Pharmaceutical tablets meant for oral consumption are modified into solutions for injection. Excipients\u2014inactive substances that serve as vehicles for medication\u2014are often not filtered out before injection and result in abscess formation, granulomatous inflammation, and scarring. Common excipients used in the production of pharmaceutical tablets include starch, microcrystalline cellulose, magnesium stearate, silica, and polyvinylpyrrolidone (PVP). Identification of these exogenous materials is valuable in confirming the diagnosis of skin popping, especially when patients may not be forthcoming about their drug use. We present a case of subcutaneous oral medication injection in which PVP and cellulose were identified by Fourier transform infrared spectroscopy. Considering the variable cutaneous manifestations of injection drug abuse, recognition of histopathologic and chemical characteristics of exogenous material from oral medications is helpful for diagnosis and intervention.<\/jats:p>","DOI":"10.1111\/cup.13819","type":"journal-article","created":{"date-parts":[[2020,7,26]],"date-time":"2020-07-26T08:08:08Z","timestamp":1595750888000},"page":"1067-1072","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Injection of oral medication into the skin confirmed by infrared spectroscopy"],"prefix":"10.1111","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9845-4742","authenticated-orcid":false,"given":"Rachel L.","family":"Flint","sequence":"first","affiliation":[{"name":"Uniformed Services University  Bethesda Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ari","family":"Gelman","sequence":"additional","affiliation":[{"name":"Department of Dermatology Brian Allgood Army Medical Center  South Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francis M.","family":"Chiricosta","sequence":"additional","affiliation":[{"name":"LabCorp  San Diego California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stacy","family":"Strausborger","sequence":"additional","affiliation":[{"name":"Joint Pathology Center  Silver Spring Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Lewin\u2010Smith","sequence":"additional","affiliation":[{"name":"Joint Pathology Center  Silver Spring Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sunghun","family":"Cho","sequence":"additional","affiliation":[{"name":"Uniformed Services University  Bethesda Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,18]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.visj.2019.01.003"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.drugpo.2014.06.016"},{"key":"e_1_2_4_4_1","first-page":"102","volume-title":"Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems","author":"Allen LV","year":"2014"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(85)70231-9"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1086\/313703"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-198502000-00016"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.2.5710.647"},{"key":"e_1_2_4_9_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0113991"},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(72)80052-2"},{"key":"e_1_2_4_11_1","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1969.00300160046008"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-198405000-00008"},{"key":"e_1_2_4_13_1","unstructured":"HYDROCODONE BITARTRATE AND ACETAMINOPHEN tablet [package insert].
