AB  - 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.
