Chromomycosis in Rhinella icterica

The integuments of five toads (Rhinella icterica) were histologically analyzed and two of them exhibited brownish encapsulated subcutaneous mass of the integument. Fungal elements involved by multinucleated histiocytic giant cells were restrict to the hypodermis. This granulomatous inflammatory process showed an extracellular matrix rich in a hyaluronic acid. Moreover, these areas were surrounded by fibrous connective tissue, where collagenous fibers predominate. Since chromomycosis was previously reported in a bufonid from Amazon region and this work was first in Southeast from Brazil, it is possible that this disease may be spread to other Brazilian regions.
