Patient's Query

Hi doctor,

I just had a horrible experience with a dermatologist. The surgery was today. I just wanted this test out for cancer. This bump appeared a few years ago in my thigh but started growing and got very dark and itchy, and sometimes it bled. I went for a scheduled surgery to remove a lump. I was injected with two types of medication to numb the leg. However was poked about ten times around the bump they were going to remove, then the nurse pressured the wound to what she said was to get the anesthesia to work. Also, the surgery tray she took out contained the biopsy bottle, but it was with the lid off. Could not this get contaminated? After the procedure, no antibiotic was prescribed. Should I be taking antibiotics? I am a heart patient and do not want to get any blood clots. I take Metroprolol now. Please advise if I should be taking antibiotics.

Welcome to icliniq.com.

I have read your concern.

The biopsy container contains formalin which is a strong disinfectant. So, nothing to worry about regarding the contamination part. Usually, a biopsy is done with all aseptic precautions. So no oral antibiotic is needed. Topical antibiotic is sufficient to take care of the wound. Things which you need to follow are not to wet the local area, antiseptic dressing alternate days with all aseptic precautions, and suture removal after seven to ten days, depending on the site of lesions.

I hope this addresses your concern.
