I apologize that this week's case is rather disturbing - and not in usual the creepy crawly parasite way.
The following structure was coughed up by a 70-year-old woman with advanced stage lymphoma. She had recently received chemotherapy consisting of rituximab, ifosfamide, carboplatin and etoposide (R-ICE). At the time, she was quite ill and in the intensive care unit. Likely identification?
