The incidence of cutaneous torulosis, both in the United States and in Europe, has not as yet reached a point alarming to the physician and the layman. This disease is rare—at least its occurrence has rarely been reported in the literature—and needs closer attention than has heretofore been paid to it with regard to differential diagnosis. The infection usually manifests itself on the skin, as pointed out by Wile,1 in the form of acneform pustules, granuloma-like ulcers, deep-seated abscesses and nodules, the last-mentioned lesions varying in size and showing no tendency to ulceration.
Clinically the condition is worthy of a great deal of investigation, chiefly because it may simulate closely the lesions of blastomycosis and coccidioidal granuloma, particularly the European blastomycosis of Busse and Buschke. The correct differential diagnosis of these conflicting infections depends usually on the determination of the invading organism by the methods described by Weidman.
