The cytological,immunocytochemical and molecular genetic analysis in diagnosis of the neoplasms of the eye,eye adnexa and orbit

The fine needle aspiration biopsy was performed in 91 patients including 57 cases of retrobulbar tumors done under CT control. All aspirates were cytologically examined. In 21 cases immunocytochemical examination was performed in order to distinguish poorly differentiated neoplasms. In 19 cases malignant lymphoma was distinguished from pseudolymphoma. Cytological diagnosis was confirmed by histopathological examination in 77 cases /84%/. One result was false positive, 3-false negative. The value of immunocytochemical methods in differential diagnosis of poorly differentiated neoplasms was stressed.
