Pruritic subcutaneous nodules of the upper arm in a 2‐year‐old child

Abstract

A 2-year-old-girl presented with a 6-month history of a pruritic eruption on the lateral left upper arm. On examination, there were palpable subcutaneous nodules, with overlying excoriations, hypertrichosis, and hyperpigmentation (Figure 1). Her mother reported that she had previously undertaken an ultrasound (not available for review), that was suggestive of an "angioma." The patient was otherwise healthy, had no regular medications, no known allergies and was up to date on recommended vaccinations.
