Exposure to Euphorbia lathyris latex resulting in alkaline chemical injury: a case report

IntroductionWe report the case of a patient with extreme pain following accidental exposure to the latex of Euphorbia lathyris.Case presentationA 76-year-old Caucasian woman attended the ophthalmology department with acute severe bilateral eye pain. This occurred immediately after having pulled a weed out of her garden with her bare hands. She recalled having subsequently rubbed her eyes. The offending plant, was brought into hospital and was identified as the Caper Spurge (Euphorbia lathyris). Her ocular pH was alkaline (pH 9). After copious irrigation, the pH normalised. She was treated with topical steroids, cycloplegics, lubricants and opioid oral analgesia. Three days later, she was symptom-free and her vision had returned to normal.ConclusionExposure to Caper spurge latex is a rare cause of keratoconjunctivitis. It can, however, potentially lead to corneal ulceration, anterior uveitis and rarely blindness. Treatment remains largely empirical. Exposure to the milky latex can result in extreme pain requiring prompt treatment. The use of goggles and gloves is recommended when handling this plant.

“…All the six species of the Araceae family [1][2][3][4] ; Dieffenbachia, Arisaema and Colocasia, Alocasia, Pinellia, and Phylodendron; reported previously to cause corneal crystals, are small ornamental plants, but in this case, our patient was hit by a tall tree, whose nature is obviously unknown to us; and could, but possibly does not belong to this family; as these are small ornamental plants, and not at all tall. We would have liked to identify the tree, but the injury occurred decades ago, in the dark night, and the patient could not identify or recall the type of tree at all, and also because of the severe symptoms caused by it, he was rushed to a hospital.…”

“…The other species 3,4 of plants known to cause crystalline keratopathy are Arisaema, Colocasia, Pinellia, Phylodendron, and Alocasia, although raphides are also found in other philodendron plants of the Araceae family, and may cause similar findings. 2 The more common cause of crystal deposition in the cornea is infectious crystalline keratopathy, first reported in 1983 by Gorovoy 5 et al in a corneal transplant, attributed to stromal colonization of gram-positive cocci along a suture tract.…”

This is a peculiar case of localized, silvery, iridescent crystal deposition in the cornea and lens, discovered twenty seven years after injury with an overhanging tree branch with sap exposure. The corneal tear at the time of injury was self sealing and there was also associated lens trauma, both managed conservatively on an inpatient basis, and leading subsequently to a corneal scar and localized cortical cataract, respectively, both demonstrating fine, silver, interspersed crystals. This is the first case to be reported in the world, of corneal crystal deposition in conjunction with lenticular crystals as a result of a tree branch injury.

“…Ocular exposure may produce chemical conjunctivitis, and even corneal abrasion. 8 Treatment is mainly symptomatic relief. Oral rinse and the use of simple oral analgesic would suffice in most situations, and symptoms usually begin to subside in a few hours.…”

To study the local epidemiology and clinical presentation after ingestion of oral mucosal irritating plants. Methodology: Cases presenting with immediate oral mucosal irritation after plant product ingestion from July 2005 to June 2009 were retrieved from the Hong Kong Poison Information Centre's clinical database. Their clinical features and management were reviewed. Results: Thirty cases were retrieved and analysed, including 14 males and 16 females. Poisoning occurred all year round with no seasonal predilection. Vomiting and dysphagia were the two most common symptoms other than immediate oral mucosal irritation. Half of the cases could be managed with symptomatic treatment and discharged after a few hours of observation. Six patients presented with angioedema and were managed initially with the use of intravenous steroid, antihistamine and with or without adrenaline. Urgent airway assessment with laryngoscope was performed in 3 patients. No patient required endotracheal intubation. Conclusion: Oral mucosal irritating plant ingestion is not uncommon in Hong Kong. Its clinical feature can mimic angioedema on presentation. Immediate and localized oral mucosal symptoms after plant product ingestion are the key to diagnosis.
