Rhinosporidiosis--a clinicopathological study of 34 cases.
Rhinosporidiosis was the commonest (68%) fungal lesion encountered during the period of 11 1/2 years from January 1987 to July 1998. Men in 2nd, 3rd, 4th decade were commonly affected. Nose and nasopharynx were the commonest (85%) sites involved followed by ocular tissue (9%). One patient had involvement of bone (tibia). Generally a lymphoplasmacytic response was observed in all cases. Polymorphonuclear leukocytic response mostly observed at the site of rupture of sporangia. Epithelioid cell granulomatous and giant cell response observed in 47% of cases. Transepithelial migration of sporangia observed in 76% of cases. Rhinosporidium seeberi could be easily identified in haematoxylin and eosin stained sections. The walls of young trophic forms are delineated well with the PAS stain and verhoeff van Gieson stain.
