A rare cause of specific cough in a child: the importance of following-up children with chronic cough.

For many years, the term 'specific cough' has been used as a clinical cough descriptor in children to signify the likelihood of an underlying disease causing the cough. In this case study, we describe a child with specific cough caused by a rare carcinoma, a mucoepidermoid carcinoma of the bronchus. The cough only totally resolved after the primary cause was successfully treated. This report highlights the importance of following up children with cough, especially those with specific cough.
