Punch biopsy,, periocular, tumors.
Brief summary
The purpose of this study was to identify accuracy rates of 2mm punch biopsy technique in diagnosing periocular malignancy.
Detailed description
In each case, the histology obtained at biopsy was compared with that identified at the time of tumor excision.
Interventions
PROCEDUREPunch Biopsy
1. Instillation of anesthetic eye drops. 2. Asepsis 3. Placement of surgical cloths and drapes 4. Infiltration of the involved region with anesthetic solution plus adrenalin in1:200.00 dilution. 5. Trephination of the most typical area of the lesion with a punch (2mm in diameter) of stainless steel by applying gentle pressure and twisting the trephine until its introduction into the suspicious lesions 6. Removal of the excised tissue with the aid of an insulin needle or conjuntival forceps, the base then bein cut with an number 11 surgical blade
