16-year-old, previously healthy girl complained of coughing up small, round “brainlike” structures for the last 6 weeks (Image 1). The cough was always preceded by a foreign body sensation or “something stuck” in the throat. The episodes occurred 3-4 times a week and were often associated with choking. Examination Examination of the oral cavity revealed slightly enlarged tonsils without exudates. The rest of the examination results were normal. During her first visit to clinic, she handed over 2 small, lobulated masses of white-gray material, which she had expectorated during the last few days (Image 1).

The material was sent for histopathologic examination (Image 2). What is your diagnosis? *This patient case is from Docplexus Editorial Team for educative purposes only. Source: JAMA Pediatrics The answer is posted in the comment section. click here .
