Histopathological Comparison Between Superficial Pressure Ulcers and Incontinence-associated Dermatitis

Two punch biopsies will be performed in each patient, one at the border of the skin lesion, and one at the adjacent healthy skin. A disposable biopsy punch of 4 mm will be used. A biopsy punch is a small circular blade (like an apple corer) which is rotated into the skin to obtain a cylindrical specimen. Local anaesthesia will be applied and the circular wound will be closed by a single suture. Sutures will be removed after one week.
