CASE 2

A 50-year-old man presents with a red bump on his right hand. It has been present for several months. The lesion started as a wart, which he unsuccessfully attempted to treat with salicylic acid. Approximately 1 month ago, the patient attempted cutting the lesion off. Since then, a red bump, which bleeds easily with minor trauma, has appeared in the same area. The patient has no other medical problems and takes no medications. Upon physical examination, a red, friable papule with a peripheral collarette of scale is observed on the right palm.
