Read Case Claim CME

A woman in her 70s presented for evaluation of intensely pruritic lesions on her anterior trunk. The lesions first began 1 year before presentation and were gradually increasing in size. She was initially treated by her primary care clinician with selenium sulfide, topical terbinafine, and hydroxyzine for a presumed fungal infection, but the lesions did not improve and her pruritus remained. She denied other symptoms. The patient had a remote history of infiltrating ductal breast carcinoma, which was diagnosed in 2007. At that time, she was treated with a bilateral mastectomy and a course of tamoxifen, but she was lost to follow-up.
