813 An Erythematous-squamous Lesion of the Foot: A Quiz Stefano VERALDI, Paolo PONTINI and Gianluca NAZZARO Department of Pathophysiology and Transplantation, Università degli Studi di Milano, IRCCS Foundation, Cà Granda Ospedale Maggiore Poli­ clinico, Milan, Italy. E-mail: [email protected] A 23-year-old Caucasian man presented with an inflam- matory lesion on his right foot. The patient reported that he was in good general health and not on any systemic drug therapy. The lesion had appeared one week earlier accompanied by mild pruritus. No treatment was given prior to our examination. The latter showed an oval, 3×2 cm lesion on the medial surface of the right foot. The lesion was characterized by fine desquamation in the centre and well-defined, erythematous-papular borders (Fig. 1). No similar lesions were observed elsewhere. A clinical diagnosis of tinea was made. However, myco- logical examinations were negative. Bacteriological exami- nations were also negative. All laboratory tests, including tests for syphilis, were negative or within normal ranges. A biopsy was suggested, but was refused by the patient due to his work as a footballer. He was discharged without therapy. One week later, the patient returned due to development of an erythematous-papular, mildly pruritic rash on his trunk, upper limbs and thighs. What is your diagnosis? See next page for answer. Fig. 1. Erythematous-squamous lesion on the foot.
