A 29-year-old renal transplant patient taking mycophenolate mofetil 1 g b.i.d., cyclosporine 100 mg b.i.d. and prednisone 10 mg q.d. presented with white paint, dot-like incrustations on the skin of his right scrotum. A 10% potassium hydroxide preparation of scrapings from the lesions showed septate hyphae and Microsporum gypseum was cultured. Topical bifonazole 1% cream cleared the lesions within 2 weeks. At the 2-month follow up there was no relapse.
