title: Penile Granuloma Annulare.
abstract: A 50-year-old man presented to the genitourinary medicine clinic with a 3-year history of skin-colored circular papules over the shaft and glans of the penis. There were multiple lesions that were initially small, around 0.3 cm in diameter, and gradually enlarged. Physical examination revealed five nodules over the glans and shaft of the penis, with the largest lesion measuring 3×1 cm over the lateral aspect of the shaft (Figure 1). There were no similar lesions elsewhere. There was no lymphadenopathy and the rest of the examination was unremarkable. The patient complained of discomfort during sexual intercourse but the lesions were otherwise asymptomatic and nontender. There was no history of trauma to the area and no dermatological history. He had had the same sexual partner for the past 22 years, no significant medical history, and was not taking any medication. He was a smoker with a 32-pack-year history. His family history did not include any dermatological diseases. His father was diagnosed with type II diabetes at 65 years of age and his mother had hypertension since age 60 years. He had consulted his general practitioner regarding the penile eruption a year earlier and was treated for a presumed fungal infection with clotrimazole cream for 1 month with no effect. Results from genitourinary investigations for sexually transmitted diseases including syphilis were all negative.
