A3-year-old boy presented to the Hospital for Sick Children with systemic symptoms and oropharyngeal and peripheral extremity changes suggestive of Kawasaki disease. He was found to have severe hypertension. ⋯ Toxins were considered when the patient's 20-month-old brother presented with similar symptoms, and the boys were subsequently diagnosed with elemental mercury poisoning. We review the literature on mercury intoxication and discuss the historical context, clinical syndrome (acrodynia), treatment, and radiologic findings of this unusual diagnosis.

Case ReportsAcetaminophen-induced toxic epidermal necrolysis in a child.
Toxic epidermal necrolysis (TEN) is a severe, life-threatening disorder that usually affects adults. It is often drug induced. ⋯ A lymphocyte stimulation test could not identify the culprit drug. Treatment with intravenous immunoglobulin seemed to halt the disease progression.

To analyze the clinical features, response to treatment, and follow-up of lichen striatus and any associated symptoms or disease, we designed a retrospective study involving 115 affected children at the Pediatric Dermatology Unit of the Department of Dermatology of the University of Bologna, Bologna, Italy. Between January 1989 and January 2000 we diagnosed lichen striatus in 37 boys and 78 girls (mean age 4 years 5 months). We studied their family history and the season of onset, morphology, distribution, extent, duration, histopathology, and treatment of their lichen striatus. ⋯ The confirmed association with atopy observed in our patients may be a predisposing factor. It has generally been accepted that lichen striatus follows the lines of Blaschko, and this distribution is a sign of both a topographic and a pathogenetic concept. In patients where lichen striatus is along axial lines, a locus minoris resistentiae, we suppose that this distribution may only be an illusory phenomenon in instances in which the trigger factor prefers this route, consisting of several successive Blaschko lines, but appearing as a single band.
