings or less nutrition to the nerve tissue due to atherosclerosis or reduce blood supply) severe pricking pain (''nistōda'') itching, burning sensation and pustular presentation. Thus conditions of non erythematous eczema, keratosis, atrophic actinic keratosis, non hypertrophic keratosis, seborrhic conditions can be understood in ''kapāla kushtha''.

+
Itis predominated by kapha dōṣa. The sthira, snigdha guna brings about sthirata and snigdhata to the kuṣṭha. Therefore the lesion is granulomatous in presentation. The early and indeterminate leprosy especially Lepromatous leprosy is a skin condition consisting of pale macules. It results from failure of Th1 cell activation which is necessary to eradicate the mycobacteria. In Lepromatous Leprosy Th2 response is turned on and because of reciprocal inhibition the cell mediated response is depressed.

4. Rushyajivha kushtha:
It is ''pitta'' dominated ''kuṣṭha''. Hyper-pigmentation, increased vaso-congestion, burning, pain and pus formation are the symptoms and signs.
+
It is dominated by vāta and pitta dōṣha. Vāta dōṣha brings roughness, pain whereas pitta is responsible for the discolouration, burning sensation whereas both the dōṣha are responsible for ashugati and samuthan.
 
+
Thus inflammatory and degenerative changes dominate the condition. Pathogenesis involving infective origin or allergic origin may be included. Diseases such as Lyme disease may be included. Expanding redness known as erythema migrans begins at the site of bite after a period of one week. There is no much itching i.e. alpa kandu but the rash is red and warm but generally painless. Classically the innermost portion remain darker red and becomes indurated (is thicker and firmer).
Primary lesion manifest as red in color associated with pus, burning sensation caused mainly due to ''pitta'' and ''rakta''. ''Usna'' and ''tiksna guna'' is responsible for the same.
+
5. Pundarika kushtha:
 
+
It is dominated by pitta and kapha. Pitta is responsible for redness, burning sensation, pāka (..), pus formation whereas kapha is responsible for whitish nature, itching and kr̥mi.
Secondary lesion include ''kleda, kotha,'' body hair attains brownish color, excessive secretion due to ''sasneha, sara'' and ''drava guna'' of ''pitta'' and ''rakta''.
+
Primary lesion manifest as “rakta rāji sirā santata utsedavanti” i.e. vessel are inflamed and are palpable. Systemic vasculitis may affect the skin and vascular damage may be the main feature in several skin diseases. The histological features that are common are:- Vessel wall damage , red cell extravasation, invasion of inflammatory cells into vessel walls.

It is characterized by erythematous, vesicular, weeping, itchy and crusting patches. The condition is caused by dysfunctional interplay between the immune system and skin.
+
It is dominated by vāta kapha dōṣha, fine powder falls after scratching and resembles colour similar to flower of alābū. The specialty of disease is that it is mainly seen in urabhāga i.e. trunk. Tinea versicolar is a condition characterized by a skin eruption on the trunk and proximal extremity. The symptoms of this condition include; fine scaling of the skin producing a very superficial ash like scale. Pale (sveta), dark tan (arun), pink in colour (shukla rakta avabhasani) with a reddish undertone (tamra) that can darken when the patient is overheated, such as in a hot shower or during/ after exercise, tanning typically makes the affected areas contrast more starkly with the surrounding skin leading to sharp borders. In people with dark skin tones, pigmentary changes such as hypopigmentation (loss of colour) are common while in those with lighter skin colour hyperpigmentattion (increase in skin colour) is more common. The yeast is thought to feed on skin oils (lipids) as well as dead skin cells.

Squamous cell carcinoma or squamous cell cancer or epidermoid carcinoma or squamous cell epithelioma is a cancer of a kind of epithelial cell, the squamous cell. These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of the skin cancer. However, squamous cells also occur in the lining of the digestive tract, lungs and other areas of body and squamous cell carcinoma occurs as a form of cancer in diverse tissue such as lips, mouth, oesophagus, urinary bladder, prostrate, lung, vagina and cervix. Despite sharing the name squamous cell carcinoma there may be tremendous differences in presenting symptoms, natural history, prognosis and response to treatment. It arises from the uncontrolled multiplication of cells of epithelium, or cells showing particular cytological or tissue architectural characteristic of squamous cell differentiation, such as the presence of keratin, tonofilament bundles or dermosomes structures involved in cell to cell adhesion. This non melanoma skin cancer may appear as a firm red nodule, a scaly growth that bleeds or develops a crust or a sore that doesn’t heal.

Stimulation of acetylcholine and further ionic changes caused thereafter are responsible for sweating. Lack of such impulse also causes reduced sweating. Astanga Sangrahakar has explained role of vyan vāyu in sweda which when hampered leads to anhidrosis.

Research shows that in diabetic patient thickness of skin is observed reason being collagen bundles become large, disorganized and separated by clear spaces. Small amount of acid mucopolysachrides may be present in upper reticular dermis. Presence of active fibroblast and extensive collagen polymerization in the rough endoplasisic reticulam may be the pathogenesis for thick skin.

Calcium deposition may also be cause for tough and thick skin. Rūkṣata, kharata, guna of vāta and shita guna of vāta and kapha alongwith increase of guruta, manda and sthira guna of kapha contribute to thickening of skin. Khara is also property of asthi dhatu which is generated by interplay between prithvi, agni and vāyu. Here calcium is representative of prithvi mahabhut. So prithvi mahabhut bhuyista āhar or increased parthivagni can lead to increased absorption of calcium from gastrointestinal tract.

Granulation tissue appearance is light red or dark pink in colour (śyāva), being perfused with new capillary loops or buds granular in appearance. Formation of extracellular matrix gives it hard touch and abnormal productions of skin cells (especially during wound repair) leading to overabundance of skin cells. Premature maturation of keratinocytes induced by an inflammatory cascade in the dermis also contributes for the same.

Cracked skin is often kicked off by a vicious cycle of events starting off as a minor, but leading to painful deep cracks. Plain old dry skin can lead to scaling, scaling can cause itchiness leading to scratching and scratching can cause inflammation and tears of skin that can become fissures which leads to more irritation and pain.

Healthy skin has slightly acidic pH, exposure to substances with an alkaline pH such as many commercial cleansers and hand soaps also contribute to interruptions of skin integrity. Once the skin integrity is disturbed, a homeostatic repair mechanism is stimulated that causes the rapid repair of barrier function. Continued exposure to alkaline substances will slow down repair by inhibiting normal skin acidity when there is continued exposure to unfavourable environmental factors.

It is caused by kapha dominated condition. Kapha by its snigdha, guru, mridu and sita guna when increased above normal condition it leads to obstructive changes at the integumentary system. Reduced blood supply causes blackish brown discolouration. Further obstructive changes reduce the local immunity and give a chance for dermatophytes to penetrate the skin barrier. It results in eruptions and thereby causing excessive exudation. Secondary infection and reduced blood supply is cause for pruritus. It can be compared with wet eczema.
