ABSTRACT
Rhinosporidiosis is a chronic recurrent infective granulomatous disease of man and animals. It is endemic in India and Sri Lanka. Rhinosporidiosis is a chronic disease commonly involving the nose and nasopharynx. Cutaneous lesions, although rare, can occur due to autoinoculation or due to hematogenous spread. However, disseminated cutaneous lesions presenting as tumor-like swellings are rare. We report here a 48-year-old immunocompetent patient who had disseminated painless cutaneous tumor-like swellings over both the upper limbs, abdomen, left buttock and calf since 10 months, gradually increasing in size. On inquiring, the patient gave history of excisions and electrocauterization of subglottic and nasal polyps. Histopathological examination of these lesions was suggestive of rhinosporidiosis. The general and systemic examinations of the patient did not reveal any abnormality.

Se evidencia la presencia de promastigotos metacíclicos de Leishmania pifanoi en el conducto hipofaríngeo de Lutzomyia youngi infectados experimentalmente por ingurgitación sobre lesiones tarsales de hámsteres. La aparición de metacíclicos en la hipofaringe, cuya morfología se ilustra, ocurre entre los 5 y 9 días de desarrollo postprandial y es más frecuente en insectos alimentados com sacarose comercial no refinada. Se investiga el papel de derivados aminados de glucosa y galactosa y también de aminoácidos, en la promoción y migración de los metacíclicos
