Jatropha Curcas poisoning is a fairly common occurrence in Indian population [1,2]. It follows ingestion of the plant’s nuts. It generally manifests with complaints of vomiting, abdominal pain and diarrhea [3]. These are attributed to the Toxalbumin, Curcin and cyanic acid found in these nuts. Though it generally presents with symptoms of mild gastroenteritis, it may sometimes be severe enough to cause hypovolemic shock. We came across an 8 year old child who presented with these symptoms following consumption of the Jatropha Curcas nuts. She also presented with newly developed purpuric spots over whole of the body (Fig. 1). They were especially prominent over the knees. Her blood work-up did not reveal any other cause of the purpurae. There were no signs of vasculitis either. She was managed conservatively with fluid resuscitation. The purpuric spots resolved over 3 weeks. We conclude that, though poisonong following Jatropha Curcas results in gastroenteritis, it can also result in purpuric spots. This is the first known dermatologic manifestation and may be misinterpreted by the unwary physician.
