Abstract
A one-year old female baby presented to us with multiple itchy brownish papules and macules over the body since 3 months of age. The lesions started at the nape of neck and spread downwards involving trunk and limbs. She had been seen by various doctors but failed to respond to topical treatments. The baby was not on any long term medications and the parents could not recall specific precipitating events. Physical examination revealed multiple pigmented lesions involving the diaper area, trunk and four limbs. The skin lesions mainly consisted of papules each measuring 0.5-0.8 cm in diameter. There were some macular lesions which were new eruptions. Some of the old lesions may persist as papules with more dark brown colour or healed as post-inflammatory hyperpigmentation (Figure 1). Excoriations were noted. The abdomen was soft and no organomegaly was noted. There was no lymphadenopathy. Apart from the skin lesions, her general condition was good with up-to-date development. The family history was unremarkable.
