ABSTRACT
Lamotrigine is one of the most prescribed antiepileptics in children and a well-known cause of drug-induced liver injury (DILI). The typical presentation usually includes a drug rash with eosinophilia and systemic symptoms (DRESS syndrome). Cases are typically mild and self-limiting, requiring supportive care only. We report a severe Lamotrigine-induced DILI with a non-typical presentation with hyperammonaemia and rapid clinical deterioration. We present a literature review exploring contributing factors, transplant considerations and liver histology. Histology showed periportal necrosis, which is recognised as a pattern of DILI but has not been previously described with Lamotrigine. Our patient proceeded to transplant and is the first reported liver transplant for Lamotrigine DILI in a child. A directed and rapid diagnostic approach is crucial to avoid delays and rule out multisystemic metabolic and genetic conditions that preclude liver transplantation.

ABSTRACT: Inflammatory myofibroblastic tumours (IMTs) are rare soft tissue tumours. Reports of gastrointestinal tract, liver and pancreas tumours are limited. The objective of this study is to identify presenting features, contributing prognostic / etiological factors and any variability in outcomes in the context of different historical treatments. We retrospectively reviewed the records of seven children treated at our hospital between 2006 and 2019 and assessed the demographic, presentation, treatment, immunohistochemistry, and outcomes of their tumours. Age range at presentation was 4âmonths-15âyears with a male predominance. Presentations were typically due to local mass effect or incidental discovery. Systemic symptoms were rare. Outcomes were good with six out of seven stable or in remission irrespective of treatment. Surgical resection where possible is the treatment of choice. Medical therapy had good outcomes with chemotherapy acting as first line treatment when required. The only negative prognostic factor identified was local spread at the time of presentation.
