[Carcinoma of the lacrimal sac].

Abstract

The present paper reports on the case of a 63 year-old woman twice operated for chronic suppurated dacryocystitis. At the third operation the lacrimal sac which was enlarged and rigid was removed. Section of the sac revealed a pinkish-grey formation that occupied the entire lumen of the sac. Histologic examination showed a poorly differentiated carcinoma with an islet-alveolar distribution. Stress is laid on the rare occurrence of primary malignant tumours of the lacrimal sac and the diagnostic difficulties in the onset period.
