<s>[INST] thanks for your concern. my daughter is two years old.she is having two peanut  sized bulgings over tibia bone below the knee.i think they are painless because she is very active and never complained about it .iam very much worried . can any one tell me what it could be. [/INST] Hi.... by what you quote I feel that it could be small lipoma or a dermoid cyst or fibrous cyst which are appearing like small nodules below the knee joint. As this is not causing any discomfort you need not worry. Nevertheless I suggest that you consult your pediatrician regarding this.Regards - Dr. Sumanth </s>
