Primary purpose diagnostic
Arm
(Experimental)
punch biopsy Punch 2 mm
Instillation of anesthetic eye drops. Asepsis Placement of surgical cloths and drapes Infiltration of the involved region with anesthetic solution plus adrenalin in1:200.00 dilution. 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 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

Primary Outcomes

Measure
accuracy, positive predictive value, negative predictive value, sensitivity, specificity
time frame: In each case, the histology obtained at biopsy was compared with that identified at the time of tumor excision.

Eligibility Criteria

Male or female participants of any age.

Inclusion Criteria: - All lesions were initially examined at the slitlamp, after which lesions with malignant characteristics such as texture, size or color alterations asociated with ulceration, prominent borders or elevated contours, irregular borders, telangiectasias or loss of eyelashes were included. Exclusion Criteria: - Lesions with not malignant characteristics
