Skin biopsy

Skin biopsy is a diagnostic method used to assist the physician when they have insufficient criteria to place an accurate diagnosis.

The procedure involves taking a piece (2-4 mm) from the affected area of the skin or skin growth, followed by histological testing. Depending on your condition, there are four ways to perform a biopsy:

Punch biopsy – performed with a special surgical instrument called a punch.

Shave biopsy – the surface layer of a skin section is removed, leaving a surface wound that heals, leaving a scab.

Deep biopsy – performed using a scalpel to sample deep subcutaneous pathological processes. It is then stitched up; the stitches are removed in 7-10 days.

PAP smear – “scraping” the surface skin layer cells, “smearing” the sample on a microscope slide and performing histological testing.


It is recommended to suspend therapy for at least a week before undergoing a skin biopsy.
Histology results are ready in one week at the earliest.

Възможните странични ефекти са кървене, преходна болка и оток, кожни инфекции, отпускане на конците, образуване на надигнат белег, алергична реакция към анестезията.

After the procedure, it is recommended not to wet the area for the first 24 hours. Change the dressing when soiled.
