| Abstract|| |
Rhinosporidiosis is a chronic granulomatous condition caused by the pathogen Rhinosporidium seeberi which frequently involves the nasopharynx and occasionally affects the skin. The disease has been reported from across the globe but the highest incidence has been from south India and Sri Lanka. This disease is commonly seen in adult men and the possible mode of transmission to humans is thought to be by direct contact with spores through dust, infected clothing, fingers, and swimming in stagnant water. The classical presentation is mucosal and here we present a case which presented as a growth on the chest wall. And we stress the need to keep a high index of suspicion in such cases in endemic areas

| Case Report|| |
A 55-year-old man presented with a mildly painful red lesion on the right side of his chest that was gradually progressive in size over the past 2 months. He had pain at the site due to pressure effect especially when he tried to lie in prone position, which was the reason for seeking medical attention. He was not a diabetic, but was on antiplatelet medications since many years for his cardiac illness. He did not give history of any other constitutional illness except a surgery about a year back, records of which were not available. He did not give any history of bathing in ponds or rivers in the past. The routine blood investigations, chest X-ray, and HIV screening were negative.
We did not find anything abnormal in his general physical examination. Dermatological examination showed an erythematous nodule with a size of about 4 × 3 × 2 cm occupying the right side of his chest in the supramammary area [Figure 1] and [Figure 2]. It was slightly tender to touch and friable in consistency. The lesion did not bleed on touch, was immobile and well attached to the underlying skin. There was no regional lymphadenopathy. The lesion was excised in toto and skin closed with a flap in layers. The tissue on histopathology examinations showed thick-walled sporangia with numerous spores which was pathognomonic of the diagnosis [Figure 3] and [Figure 4].

| Discussion|| |
Rhinosporidiosis is a chronic granulomatous condition caused by the pathogen Rhinosporidium seeberi. It frequently involves the nasopharynx and occasionally affects the skin. The disease has been reported from about 70 countries with diverse geographical features, although the highest incidence has been from south India and Sri Lanka. This disease is commonly seen in adult men and the possible mode of transmission to humans is thought to be by direct contact with spores through dust, infected clothing, fingers, and swimming in stagnant water. ,,
The classical presentation of the disease is as pedunculated and sessile polypoid lesions on the mucosa of nose, eyes, and larynx; and very rarely on other parts of the body like skin, viscera, and brain. There are mainly three types of lesions that appear on the skin. They are: (1) Satellite lesions around the nose in case of nasal rhinosporidiosis, (2) generalized skin involvement with or without nasal involvement due to hematogenous dissemination, and (3) primary cutaneous type which may occur by direct inoculation of the organism into the skin.  Subcutaneous lesions though rare have also been reported. There are primarily three modes of spreads of the lesions viz. autoinoculation, hematogenous, and direct inoculation.  Definitive diagnosis of the disease is by histopathology of the excised specimen.  However, in the absence of facilities for tissue diagnosis, a simple aspiration cytology and examination of aspirated material under 10% KOH or Papanicolaou smear may be sufficient to find the organism in various stages of maturation.  Surgical removal and/or electrodessication remain the gold standard in the treatment of cutaneous rhinosporidiosis.  Dapsone is the only drug found to be beneficial in some cases which may act by arresting the maturation of sporangia and accelerating the degenerative changes in them. 
We report this case for its rarity of occurrence in this anatomical location and also to stress the need to keep a high index of suspicion when patients present with such lesions in an endemic geographic location such as southern India, even in the absence of mucosal lesions or high risk activity such as swimming in stagnant water, ponds, etc.
