<s>[INST]My 13-year old daughter has lumps on her armpit. They fade for awgile but contines to grow esp on her left armpit.  One time, i saw blood stains on her blouse from this spot.  She is a bit overweight?  Is there any relation to her weight and hormonal change?  Or hair follicle is blocked as no hair has come out yet.Thank you.[/INST]Hi! Thanks for writing to us sharing your daughters' health problem! After going through your description, I might summarize her axillary lumps as recurrent spontaneous and with bleeding openings; therefore, I must consider following possibilities in this case:1. Fibrocystic changes in the ectopic breast tissues in the maxilla; could be related to hormonal effects2. Hi Chat Doctor.  Hair folliculitis4. Enlarged lymph nodes due to minor infection or could be tuberculosis also5. Small infected sebaceous cystsTherefore, a clinical examination and possibly a needle biopsy is necessary in this case; please see her surgeon or physician today and if necessary write to us with feedback!regards,</s>
