Rhiinosporidiosis - unusual presentations.

Rhinosporidiosis is an infection caused by Rhinosporidium seeberi that frequently presents as polypoidal nasal lesions. Here, we report two cases of rhinosporidiosis with unusual presentations. The first case presented in our department with chronic dacryocystitis of left side for endoscopic dacryocystorhinostomy (endoscopic DCR) operation. The second case presented as a long hanging mass arising from the right side of nasal septum. The diagnosis was established on the morphological basis by the identification of endospores and sporangia. The clinicopathological and immunologic features were discussed and the literature was reviewed.
