Dermatitis Venenata Due to Ginkgo Berries

Eighty-three cases of dermatitis caused by wood or sawdust have been seen at St John's Hospital for Dieases of the Skin, London, in the last 20 years. The clinical details and results of patch tests are reported. The literature on dermatitis, mucosal irritation, asthma and other toxic effects of woods of some 300 botanical species is reviewed at length, with an index of scientific, trade and vernacular names, chemical formulae of the known sensitizing substances, and a table of the 28 toxic woods most often encountered. Pathogenesis, diagnosis and prophylaxis are discussed.

“…Contact with the fruit of the ginkgo tree can induce allergic contact dermatitis, 14 most often as erythematous papules, vesicles, and in some cases edema. 5,15 Exposures While Picking Berries-In 1939, Bolus 15 reported the case of a patient who presented with edema, erythema, and vesicular lesions involving the hands and face after picking berries from a ginkgo tree. Later, patch testing on this patient, using ginkgo fruit, resulted in burning and stinging that necessitated removal of the patch, suggesting an irritant reaction.…”

“…It is grown worldwide for its beauty and longevity. The female ginkgo tree is a gymnosperm, producing fruit with seeds that are not coated by an ovary wall 15 ; male (nonfruiting) trees are preferentially planted because the fruit is surrounded by a pulp that, when dropped, emits a sour smell described variously as rancid butter, vomit, or excrement. 5…”

Contact with the Ginkgo biloba tree can cause allergic contact dermatitis; ingestion can cause systemic dermatitis in a previously sensitized patient.• Ginkgo biloba can cross-react with plants of the family Anacardiaceae, such as poison ivy, poison oak, poison sumac, cashew tree, and mango.• Ginkgo extract is widely considered safe for use; however, dermatologists should be aware that it can cause systemic dermatitis and serious adverse effects, including internal hemorrhage and convulsions. FIGURE 1. Gingko biloba can grow to approximately 100 feet.

“…The lesions consist of erythematous papules and vesicles, with severe swelling in severe cases. They usually affect the face, the forearms and the thighs, and sometimes the genitalia [142,143]. Stomatitis, cheilitis, and proctitis following ingestion of ginkgo fruit were described [144].…”
