Disseminated cutaneous rhinosporidiosis: varied morphological appearances on the skin.

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.

Polymorphic ecthymatoid dermosporidiosis.

We report the case of a young Chhattisgarhi male with polymorphic dermosporidiosis (cutaneous rhinosporidiosis). He had multiple subcutaneous nodules and an ecthymatoid skin lesion along with nasal rhinosporidiosis. The diagnosis was confirmed by demonstration of sporangia with endospores in fine-needle aspiration cytology (FNAC), histopathology, and imprint smear from the skin lesions. Treatment was by surgical excision, electrocoagulation, and dapsone. There was no recurrence. Dermatologists should be aware of the diverse cutaneous manifestations of this primarily nasal disease. This is the second published report of polymorphic dermosporidiosis, and the first one reporting an ecthymatoid lesion.

Disseminated cutaneous rhinosporidiomas in an immunocompetent male.

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.

Disseminated cutaneous rhinosporidiosis.

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.

Light and electron microscopic findings in rhinosporidiosis after dapsone therapy.

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.

[Craniofacial granulomatous lesions]. / Processus granulomateux cranio-faciaux.

Granulomatous lesions of the cranio-facial area are frequent and various in their nature: lymphohistiocytic with or without eosinophils, tuberculoid-like with epithelioid and giant cells, or sometimes made essentially of giant cells. Their etiology can be known or easy to find: foreign body granuloma, sarcoidosis, leprosy, rhinoscleroma, fungal diseases especially zygomycosis and rhinosporidiosis, parasitic diseases. The lethal midline granuloma is a clinical entity characterized by its necrotic and relentlessly progressive destructive presentation. After elimination of a malignant process, especially lymphoid, and of a Wegener's granulomatosis the diagnosis will be "idiopathic midline non-healing granuloma". Some of them will stay located at the facial area; others will disseminate as a malignant disease. Central giant cell granuloma and histiocytosis X, especially eosinophilic granuloma, are two other varieties of granuloma, different of the former granulomatous infiltrates by their clinical presentation and their evolution.

Disseminated cutaneous rhinosporidiosis treated with dapsone.

A case of disseminated cutaneous rhinosporidiosis is reported. The possibility of leprosy was excluded. Dapsone was found very effective in curing the cutaneous nodules. Though many chemotherapeutic agents have been tried both topically and internally, so far surgery is considered to be the effective method of treatment. Our experience with this case suggest that Dapsone may be a successful drug in cutaneous rhinosporidiosis.
