<human>: hi doctor, my father who is 54 years old his undergoing dialysis for two years. He has a cyst/lump on his arm but after a while it vanished and he noticed another lump on his leg and also on his genital area. He said it is not painful unless you press and put pressure. What do you think it is?do we need to worry and consult a doctor right away? thank you doctor hope you can enlighten me about this.
<bot>: Hi! Thanks for sharing your fathers' health problem relating to recurrent lumps! After going through your description of his spontaneous and vanishing recurrent lumps on random areas in his body parts including genital areas and with history of dialysis, if I were your family physician, I would like to consider following possibilities:1. Gouty tofu could be related to high uric acid level2. Skin edema due to renal failure3. Small hematomas4. Bursa like benign skin cysts5. Lymph nodes due to infections or cancer6. Malignancy7. Other cystic lesions could be neoplastic8. Spontaneous skin boils/subacute infectionsTherefore, these lumps could well be related to some underlying severe disease even cancer or spontaneous infections as complications of dialysis; please see his urologist ASAP for a needle biopsy to confirm and relieve your concerns;Wishing your father good health.
