HISTORY:

A male in his 70s with a past medical history of, colitis, postoperative hypothyroidism, and aortic stenosis presents for evaluation of a scrotal lesion. Patient describes the lesion as a, “red spot,” that has been present for at least 5 years.

The lesion was asymptomatic until 1 year prior to presentation, when the lesion became pruritic. At that time he was treated with antifungal creams by his PCP. Subsequently the lesion was biopsied by dermatology. Based on the biopsy results, he was referred to OSU urology.

Physical exam reveals a left lateral anterior scrotal lesion that is scaly and erythematous (3cm x 2cm). Testes are bilaterally descended without masses or nodules. No groin lymphadenopathy.
