We present a case of a second-born breastfed infant presenting with zinc deficiency whose mother was found to have a novel heterozygous mutation in SLC30A2. A previous baby did not have manifestations of zinc deficiency but the mother had taken a proton pump inhibitor during the second pregnancy.

Awareness of cutaneous manifestations of non-accidental injury (NAI) is essential for healthcare professionals working with children. Some cutaneous conditions may present with bruise-like lesions that can mimic NAI. We present the case of a male infant referred for investigation of NAI, who was subsequently diagnosed with cutaneous mastocytosis.
