Dermatologist pl. tell me what diagnosis may be ?

a seven year girl having asymptomatic, soft ,skin coloured ,1.5 cm, oval in shape, papules ,bilateral symmetrical ,on all the proximal interphallengial joints ,since last year.|||Maybe it is a kind of rare lipid disorder disease (xanthomas). I had seen such a condition in one family and this was associated with juvenile arcus senilis.|||Are you sure you meant 1.5 cm or mm? If mm I would guess warts.|||I will ask my BIL who is a dermatologist and let you know.|||warts
