Metastatic rhinosporidioma in a child.

Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi. It commonly affects nasal mucosa and conjunctiva. Subcutaneous disease is unusual and it is often mistaken for soft-tissue sarcoma. Such tumoral rhinosporidiosis has never been reported in children. This report describes, for the first time, an 11-year-old girl who presented with nasal polyp and multiple metastatic swellings of rhinosporidial origin. Fine-needle aspiration cytology and histopathology were diagnostic. Surgical excision, followed by dapsone therapy, was found to be useful.
