REPORT OF A CASE
A 32-year-old Hispanic man presented with a draining plaque on the sole
of his right foot. He first noted the lesion 5 years ago as a small pustule,
believed to be an insect bite. The affected area gradually extended to involve
the plantar and lateral aspects of the foot as papulonodular lesions developed
and periodically drained purulent material. The patient was otherwise healthy
and denied constitutional symptoms of infection.
Physical examination revealed induration of the right foot, with a draining
plaque extending along the ventral and lateral surfaces. Numerous crusts marked
healing sites of drainage (Figure 1). Biopsy of the lesion produced purulent exudate and discharge of a firm yellow
granule, approximately 2 mm in diameter. The tissue was sent for culture and
histologic examination (Figure 2). Radiologic examination showed no bony involvement.
