MYCETOMA


Mycetomas are chronic pyogranulomatous actinomycotic or mycotic infections of the skin and deeper tissues which form firm, often large and multiple masses, possibly with discharging sinuses.

Various oral or soil organisms such as Actinomyces, Nocardia and Streptomyces spp may be involved in actinomycotic mycetomas.

Mycotic mycetomas are rare in cats and dogs but there are reports of cases involving Torula spp and Microsporum canis.

Therapy includes radical surgical resection and antibiotic (see page 128) or antifungal therapy (ketoconazole at 5-10 mg/kg orally three times daily or griseofulvin at 15-30 mg/kg orally daily) but is often unsuccessful.
