Lymphoplasmocytic plaque in children (LPC) is a rare and distinctive skin disorder primarily affecting the pediatric population. Characterized by its unique histopathological features, the condition manifests as well-defined plaques with a predominance of lymphocytes and plasma cells infiltrating the dermis. Despite its limited prevalence, recognizing this entity is crucial for accurate diagnosis and appropriate management of affected patients. We report the case of a 10-year-old male presenting with LPC in the extensor surface of the upper arm, a rarely reported location, treated with both topical and intralesional corticosteroids resulting in partial improvement.
