title: Rhinosporidiosis of lacrimal sac: An interesting case of orbital swelling.
abstract: Rhinosporidiosis is a chronic localized granulomatous disease caused by Rhinosporidium seeberi, an aquatic protistan parasite belonging to a clade, Mesomycetozoea. Infestation of Rhinosporidiosis to the eye and adnexa is termed oculosporidiosis, in such cases, conjunctival mucosa is mostly involved; however in our case, it involved only the lacrimal sac and deeper periorbital tissue and presented as a case of orbital swelling. Surgical excision of the lesion was done, postoperatively dapsone therapy was given for 6 months, and the patient responded very well with no recurrence till date.
