Cutaneous rhinosporidiosis

Abstract

Rhinosporidiosis is a chronic granulomatous disease of the mucocutaneous tissue, which clinically presents as polypoidal growths. Cutaneous lesions are infrequent and are generally associated with mucosal lesions. We present a case of cutaneous rhinosporidiosis in association with recurrent nasopharyngeal rhinosporidiosis in a 65-year-old male patient. He presented with dysphagia for solid foods and skin growth on the left side of jaw of 2 years duration. Histopathology of cutaneous and nasopharyngeal lesions revealed numerous thick walled sporangia in a vascular connective tissue along with a granulomatous inflammation confirming the diagnosis of cutaneous and nasopharyngeal rhinosporidiosis. Endoscopic removal of nasopharyngeal polyp was done and he was started on dapsone therapy.

Cutaneous Rhinosporidiosis with varied clinical presentations in an Immunocompetent Adult

“…It is supposed to arrest the maturation of sporangia and accelerate degenerative changes by inducing stromal fibrosis. 9 Our patient had multiple cutaneous lesions -warty growths, subcutaneous nodules and tiny molluscum-like papules which could be curetted out. He had history of nasal polyp and the histopathology confirmed the diagnosis of rhinosporidiosis.…”

“…Four forms of the disease have been described-nasal, ocular, cutaneous and disseminated. 9 Nasopharyngeal rhinosporidiosis affects mainly males (70-90%) and usually presents with nasal obstruction and bleeding. They appear as pink friable polyps with strawberry-like dots on its surface, which are spores in the sporangia.…”

Primary cutaneous rhinosporidiosis: an unusual lesion with an unusual presentation

“…The most commonly involved site is the nasopharynx. Nasopharyngeal lesions present as pedunculated or sessile vascular polyps, which may extend into the nasal cavity 2. Other less common sites of infection are the eyes, aerodigestive tract and skin.…”

Rhinosporidiosis — a report of two cases

“…Dissemination to anatomically unrelated sites is mainly attributed to hematogenous spread [4]. Apart from these; a possibility of lymphatic spread has also been considered [5]. Involvement of tracheobronchial tree may be due to autoinoculation or hematogenous spread [6].…”

“…Spontaneous remission can rarely occur [5], however, treatment should be started at the earliest after the diagnosis. Diathermy excision is the treatments of choice [5]. Recurrences are still common.…”
