RESUMEN
Rhinosporidiosis is a chronic granulomatous disorder caused by Rhinosporidium seeberi . It frequently involves the nasopharynx and occasionally affects the skin. We report a case of 45-year-old man who had disseminated cutaneous rhinosporidiosis with cutaneous pseudohorn, its base arising from rhinosporidiosis. The case presented with multiple reddish lesions over the nose of six years duration. In the past year, he developed skin lesions over the left arm, forearm, back, and chest. On examination, polymorphic lesions of rhinosporidiosis in form of verrucous plaque, unulcerated tumor, granulomatous growth, and furunculoid lesions were observed. Interestingly, there was a cutaneous horn over the chest which on histopathological examination showed hyperplastic epithelium with numerous globular cysts of varying shape, representing sporangia in different stages of development and transelimination. Computerized tomography scan of the chest showed bilateral opacities suggestive of lung involvement. On the basis of these clinical and histopathological findings, a diagnosis of nasal rhinosporidiosis with cutaneous and systemic dissemination was made.

A 48-year-old male patient presented to Skin and VD outpatient with multiple granulomatous growths of different sizes all over the body, including numerous subcutaneous swellings mimicking lipomas of 2 years duration. Two and half years back he was operated for a polypoidal growth of left nostril with subsequent recurrence. Fine needle aspiration cytology and histopathology of the cutaneous lesion confirmed the diagnosis as rhinosporidiosis. We report this rare case of disseminated cutaneous rhinosporidiosis.

Morphological findings in serial nasal mucosal biopsies from three cases of rhinosporidiosis on dapsone therapy were compared with biopsies from 33 patients taken before dapsone or surgical treatment was initiated. All biopsies were examined by light microscopy and five by electron microscopy. Counts of histologically intact and degenerated organisms showed a decreasing proportion of intact forms with treatment.
