title: De novo papillary squamous carcinoma of the lacrimal sac.
abstract: We report a rare case of a papillary squamous carcinoma of the lacrimal sac diagnosed at first presentation. The initial presentation of the patient discussed here mimicked that of a lacrimal sac mucocele. This report highlights the clinicopathological characteristics of this tumour, as well as the multidisciplinary approach required in its management.
