Cutaneous Blastomycosis. Presented by Dr. Saul S. Robinson and Dr. Kendall Frost.
D. S., a Mexican laborer aged 32, worked in a slaughter house in 1919 and 1920. He underwent an operation for an anal fistula in 1928. The same year he noticed the lesion on the right buttock. The growth of the lesion has been gradual. There is an elevated pear-shaped, irregular, lobulated mass on the inner aspect of the right buttock. A complete medical examination showed no evidence of systemic involvement. Smears showed blastomycetes, including double-contoured and budding forms. Cultures on Sabouraud's medium and on dextrose agar gave negative results. Roentenograms of the osseous system showed no abnormalities; those of the chest showed fibrosis of the apex of the right lung. The Wassermann reaction of the blood was negative on Aug. 1, 1935. Material for a biopsy was obtained, but the slide is not ready.
