RHINOSPORIDIOSIS AND SARCOSPORIDIOSIS 



tissue is studded with pin-head sized whito dots which represent the 

 cysts. 



As can be judged from Fig. 708, the mucous membrane is thrown 

 into folds which form papillomatous-hke processes, in which, here 

 and there, the epithehum is thin or wantrng. The subepitheUal 

 tissue is very vascular, and is infiltrated with polymorphonuclear 

 leucocytes, and shows small haemorrhages at times, and in the nose 

 may also be myxomatous in places. The cysts may be seen tying 

 in this tissue or bulging through the epithelium {vide 2 in Fig. 708 

 and also in Fig. 709, which shows a cyst full of pansporoblasts, which 

 appear under higher magnification in Fig. 710).

Pathology. — ^The parasite spreads in the body by the rupture of 

 the cyst and the liberation of the spores. We suspect that it may, 

 at times, give rise to a condition resembling a septicaemia. 



Symptomatology.— The patient has his attention drawn to his 

 nose by profuse bleedings, and in a little time notices a growth. 

 On examination this is found to be a small vascular pedunculated 

 tumour, about the size and shape of a pea, freely movable and 

 painless, attached to the anterior and upper part of the cartilaginous 

 septum. In appearance it resembles a strawberry or a raspberry. 



It may, however, form polypi in other regions, as, for example, 

 on the conjunctiva, or papillomata on cutaneous surfaces, as, for 

 example, on the penis.
