Skin Biopsy in Clear Lake, League City, Friendswood, Pasadena, TX
Clear Lake Dermatology performs skin biopsies for patients in the Pasadena, TX and League City, TX. Skin biopsies are often taken whenever the results of an initial exam are inconclusive. A biopsy may be performed on any abnormal skin growth and involves removing a small amount of tissue and then sending it to a laboratory for further testing.
Skin Biopsy Procedure
Before undergoing a biopsy, patients will be given a local anesthesia by injection. This helps to numb the area where the biopsy will occur so that an incision can be made. Once the area is completely numb, one of the doctors at Clear Lake Dermatology will remove tissue by one of three different methods:
Shave Biopsy – This procedure requires the use of an instrument that resembles a curved razor blade or a very small scalpel. In a shave biopsy, doctors will essentially “shave” a few cells from the top of a skin lesion, thereby leaving the rest of the growth intact.
Punch Biopsy – Requires the use of an instrument that resembles a cookie cutter to remove cells from the center of a growth.
Excisional Biopsy – Involves removing the entire growth along with a bit of surrounding tissue. It is performed whenever a growth is being removed as a precautionary measure and requires the use of sutures to close the wound.
After the Biopsy
Once the samples have been obtained, they are then sent to a laboratory for further analysis. A dermatopathologist at the laboratory will analyze the tissue and then prepare a pathology report detailing the results of this test. This report is normally available within four to 10 days after the tissue is sent to the laboratory.
