Seborrheic Dermatitis : What Is It ? Clinical Presentation with Diagnosis Management and Natural Treatment

Seborrheic dermatitis is a papulosquamous disorder patterned on the sebum-rich areas of the scalp, the face, and the trunk. In addition to sebum, this dermatitis is linked to Pityrosporum ovale, immunologic abnormalities, and activation of complement. It is commonly aggravated by changes in humidity, trauma (eg, scratching), seasonal changes, and emotional stress. The severity varies from mild dandruff to exfoliative erythroderma. Seborrheic dermatitis may worsen in Parkinson disease and in AIDS.

Seborrheic dermatitis is associated with normal levels of P ovale but an abnormal immune response.
The incidence of seborrheic dermatitis is 3-5%, with a worldwide distribution. In infants, it occurs as cradle cap or commonly as a flexural eruption or rarely as erythroderma.

Clinical presentation

Skin lesions present as greasy scale over red, inflamed skin. Infectious eczematoid dermatitis, with oozing and crusting, suggests secondary infection. A seborrheic blepharitis may occur independently.
Distribution follows the oily and hair-bearing areas of the head and the neck, such as the scalp, the forehead, the eyebrows, the lash line, the nasolabial folds, the beard, and the postauricular skin. Presternal or interscapular involvement is more common than the nonscaling intertrigo of the umbilicus, axillae, inframammary and inguinal folds, perineum, or anogenital crease that may also be present.

Pityrosporum organisms are probably not the cause but a cofactor linked to a T-cell depression, increased sebum levels, and an activation of the alternative complement pathway.

Because seborrheic dermatitis is uncommon in preadolescent children, and Tinea capitis is uncommon after adolescence, dandruff in a child is more likely to represent a fungal infection. Commonly seborrheic dermatitis is secondarly infected by bacteria.

Treatment

Topical corticosteroids, creams, lotions Systemic ketoconazole or shampoos can be given if it is sever.

Dandruff responds to more frequent shampooing. Salicylic acid, tar, selenium, sulfur, and zinc all are effective in shampoos and may be alternated. Selenium sulfide (2.5%) or ketoconazole shampoos may help by reducing P. ovule scalp reservoirs. When sever Ketokonazole 200mg tab can be given for 2 to 3 week and Antibiotics if it is infected
