Mixed Papilloma of the Lacrimal Sac as a Cause of Hemolacria.

Abstract

Inverted papillomas (IPs) derived from the lacrimal sac are a rare pathology, with only seven cases reported in the literature.^{1,2 "}Mixed" endophytic and exophytic papillomas of the lacrimal sac are even more rare, with no reports in the literature. We present the case of a 55-year-old man who presented to the clinic with unilateral hemolacria. Multiple imaging modalities revealed a mass in the lacrimal sac, which was subsequently surgically excised by an otolaryngologist and oculoplastic surgeon. Pathologic analysis of the specimen demonstrated both exophytic and endophytic growth patterns, suggestive of a mixed papilloma subtype. This case highlights the importance of prompt, accurate diagnosis and interdisciplinary management, as patients require regular clinical follow-up to monitor recurrence and malignant transformation.
