A 5-month-old Malay boy presented with purpuric papules and plaques on the face and extremities accompanied by fever, coryzal symptoms and bilateral lower limb oedema. There were also bullous linear purpuric lesions on the right upper limb. Blood and culture tests were normal. Histopathological tests showed leucocytoclastic vasculitis, confirming the diagnosis of acute haemorrhagic oedema of infancy. The patient achieved complete recovery after 2 weeks with no recurrence.

The immature stages of necrophagous insects such as Diptera and Coleoptera play a vital ecological role in carrion decomposition. These invertebrates reduce the necromass significantly through consumption and recycle nutrients into organic forms which are readily being used by autotrophs or served as an abiotic storage in the soil ecosystem. Fly and beetle larvae are frequently encountered decomposers on ephemeral resource patches; however, lepidopterans associated with carrion decomposition is seldom reported. Here, we report colonization of Monopis sp. (Tineidae) and an unknown species of Psychidae on a rat carcass, and a Lithosiini caterpillar (Arctiidae) on a rabbit carcass in Peninsular Malaysia for the first time. The feeding behaviour and their potential forensic implications are discussed.
