DR JULIA O'MAHONY ORCID 0009-0004-0458-934X DR CATHAL O'CONNOR ORCID 0000-0001-7084-5293 Case Report

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.

Porokeratotic adnexal ostial nevus (PAON) is a term encompassing porokeratotic eccrine ostial and dermal duct naevus (PEODDN) and porokeratotic eccrine and hair follicle naevus (PEHFN). We present the case of a seven-year-old girl who presented with hyperkeratotic verrucous papules in a blaschkolinear distribution on the sole of her left foot.

Lentigines are brown macules which represent increased proliferation of melanocytes at the dermo-epidermal junction. We report three cases of acral lentiginosis in children following chemotherapy for acute lymphoblastic leukaemia (ALL) which have persisted following cessation of chemotherapy, despite avid photoprotection.
