Chronic folliculitis of legs, though not uncommon in India, is not frequently seen in the same expatriate population in Gulf. This is a case I saw few days back. However he complained that lesions appeared only when he is in gulf and disappeared completely while in India! PUVA and Co-Trimoxazole have found to be useful in reducing recurrence. Co-Trimoxazole retains high sensitivity in this region probably because of decreased use.
