Rhinosporidiosis is a granulomatous disease that is a disease caused by Rhinosporidium seeberi. Though it occurs universally, the disease is widely prevalent in the tropics, especially in southern India and Sri Lanka. It usually affects the nasal mucosa and nasopharynx and rarely the conjunctiva, lacrimal sac, tonsils and skin. We present a case study of an isolated lacrimal sac rhinosporidiosis in a 15-year-old boy who was a resident of Terai. He presented with a diffuse left medial infraorbital swelling for a period of 14 months. He also complained of intermittent epiphora. External examination of the left eye revealed a diffuse, soft, and nontender swelling in the medial infraorbital region. Fine needle aspiration report was inconclusive. A computed tomography scan of the paranasal sinuses revealed an isodense lesion with mild enhancement within the preseptal compartment along the inferior aspect of the left orbit. A dacryocystectomy was performed and histopathology report confirmed rhinosporidiosis. There is no recurrence after 2 years of follow up.
