Fine needle aspiration cytology of eyelid tumors.

Fine needle aspiration (FNA) biopsy was performed on 19 patients with eyelid masses. Six of the patients also had preauricular/submandibular nodal enlargements aspirated. Histopathologic study was performed in ten of the cases. FNA cytology made the diagnosis of an epithelial malignancy in 17 cases (10 sebaceous carcinomas, 4 poorly differentiated carcinomas, 2 squamous cell carcinomas and 1 malignant melanoma). The diagnostic accuracy of FNA cytology in evaluating eyelid masses was thus 89.4%; there were two false-negative cases. All nodal FNA smears revealed metastases of the respective primary tumors. This study indicated that FNA cytology is a simple and efficient method for making the diagnosis of malignancy in eyelid masses, especially in those patients who are not suitable candidates for surgery. Subsequent nodal metastases and tumor recurrence were detected without difficulty using FNA smears.
