2-year old domestic short hair presents for chronic severe skin lesions. The lesions
consist of draining nodules and erythematous plaques. Therapies with prednisone and
antibiotics have resulted in improvement of the lesions; however, the lesions have never
fully resolved. The owner describes that the lesions originally started out on the right
front paw and have progressed. You perform cytology from the drainage of the lesions
and find numerous cigar-shaped organisms in macrophages. You ask if any wound was
noted on the animal, and the owner explains that she pulled what looked like a splinter
from the right front paw before the lesions started. What is the diagnosis and treatment
for this disease? -
\Sporotrichosis; Itraconazole
