[Tear-sac concretions (author's transl)].

Report is given on three cases of dacryolithiasis. All cases were demonstrated by dacryocystography. Two dacryoliths were obtained at operation, another one by spontaneous passage through the nose. Histopathological examination of the dacryoliths in two cases revealed the presence of a mycotic infection, most likely with Candida albicans. The casts were found to be composed of layers of neutral and acid mucoproteids and lipids, accompanied by an infiltration with leucocytes.
