REPORT OF A CASE
A 38-year-old man, a native of Somalia, presented to the dermatology clinic for examination of a slightly tender nodule on the dorsum of his foot (Fig 1). When the nodule was first noted 2 years previously, its diameter was 1 cm. The lesion changed little over the next 1½ years. Within the 6 months immediately before presentation, the mass steadily enlarged and became slightly painful. The patient gave no history of local trauma or any similar lesions elsewhere. He denied fever, chills, sweats, weight loss, cough, or lymphadenopathy.The patient's medical history was significant for progressive glomerulonephritis, which eventuated in renal transplantation several years before the lesion developed. As a result, he had been treated with prednisone, azathioprine, and cyclosporine.The nodule was excised intact and displayed a gross appearance reminiscent of an epidermoid cyst (Fig 2). Representative microscopic fields from the hematoxylin-eosin-stained sections are shown
