Ans:A.)It is related to Seborrhea.
The patient in question is suffering from Seborrheic Dermatitis.
SEBORRHEIC DERMATITIS
The term covers at least three common patterns of eczema, mainly affecting hairy areas, and often showing characteristic greasy yellowish scales. These patterns may merge together:
- A red scaly or exudative eruption of the scalp, ears ,face and eyebrows. May be associated with chronic blepharitis and otitis externa.
- Dry scaly ‘petaloid’ lesions of the presternal and interscapular areas. There may also be extensive follicular papules or pustules on the trunk (seborrhoeic folliculitis or pityrosporum folliculitis).
- Intertriginous lesions of the armpits, umbilicus or groins, or under spectacles or hearing aids.
In the first week of life, it typically occurs in the scalp (“cradle cap”), face, or groin.
In adults, it is seen in patients with Parkinson’s disease, CVA and HIV infection.
Most common site is the scalp : recognized as dandruff.
Cause:
- This condition is not obviously related to seborrhoea.
- The success of treatments directed against yeasts has suggested that overgrowth of the pityrosporum yeast skin commensals plays an important part in the development of seborrhoeic eczema.
Treatment
- Therapy is suppressive rather than curative.
- Topical antifungal,topical steroids, 2% sulphur and 2% salicylic acid .
- Medicated shampoo, which may contain ketoconazole, tar, salicylic acid, sulphur, zinc or selenium sulphide.
- For intertriginous lesions a weak steroid – antiseptic or steroid – antifungal combination is often effective.
- For severe and unresponsive cases a short course of oral itraconazole may be helpful.
