How I use coal tar in dermatology.

Coal tar has been used in dermatology for over a hundred years. It was the main therapeutic agent for the treatment of various skin orders before the introduction of topical steroid. Since the advent of topical steroid the use of coal tar has reduced considerably. It is still being used a lot in the treatment of psoriasis. In this paper I will describe how I use coal tar not only in psoriasis, which is well known, but also in acne, folliculitis, eczema and seborrheic dermatitis and vitiligo, which are less well known.
