title: Pyogenic granuloma of the lacrimal sac.
abstract: In this report, we describe three adult patients diagnosed with lacrimal sac pyogenic granuloma. The presenting symptoms were acute dacryocystitis, lacrimal mass, and bloody tears. The nasolacrimal drainage pathway was obstructed in all cases. Radiologic evaluation performed in one patient revealed the presence of a well-defined mass in the sac with homogenous contrast uptake. Histopathologic examination revealed capillary proliferation and inflammatory cells in a fibromyxoid stroma. The patients were followed up for 11-23 months after external dacryocystorhinostomy without recurrence of the tumor or nasolacrimal obstruction. Pyogenic granuloma may develop from the lacrimal sac mucosa and may cause bloody epiphora. Such a tumor is visualized as a hemorrhagic mass lesion, and it may not have a negative effect on the outcome of DCR.
