She indicates that she did not start having problems until she was 5 years of age, after which her skin has progressively become drier and scalier. She has tried all types of over-the-counter moisturizers with no resolution. What is the most likely diagnosis?? A: Ichthyosis vulgaris, B: Atopic dermatitis, C: Psoriasis, D: Miliaria, E: Suborrheic dermatitis,  <response>: Based on the description of dry, scaling skin that started at age 5 and has progressively worsened, the most likely diagnosis is ichthyosis vulgaris. Ichthyosis vulgaris typically presents in childhood with dry, scaly skin that worsens over time. The other options can present with scaling but do not fit the timeline or description as well. Atopic dermatitis and psoriasis often have an earlier childhood onset. Miliaria is unlikely in the absence of mention of sweat duct obstruction. Seborrheic dermatitis would cause scaling in more localized areas like the scalp and face rather than generalized scaling.A: Ichthyosis vulgaris
