Macular Arteritis

We report two pediatric cases of macular arteritis presenting as asymptomatic retiform pigmented macules on the legs. Biopsy showed deep dermal-subcutaneous lymphocytic arteritis with fibrin deposition and luminal narrowing, with a negative infectious and autoimmune workup. Both patients remained well with stable lesions at 1 and 7 years of follow-up. These cases add to the limited pediatric literature and support macular arteritis as an infrequent benign cutaneous arteritis, helping avoid unnecessary investigations and aggressive treatment.
