Rhinosporidiosis is a rare
chronic granulomatous infectious disease caused by Rhinosporidium seeberi and it usually presents as a granulose
growth, most often in the nasal cavity or the area around the eye. This disease
can be transmitted by direct contact with spores through dust, infected
clothing and swimming in stagnant water. It is mainly endemic in India,
Srilanka, Bangladesh; and sporadic cases have been reported from United States
of America, Italy Brazil, Argentina and Africa.
Based on some literature research, it can be found that few cases of
nasal rhinosporidiosis have been reported in Nigeria. So in this paper, the
authors reported a rare case of nasal rhinosporidiosis in a 13-year-old male
patient from Sokoto, North Western Nigeria and aimed to caution
otorhinolaryngologists to have a high index of suspicion of this emerging
disease entity in the management of patient with nasal mass. The patient was presented
at the ENT clinic of Usmanu Danfodiyo University Teaching Hospital with
15-month history of intermittent epistaxis and left nasal mass noticed one
month before presenting. After entering in the hospital, he was examined
clinically and there was a strawberry like, fleshy polypoidal mass arising from
the septum on probing and filling the left nasal cavity with associated clear
mucoid rhinorrhea. Hematologic investigations showed the patient’s packed cell
volume to be 24% while the biochemical results were within normal limits. He
was also negative to HIV I and II screening. Plain radiographs of the paranasal
sinuses demonstrated a soft tissue shadow in the left nasal cavity but no bony
or sinus involvement. Histopathology of the specimen showed numerous sporangium
containing spores pathognomonic of rhinosporidiosis. Finally, the disease was
confirmed. Then the authors made a discussion on this disease.
In conclusion, rhinospridiosis is an unusual cause of nasal masses in
our region and is probably a fungal disease. To the best of our knowledge, this
is the first reported case in this region. This lesion largely mimics ordinary
nasal polyp; therefore, it is an important possible differential diagnosis to
be considered in our region when evaluating patients with nasal masses.
