A persistent submammary rash A 70-year-old woman presents with a submammary rash that has been present for a number of weeks. What has triggered this persistent eruption? Case presentation A 70-year-old girl presents with a persistent, uncomfortable and slightly eroded submammary rash that has been present for a number of weeks . She complains of a burning feeling in the rash. The rash offers been treated with a potent topical corticosteroid, without improvement. A epidermis culture and scraping have not shown evidence of a fungal infection. She is afebrile, and blood tests show a normal white cell count.Radioiodine use is raising in the United States, with concern over who should receive it, particularly among individuals with low-risk tumors.40 Therefore, reducing the radiation exposure is a significant step forward. The question about whether radioiodine ablation can be safely avoided in low-risk patients is currently being tackled in a randomized trial in the United Kingdom .41.. Corinne S.
