Circumferential Acute Limited Exanthematous Pustulosis

In the document from September 1, 2018, a case of circumferential acute limited exanthematous pustulosis (ALEP) in a 16-year-old African-American woman is described. She presented with a 2-week history of pruritic and painful small pustules around her hairline, which increased in size and number, accompanied by a nonproductive cough. The differential diagnosis included contact dermatitis, pustular psoriasis, and ALEP. A biopsy confirmed the diagnosis of ALEP, which is typically drug-induced but in this case was suspected to be triggered by an infection. The patient was treated with topical steroids, resulting in improvement. The document also includes a case of circumscribed juvenile pityriasis rubra pilaris in a 5-year-old girl, who was successfully treated with topical keratolytic and steroid, avoiding the side effects of the first-line therapy acitretin. Additionally, a case of classic Sweet syndrome in a 54-year-old man is presented, which was resolved with systemic corticosteroids. Lastly, a case of clear cell variant of eccrine porocarcinoma on the hand of a 90-year-old woman is reported, which was treated with surgical excision. No commercial support was identified for any of the cases.
