Complete resolution of primary cutaneous marginal zone B‐cell lymphoma on the cheek of a 7‐year‐old boy with intralesional triamcinolone and tincture of time

Abstract A 7‐year‐old healthy boy presented with an asymptomatic smooth, firm red plaque on the cheek. Histopathology, immunostaining, molecular testing and imaging confirmed a diagnosis of a primary cutaneous marginal zone B‐cell lymphoma. The lesion was treated with intralesional triamcinolone, with complete clinical resolution achieved within one year. Intralesional steroid injection is an effective first‐line modality for the treatment of patients with limited disease in cosmetically sensitive areas.
