In the first case, a healthy 7-y-old male presented with a rash consisting of black dots with localized surrounding erythema on the left arm. The rash then progressed to a vesicular, pinpoint, raised rash spreading to the face, arms, and neck. In the second case, a 4-y-old male presented with non-pruritic, black, flat, non-erythematous lesions that did not progress. This patient\u2019s older sibling had been diagnosed with poison ivy 1 wk prior, and they attended the same child care where the poison ivy was thought to be acquired. In both cases, diagnosis of black-spot Toxicodendron dermatitis was made. The black spot of Toxicodendron dermatitis is caused by urushiol oxidation on exposure to air. The subject may or may not go on to develop allergic contact dermatitis after the exposure. Diagnosis of this dermatitis is made on clinical presentation, with careful consideration of history, distribution, and lesion morphology. When allergic dermatitis does develop as in the first case, systemic treatment with oral steroids is recommended. In both of these cases the black dots completely resolved in 2 to 3 wk. Dermatologic referral for dermoscopy and biopsy may be necessary if the dermatosis does not resolve as anticipated. <\/jats:p>","DOI":"10.1016\/j.wem.2022.05.002","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T08:52:27Z","timestamp":1655455947000},"page":"351-354","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Black-Spot Toxicodendron Dermatitis With Varied Presentation"],"prefix":"10.1177","volume":"33","author":[{"given":"Emily P.","family":"Rabinovich","sequence":"first","affiliation":[{"name":"University of Virginia School of Medicine, Charlottesville, VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer N.","family":"Barquin","sequence":"additional","affiliation":[{"name":"University of Virginia School of Medicine, Charlottesville, VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca E.","family":"Abernathy","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Virginia Health System, Charlottesville, VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert J.","family":"Koester","sequence":"additional","affiliation":[{"name":"School of the Environment, Geography and Geosciences, University of Portsmouth, Portsmouth, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2022,9,1]]},"reference":[{"key":"bibr1-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1097\/DER.0000000000000472"},{"key":"bibr2-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1614\/WS-06-190"},{"key":"bibr3-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-5347(00)88977-6"},{"key":"bibr4-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1580\/PR31-05.1"},{"key":"bibr5-j.wem.2022.05.002","first-page":"461","volume-title":"Fisher\u2019s Contact Dermatitis","author":"Fisher A.A.","year":"1995","edition":"4"},{"key":"bibr6-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(80)80047-8"},{"key":"bibr7-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1093\/oso\/9780195155488.001.0001"},{"key":"bibr8-j.wem.2022.05.002","first-page":"1414","volume-title":"Wilderness Medicine","author":"Freeman E.E.","year":"2012","edition":"7"},{"volume-title":"Rhus Dermatitis: From Rhus Toxicodendron, Radicans and Diversiloba (Poison Ivy) Its Pathology and Chemotherapy","year":"1923","author":"McNair J.B.","key":"bibr9-j.wem.2022.05.002"},{"key":"bibr10-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1111\/j.1745-7599.2011.00615.x"},{"key":"bibr11-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1067\/mjd.2001.114295"},{"key":"bibr12-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdcr.2017.09.035"},{"issue":"7","key":"bibr13-j.wem.2022.05.002","first-page":"32","volume":"37","author":"Sivan K.","year":"2020","journal-title":"Contemp Pediatr"},{"key":"bibr14-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.5070\/D308F5C7S0"},{"key":"bibr15-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(82)70030-1"},{"key":"bibr16-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1001\/archderm.135.8.1002"},{"issue":"6","key":"bibr17-j.wem.2022.05.002","first-page":"429","volume":"6","author":"Curtis G.","year":"2014","journal-title":"J\u00a0Clin Med Res"},{"key":"bibr18-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1016\/0190-9622(90)70297-U"},{"issue":"3","key":"bibr19-j.wem.2022.05.002","first-page":"300","volume":"166","author":"Goodall J.","year":"2002","journal-title":"CMAJ"},{"issue":"4","key":"bibr20-j.wem.2022.05.002","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1080\/00325481.1999.11444996","volume":"106","author":"Moe J.F.","year":"1999","journal-title":"Postgrad Med"},{"key":"bibr21-j.wem.2022.05.002","doi-asserted-by":"publisher","DOI":"10.1093\/oso\/9780195155488.001.0001"},{"key":"bibr22-j.wem.2022.05.002","first-page":"S98","volume":"42","author":"Davila A.","year":"2003","journal-title":"Ann Emerg Med"}],"container-title":["Wilderness &amp;
