Hello Sir.
Would it be possible to send me all USMLE questions you are posting?, i would be thankful
Dr. Abid, excisional biopsy when all the tumor is removed and sent to the lab as in malignant melanoma and most of skin cancers. Incisional when a part of it is removed and sent. Wedge biopsy is considered when the lesion is removed with a wedge of normal surrounding tissue. I wish this answers your question. Thank you Dr.
Sir please give me list of important cases where excisional , incisional and wedge biopsy is performed. These terms confuse me alot in questions
