Primary ciliary dyskinesia--an underdiagnosed entity.

Primary ciliary dyskinesia (PCD) also known as immotile cilia syndrome is a genetic disorder characterised by chronic infections of the upper and lower respiratory tracts, male infertility and situs inversus totalis. Authors are presenting clinical details of a patient who was operated upon for recalcitrant rhinosinusitis. Investigations carried to find out the predisposing factors for such sinusitis, resulted in diagnosing the patient a case of PCD, a rare but well known cause of recalcitrant sinusitis.
