Intraocular tumors. A cytopathologic study.
The cytologic characteristics and histopathologic correlates of common ocular tumors were examined using (1) cytologic and histologic specimens prepared from enucleated eyes with retinoblastoma and melanoma, (2) cytologic specimens prepared from clinically obtained intraocular fluids from eyes with lymphoma, metastatic adenocarcinoma and retinoblastoma and (3) cytologic specimens prepared from orbital aspirates and cerebrospinal fluids from a patient in whom retinoblastoma had spread to the orbit and central nervous system. Retinoblastoma cells occurred singly and in clusters and were associated with abundant necrotic debris and portions of capillaries with perivascular tumor infiltrates. Melanoma cells frequently had prominent nucleoli and variable amounts of fine cytoplasmic pigmentation and were found individually and in groups. Lymphoma cells were noncohesive, with scant cytoplasm. Metastatic intraocular adenocarcinoma cells had well-defined borders, multiple nucleoli and vacuolated cytoplasm. In general, the cellular morphology in the cytologic and tissue preparations of the intraocular tumors correlated well with each other. The findings suggest that common primary and metastatic intraocular tumors can be differentiated in cytologic preparations.
