Cat pythiosis: tumoral-like mass caused by Pythium insidiosum.
Cutaneous dog pythiosisAtypical case of equine pythiosis. The infection began in the lower extremity and spread, trough lymphatic vessels, to the horse's chest.
Typical cutaneous pythiosis in an equine. Small white masses, known as "kunkers", are observed in the center of the lesion.
Kunkers or leeches:
Granulomatous coagula consist of necrotic Mc, Eoand hyphae
Horse pythiosis with bone involvement (from a chronic case of the disease).
• "Kunkers" removed from the above case. These masses containe viable hyphae of P. insidiosum.
