Abstract
Ocular rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi, a protistal microorganism endemic in the hot, tropical climes of India and Sri Lanka. It often presents as a friable, vascular conjunctival polyp but may mimic other ocular conditions. We present the case of a 35 year old female with an ocular polypoid mass that resembled a conjunctival hemangioma but was proved to be Ocular rhinosporidiosis on histopathology. Thick walled sporangia of Rhinosporidium seeberi containing multiple nucleated endospores are the typical diagnostic features on histopathology. Total wide-base excision of the polyp, preferably by electro-cautery, is recommended to prevent spillage of endospores and recurrence of the lesion. This is the first reported case of ocular rhinosporidiosis from Jammu & Kashmir state of North India.References
