The biopsy was performed under local anesthesia and following the technique described by Daniels. This technique consists of everting the upper lip and performing a 1.5 to 2 cm incision on the labial mucosa, between the midline and the corner, penetrating into the epithelium and releasing the glands from the surrounding fascia. A direct dissection is undertaken, glands are separately removed and placed in 10% formalin. The procedure is then completed with the suture of the incision. Harvested glands were sent to the hospital's Pathological Anatomy Service, to be routinely processed and dyed with hematoxylin and eosin.
