Abstract
Rhinosporidial lesions in the skin are pathogenetically classified as primary, secondary and as components of disseminated disease. Estimates of the incidence of rhinosporidiosis in various sites vary between 1 and 8% of all cases of rhinosporidiosis. The disease is mainly of occupational origin after exposure to ground waters and is noncontagious and noninfectious. Cutaneous rhinosporidial lesions are diverse in morphologies, and definitive diagnosis is provided by skin-histopathology with the conventional H&E stain, while discharges are diagnosed by cytology using the periodic acid-Schiff stain. Surgery is the treatment of choice on accessible sites with single or a few nodules, supplemented with drugs, notably dapsone; multiple extensive sessile growths, when surgery is difficult, will need drug therapy. Surface application of biocides is ineffective.
