Neurofibromatosis and reticulate acropigmentation of Dohi: a case report.
A 13-year-old boy had progressive pigmentary changes affecting his limbs which began when he was 9 months of age. He also had a history of café au lait macules on his trunk since birth which were becoming more numerous. The diagnosis of reticulate acropigmentation of Dohi (dyschromatosis symmetrica hereditaria) and neurofibromatosis type 1 (NF-1) was made on the basis of the clinical features. To our knowledge, this is the first report of these two conditions occurring in the same patient.

Actinic prurigo, tropical (South-East Asian) variant.
Actinic prurigo is a chronic familial photodermatitis found predominantly among the Amerindians. It has been reported from North and South America, Britain and Japan. We report a case of actinic prurigo seen in Singapore. A 20-year-old Malay female presented with a persistent pruriginous eruption in the sun-exposed parts and on her abdomen. She also had lower lip cheilitis and thinning of the outer eyebrows, features often seen in actinic prurigo. The minimal erythema dose to ultraviolet A (UVA) and UVB were persistently lowered. We propose that this condition be called actinic prurigo, tropical (South-East Asian) variant.
