A 42-year-old white man presented with a 6-month history of several pruritic, slow-growing lesions on the glans. His medical history was unremarkable, with no previous history of trauma or unprotected sexual intercourse recorded. Physical examination revealed three small, yellowish-white papules on the anterior left side of the glans (Fig. 1). A thorough dermatological examination did not show other lesions on the skin or other mucous membranes. Laboratory investigations disclosed high levels of uric acid and glucose (8.8 mg/dL and 138 mg/dL, respectively; normal ranges 1–7.0 mg/dL and 100–125 mg/dL, respectively), with no other remarkable findings (complete blood cell count, renal and liver function tests). The patient denied prior episodes of gouty arthritis. What is your diagnosis?
