TY - JOUR T1 - A 45-Year-Old Man With a Lung Mass and History of Charcoal Aspiration JF - Respiratory Care SP - 1251 LP - 1254 VL - 51 IS - 11 AU - David B Seder AU - Robert A Christman AU - Michael O Quinn AU - M Elizabeth Knauft Y1 - 2006/11/01 UR - http://rc.rcjournal.com/content/51/11/1251.abstract N2 - A 45-year-old man was seen in consultation for evaluation of a spiculated right-lower-lobe mass that enlarged over 1 year. The patient had suffered accidental instillation of activated charcoal into the right lung via nasogastric tube 2 years prior to this consultation, with resultant respiratory failure, pneumonia, and pneumothorax. Biopsy of the mass showed anthracosis and granulomatous inflammation. A positron emission tomogram was strongly positive at the lesion, and right-lower-lobectomy with partial diaphragmatic resection was performed. On gross examination of the mass, a charcoal concretion was evident. Histologic examination showed intrinsic and surrounding granulomatous inflammation, but without tumor. The patient recovered uneventfully, and after 1 year had not experienced further complications. ER -
