Abstract
Sixty-two cases of orbital and periorbital palpable neoplasms were analyzed cytologically. The material was obtained by our technique of simply introducing a fine injection needle in the tumor mass without aspiration. Fifty-six of these tumors had a subsequent histologic diagnosis by surgical procedure or biopsy. Forty-nine of the 56 cytologic diagnoses (87%) were concordant with the histologic findings with regard to malignancy and its variety. In three other cases the diagnosis of malignancy was only achieved by surgical procedure or biopsy (5%). In two cases, there were false-malignant results (4%), one corresponding to a meningioma and the other related to a reactive lymphoid hyperplasia. There was one false-benign (2%) result in a case of non-Hodgkin's lymphoma. In one patient, the cytologic material was insufficient for diagnosis (2%). In six other cases, the initial cytologic examination was ultimately confirmed either by biochemical studies or by biopsies of nodal metastases. No orbital hemorrhage was observed after fine-needle sampling. This outpatient technique is highly accurate and permits diagnosis in a few minutes. Diagn Cytopathol 1986;2:17-20.
