Lymphomatoid Papulosis (LyP) is a rare skin disorder characterized by chronic, recurrent papules and nodules that heal spontaneously. This report discusses an 8-year-old Filipino female with a three-month history of erythematous pruritic papules evolving into plaques. A skin biopsy confirmed CD30-negative LyP, and treatment with Methotrexate resulted in significant improvement of the lesions. This case illustrates the complex diagnostic and therapeutic journey of LyP in children, emphasizing the importance of careful clinicopathologic correlation and the challenges of management due to the lack of curative therapy and the risk of malignant transformation.
