Radiation-induced morphea (RIM) is a rare but recognized late complication of radiotherapy. It was first described in 1905, not long after the initial discovery of X-rays by Roentgen. Characterized by the deposition of excess collagen in the dermis, it results in thickening of the skin.

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 7-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 develop due to 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. Generalised eruptive naevi with subsequent development of dysplastic naevi and melanoma in situ have been reported following chemotherapy, highlighting the importance of continued clinical observation.

Panton-Valentine leukocidin (PVL)-producing Staphylococcus aureus results in leukocyte destruction and tissue necrosis (Pediatric Dermatology 2007;24:401). It can be associated with a spectrum of clinical manifestations that range from localized staphylococcal skin infections to sometimes severe necrotizing pneumonia (Clin Infect Dis 1999;29:1128). We report a case of four siblings, three brothers whose atopic dermatitis was complicated by cutaneous lesions and furunculosis, while their 21-month-old sister had a fatal PVL positive staphylococcal pneumonia.

Azathioprine is a valuable agent in the treatment of severe childhood atopic eczema. Thiopurine methyl transferase (TPMT) exhibits autosomal codominant polymorphism and plays an important role in the metabolism of azathioprine. In most large population groups studied to date, approximately 10% of the population had intermediate activity due to heterozygosity at the TPMT locus, and about 0.
